CHAPTER 2
PHYSICAL FEATURES
2.1 GENERAL
There are few places on earth that are special and Odisha is one of them. It is a
fascinating land filled with exquisite temples, monuments and possessing beaches,
wild life, sanctuaries and natural landscape of enchanting beauty.
The project area falls in Koraput and Malkangiri district of Odisha having its
geographical area as 5294.5 Sq. Km. The district is bounded by Rayagada and
Srikaklam district on its East side, Bastar district on the west, Malkangiri district on
South-west side, Nabarangpur district on north and Vishakhapatnam on south.
Malkangiri and Koraput districts are situated at 18°35’ Latitude and 82°72’ Longitude
at an average elevation of 170 and 870 m respectively from mean sea level. The
district’s demographic profile makes it clear that it is a predominantly tribal and
backward district with 56% tribal and 78% of the rural families below poverty line
(BPL).
The region is characterised by high temperature and humidity in most parts of the year
and medium to high annual rainfall. There is a considerable extent of natural
vegetation in this region. The hydrographical features also reflect these effects. The
chapter describes the general topographical and physical features of the Kolab basin
and the project command area.
2.2 PHYSIOGRAPHY
Odisha State lies within latitude 17° 48 to 23° 34 and longitude 81° 24 to 87°29 and is
bounded on the north by Jharkhand, on the west by Chhattisgarh, on the south by
Andhra Pradesh and on the north-east by West Bengal. On the south-east, is the Bay
of Bengal with a coastline of 480 Km. The State consists of 30 districts covering an
area of 1,55,820 SqKm.On the basis of homogeneity, continuity and physiographical
characteristics, Odisha has been divided into four major regions:
1. The coastal plains in the east
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-2: Physical Features 2-2 2
2. The middle mountainous and highlands region
3. The central plateaus
4. The western rolling uplands
The principal rivers include the Mahanadi, Brahmani and Baitarani, the others being
the Subarnarekha,Indravati,Machhkund,etc. The Chilka Lake, the widest lagoon in
India, is a prominent coastal feature in the State.
The Odisha Coastal Plains or Utkal Plains are the depositional landforms of recent
origin and geologically belong to the Post-Tertiary Period. The 75 meter contourline
delimits their western boundary and differentiates them from the Middle Mountainous
Region. This region stretches from the West Bengal border, i.e. from the River
Subarnarekha in the north to the River Rushikulya in the south.
This region is the combination of several deltas of varied sizes and shapes formed by
the major rivers of Odisha, such as the Subarnarekha, the Budhabalanga, the
Baitarani, the Brahmani, the Mahanadi, and the Rushikulya. Therefore, the coastal
plain of Odisha is called the "Hexadeltaic region" or the "Gift of Six Rivers". It
stretches along the coast of the Bay of Bengal having the maximum width in the
Middle Coastal Plain (the Mahanadi Delta), narrow in the Northern Coastal Plain
(Balasore Plain) and narrowest in the Southern Coastal Plain (Ganjam Plain). The
North Coastal Plain comprises the deltas of the Subarnarekha and the Budhabalanga
rivers and bears evidences of marine transgressions. The Middle Coastal Plain
comprises the compound deltas of the Baitarani, Brahmani and Mahanadi rivers and
bears evidences of past 'back bays' and present lakes. The South Coastal Plain
comprises the laccustrine Plain of Chilika Lake and the smaller delta of the
Rushikulya River.
The middle mountainous and highland region covers about three-fourth of the entire
State. Geologically it is a part of the Indian Peninsula which as a part of the ancient
landmass of the Gondwanaland. The major rivers of Odisha with their tributaries have
cut deep and narrow valleys. This region mostly comprises the hills and mountains of
the Eastern Ghats which rise abruptly and steeply in the east and slope gently to a
dissected plateau in the west running from north-west (Mayurbhanj) to south-west
(Malkangiri). This region is well marked by a number of interfluves or watersheds.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-2: Physical Features 2-3 3
The Eastern Ghats is interrupted by a number of broad and narrow river valleys and
flood plains. The average height of this region is about 900 metres above the mean
seal level. The highest peak is Deomali.
The central plateaus are mostly eroded plateaus forming the western slopes of the
Eastern Ghats with elevation varying from 305–610 metres. There are two broad
plateaus in Odisha: (i) the Panposh – Keonjhar -Pallahara plateau comprises the
Upper Baitarani catchment basin, and (ii) the Nabrangpur – Jeypore plateau comprises
the Sabari basin.
Western rolling uplands are lower in elevation than the plateaus having heights
varying from 153 metres to 305 metres.

2.3 STRUCTURE AND TECTONICS
The regional trend in the Eastern Ghats belt is dominantly N.E. – S.W. in the south –
western part (Koraputdistrict) which gradually changes to N.-S. in the western part (
Kalahandi district ) and then to E.N.E.- W.S.W. through N.E.- S.W. in the northern
part . The E.N.E. - W.S.W. trend in the Bolangir district abruptly changes to N.W. -
S.E. trend ( Mahanadi trend ) and continues in the north – eastern part of the orogen (
eastern Phulbani , Dhenkanal, Cuttack and Puri District ) until it disappears under the
coastal sedimentary cover . This spectacular change in the trend is considered to be
due to major cross folding alone a N.W. – S.E. axis. That superimposed or cross
folding had taken place is amply evidenced from the result of structural studies
carried out several workers in part of the belt. Further, it is likely that the
emplacement of the anorthosite bodies in the Puri and Bolangir districts is controlled
by these cross fold movements. The abrupt change in Mahanadi trend in the north –
eastern part is interpreted to be due either to the presence of large steeply plunging
folds or to the later movement on the marginal part of the craton (Chatterji et al,
1971).
2.4 REGIONAL GEOLOGY AND STRATIGRAPHY
The strata of Orissa state forms a part of the north eastern extension of the Peninsular
shield. Orissa state is by and large underlain by Precambrian rocks. A little less than
25 percent of the total area of the state is constituted of the Phanerozoic rocks,
quaternary formations and the recent to sub-recent alluvium.
Particularly in Koraput district, the existence of remnants of Laterite and Bauxite
covered plantation surfaces (erosion plains) at different altitudes leaves no doubt that
the land was subjected to one of the most epeirogenic movements, probably in the
quaternary period.
It is proposed to include the group of Meta sediments and basic rock (Sukma Group)
occurring in the South-Western part of Orissa in Koraput district in the iron ore group.
However, the trends vary from north-south in the Sukma rocks (Koraput) to east-
western in the Sambalpur district. Orissa has been divided into five major
morphological regions, which are as under:
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-2: Physical Features 2-5 5
1) Orissa Coastal plain in the east.
2) The middle mountains.
3) The Central Plateau
4) The Western rolling uplands
5) The major flood plains
The Kolab/Sabari basin lies in Nabarangpur-Jeypore Plateau. The Plateau is most
eroded plateau forming the western slopes of Eastern Ghats with elevation varying
from 305-610 meters.
Dam Site Area-Geological Set up
The river Kolab/Sabari flows in S280W direction at the proposed dam site. The rocks
exposed on both the banks at site are mainly banded quartzite with shales. The
quartzites are also generally exposed in the river bed section at the site but the length
of the dam including dykes shall be of the order of 6000m and a number of dykes are
also required at the proposed site.
The rocks in the area are well jointed and are traversed by Shear Zones in different
direction.
Bane of Orissa –Cyclones-Vulnerability and Impact Vulnerability
The Indian sub-continent has a long coastline of 8.41 Kilometers and is highly prone
to tropical cyclones, the majority of them have their initial genesis over the Bay of
Bengal and strike the east coast of India. On an average, five to six tropical cyclones
occur every year of which two or three could be severe. More cyclones occur in the
Bay of Bengal than the Arabian Sea and the ratio is 4:1.
In Orissa, the cyclones are usually experienced in the post monsoon period, normally
in the month of October and November.
Impact: At this time, the Kharif paddy is generally in the flowering stage. The
flowers being blown off by strong winds, damage the paddy crop seriously. When
lashed into severe cyclonic storm, the very economic structure gets hit in the Coastal
districts.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-2: Physical Features 2-6 6
The fertile affected land of the Coastal districts may extend about 25 Km inland. 75%
of the people in the area depend upon agriculture and 5% on fishing. About 90%
population lives in thatched roof houses. The Communication system of the area is
extremely poor. The weaker sections of the society in these coastal districts have not
been able to improve their economic condition. On account of frequent floods, saline
inundation and severe cyclones, the state in the recent years has suffered extension
losses due to super cyclones.
Floods, droughts and cyclones occur almost every year with varying intensity.Due to
frequent occurrences of these natural calamities, there is always reduction in Kharif
crop say rice. Similarly, in drought years, there is considerable loss in production of
pulses and oilseeds crops during Rabi and Kharif season.
Post Initiatives taken so far tackling the cyclone problem
In the wake of severe cyclones which affect mainly along the Eastern coast region
states, the Govt. of India, in the erstwhile Ministry of Irrigation and Power, appointed
a cyclone distress Mitigation Committee in December,1969 to examine various
measures to mitigate human sufferings and reduce the loss of life and property in the
event of recurrence of such cyclones.
With a view to reduce the cyclone distress, the Committee recommended construction
of cyclone shelters, dredging of the mouths of big drains, construction of the raised
platforms for stacking harvested crops, improvement of road communication between
various villages prone to cyclones, setting up of cyclone relief committees etc.
Subsequently, a High Powered Committee (HPC) on Disaster Management (DM) was
constituted in 1999, to prepare comprehensive model plans for the management of
disasters at the national, state and district levels. Accordingly, the state government
set up State Crisis Management Groups headed by Chief Secretaries, designated relief
Commissioners and put in place State/District Contingency plans.
Subsequent Initiatives by State of Orissa
The Govt. of Orissa constituted the Orissa State Disaster Mitigation Authority
(OSDMA) as a Government owned autonomous body after the Oct 1999, super
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-2: Physical Features 2-7 7
cyclone to have a systematic and planned approach to Disaster Management in the
state with the objective of making the people of the state more disaster resilient.
OSDMA coordinates various activities of disaster mitigation in the state including
capacity building of the community and disaster managers and strengthening of
infrastructure system etc.
The Govt. of Orissa has constituted five units of Orissa Disaster Rapid Action Force
(ODRAF) which is specially trained and equipped force to deal with cyclones and
other disasters. They are stationed at Jharsagnde/ Balasore, Cuttack, Chhatarpur and
Koraput. Besides, Orissa has established an extensive VHF network connecting
different levels of administration and the community to communicate cyclone
warnings and advisories.
Mineral and Metal Scenario
Orissa is the leading producer of chromite, graphite, bauxite, manganese ore, iron-ore,
sillimanite, quartzite, pyroxenite and dolomite.
The state hosts country’s sole resources of ruby and platinum group of metals. It
accounts for country’s 95% chromite, 92% nickel ore, 69% Cobalt ore, 55% Bauxite,
51% titaniferous magnetite, 40% limestone, 36% pyrophyllite, 33% iron ore (heamite)
, 26% sillimanite, 25% each fireclay and garnet, 24% each coal and zircon and 20%
vanadium ore resources.
Important minerals that occur in the state are bauxite in Boudh, Bolangir,
Kalahandi,Keonghar, Koraput, Malkangiri and Sundargarh districts. Chromite in
Balasore, Cuttack, Dhankamal, Jajpur and Keonjhar districts, China clay in Bargarh,
Bondh, Belangir, keonjhar, Mayurbhanj, Sambalpur and Sundargarh districts,
Chromite deposits of Sukinda and Nuasahi ultramafic belt constitutes 95% of the
country’s chromite resources. Coal occurs in Ib river valley coalfield.
Sambalpur district and Talchar Coalfield, Dhenkamal district , dolomite in Keonjhar,
Koraput, Sambalpur and Sundargarh districts , quartz/Silica sand in Boudh, Bolangir,
Keonjhar, Koraput, Sambalpur, and Sundargarh districts, Pyrophylite in Keonjhar and
Indargarh districts, Pyrophylite in Keonjhar districts, tale in Keonjhar, Mayerbhanj
and Sambalpur district, titanium mineral in Dhunkanal, Ganjam, Jajpur and
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-2: Physical Features 2-8 8
Mayurbhanj, districts. Other Minerals that occur in the state are Cobalt in Cuttack and
Jajpur districts, Copper in Mayurbhanj and Jambalpur districts and granite in Angul,
boudh, Balangir, cuttack, Deogarh, Dhunkanal, Ganjam, Keonjhar, khurda, Koraput,
Mayurbhanj, Nuapada, Rayagada.
Industry:- In an underdeveloped region where agriculture is the most important
means of livelihood, economic growth of the people inhabiting in the area occurs
basically through rise in productivity in agricultural produce supported by an
expanding agro-based industries and industries based on the raw material available
within the area. In addition to abundant agriculture produce , the basin has a large
forest area and deposits of raw materials for industrialization. The available raw
materials in shape of Ore and minerals are iron ore, manganese, coal, lime-stone,
bauxite, graphite, chromite, dolomite, china clay etc. Precious stones and Diamonds
are also available in the basin.
At present, some of industries like cement, iron, sugar mill, oil mill, rice mill, textile,
paper, cardboard, refractories, ceramic, glass etc. exist in the region. Water and coal
being available in plenty, with the availability of power and there being vast natural
resources and with fairly developing infrastructure, there is great potential for
development of industries within the state.
Most of the mineral output is presently transported to other parts of the country for
processing. But with the Govt. initiatives, of late, there are plans afoot to set up
industries in the state itself, so as to achieve the national goal in improving the living
standard of its people by providing jobs and also cut expenses on transportation.
2.5 MINERAL OCCURENCES
2.5.1 Graphite
Graphite deposits occur in association with the Eastern Ghat rock types of
Precambrian age. They are found along the contact zone of khondalitic rocks with the
granite gneiss, associated with the pegmatite bodies. The deposits appear to be
epigenetic in origin and are structurally controlled along the foliation, fracture planes
and fault zones. The ore is erratic in behaviour and occurs in small veins over strike
lengths of a few metres to 200 m. The thickness also varies from a few centimetres to
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-2: Physical Features 2-9 9
three metres. The mineral is flaky and crystalline in nature and its carbon content
from 30 % to as much as 80%. The deposits are distributed as follows:-
1) Sargipali belt in Sambalpur and Bolangir district ( lat . 20 30’ – 21 00’ long . 82 40’
– 83 51’).
2) Titagarh belt in Bolangir and Kalahandi districts (lat. 20 02’ – 20 28’: long . 83 00’
– 83 35’)
3) Tumdibandh belt in Phulbani districts ( lat. 19 45’- 20 00’ :long. 83 25’ – 83 50’ )
4) Dandatapa belt in Dhenkanaldistricts ( lat. 20 45’- 20 50’ : long. 84 20’ – 84 40’ )

CHAPTER 3
INTERSTATE ASPECTS
3.1 GENERAL
Orissa located on the east coast of India by the Bay of Bengal is the ninth largest state
by area and the eleventh largest by population. It has a relativelyunidented coastline
about 480 km long. The narrow level coastal strip including the Mahanadi River delta
supports the bulk of population. The interior of the state is mountainous and sparsely
populated. Deomali at 1672 m is the highest point of the state. Orissa is subjected to
intense cyclones, the most intense one in October 1999 causedsevere damages besides
10,000 deaths.
3.2 BACKGROUND
3.2.1 River Basin: Kolab River originates from the Sinkaran Hills of the Eastern Ghats in
Koraput district and finally meets the Godavari in Andhra Pradesh. The prominent
tributaries of KolabareKarandi Nallah, Guradi Nalla, Kangar Nallah, Garia
Dharmagidi Nallah, Jam Nadi, Mabengar River, Mulervagar Nallah, Machhakund
River, Sileru River.
3.2.2 Project
The Middle Kolab project envisages construction of a barrage across river Kolab
about 5.0 km downstream of confluence of Jaura Nallah with Kolab and upstream of
Dumajori Village in Koraput district of Orissa. The catchment area intercepted is
1473 sq. km. Adam is proposed on Kerajodi, a small tributary of Kolab River. A link
canal is also proposed of length about 38.55Km whichwill divert the water from the
diversionbarrage to the catchment of Kerajodi dam.
It is proposed to generate hydro power at a power house proposed near village
Kodukugurah. With an available grosshead of about 252.7 m at the point, it is
proposed to generate 200 MW of power if the weir in Joura Nallah is commissioned
and 315 MW if present situation continues. After power generation, the released water

Chapter-3: Interstate Aspects 3-2
will be picked by implementing a barrage on Kolab. It is proposed to create irrigation
potential of about 25,543 ha in Maithili block of Malkangiri district.
3.3 INTER STATE ASPECT/ANGLE - INVOLVEMENT AND APPRAISAL
3.3.1 Inter State Rivers
All the major river basins (drainage area more than 20,000 sq km and some among the
medium river basins (drainage area more than 2000 sq km and less than 20,000 sq
kms) are interstate, having the drainage area lying in more than one state/union
territory. Thus,all major projects and almost all medium projects of the state are
referred to CWC, for examination from interstate angle.
Thus, any project, which is located on an interstate river or its tributary, will be
deemed to involve interstate aspects/issues and as per planning commission
guidelines, shall need investment clearance from the planning commission, as per the
procedure in vogue.
Before consideration of such a project for investment clearance, the concerned
state/U.T. Govt. shall approach the Central Water Commission to obtain
confirmation/certificate from CWC to the affect that the proposed project is not
located on the interstate river on its tributary.
At present, the Planning Commission accords investment clearance in case of all the
major irrigation and/ or multipurpose projects (having CCA more than 10,000
hectare) and in the case of medium projects (having CCA less than 10,000 hectare and
more than 2000 hectare) only for those projects, where interstate angle is involved,
after techno-economic appraisal by Central Water Commission, followed by the
acceptance by the Advisory Committee on Irrigation, Flood Control and multipurpose
projects of Ministry of Water Resources.
3.3.2 Involvement of Interstate Aspect
Any major irrigation or multipurpose project and in case of medium irrigation project,
it is said to involve interstate aspect if all or any of the following issues are involved.
1. Sharing of water
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-3: Interstate Aspects 3-3
2. Sharing of costs
3. Sharing of benefits
4. Acceptance of Submergence by the upstream state
5. Compensation of land coming under submergence
6. Settlement of oustees
7. Any other common issue
In the past, some of the states had resolved their disputes on sharing of water or joint
projects through internal discussions and agreements without the direct intervention of
the Central Govt. Wherever, this was not possible, central Govt had intervened and
played a major role in resolving the disputes.
About 114 interstate agreements have been reached so far.
3.3.3 Guidelines for distribution of water among the states
At present, there are no specific guidelines for distribution of water among the states.
In the past, efforts were made by National Water Resources Council for framing the
guidelines, but no consensus could emerge on the guidelines. Guidelines for
distribution of water among the stats would be helpful in appraisal of projects of such
basins where no agreement / decision of tribunal exist.
3.3.4 Interstate Agreements
A number of agreements have been made with Orissa regarding utilization of waters
of Mahanadi and its tributaries.Regarding INTER STATE Matters between Orissa
and Madhya Pradesh, the following agreements were arrived at in respect of water
resources development for irrigation and power projects.
Prominently, the Memorandum of Agreements reached in presence of discussions
held on 27th April, 1983 at Bhubaneswar attended by Shri Arjun Singh, Chief Minister
Madhya Pradesh and Shri Bhallab Patnaik, Chief Minister Orissa and Shri Narayan
Patnaik, Minister of State for irrigation and power, Orissa along with the concerned
officials of the two states. In the past, the following Projects have undergone the
interstate aspects/issues. But the Middle Kolab Project doesn’t figure among these
projects.

3.3.5 Constitutional Provisions
Article246 of the constitution deals with the subject matter of laws to be made by
Parliament and by the legislature of the states. The allocation of responsibilities
between the centre and the states in respect of laws to be made fall into three (03)
categories as under:-
1. The union list (List - 1)
2. The state list (list-II)
3. The concurrent list (list - III)
Subject of ‘Water’ is a matter at entry ‘17’ of list-II i.e. state list. This entry is subject
to the provisions of entry 56 of list-I, the union list. The specific provisions in this
regard are as under:-
Entry 56 Under List-I
Regulation and Development of Inter State rivers and river valleys to the extent to
which such regulation and development under the control of the Union is declared by
the Parliament by law to be expedient in the public interest Agreement between
Orissa and MP on 9.12.1975.
It was agreed in the meeting between the Chief Ministers of Orissa and Madhya
Pradesh on 9th December 1975 that Madhya Pradesh and Orissa will consider the
feasibility of taking up joint projects in the Sabari/Kolab Sub basin from the point
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-3: Interstate Aspects 3-5
Sabari (Kolab) river forms the common boundary between both the states upto the
point where it joins the Sileru River, on the basis of common agreement to be drawn
up at appropriate time. The hydel power and cost debitable to generation of such
power will be shared equally between the two states in these projects. The cost and
benefit of irrigation, if any from the project will also be equitably shared among both
the states. Orissa will be free to make beneficial use of the water of the river above the
common boundary point and lying in its territory in such manner as it deems fit.
Notwithstanding the agreement on the joint project on the river Sabari (Kolab)
mentioned above, if there is any submergence of land and properties of either state by
other projects sponsored by the other state or any other state in the Godavari basin, the
question of submission and the problems connected therewith will have to be
mutuallysettled before execution of such projects.
Madhya Pradesh and Orissa agree that the agreement will be furnished to the Govt. of
India and they would be requested to expedite the clearance of new projects.
3.4 SUMMING UP
In case of Multipurpose Projects, apart from examination of projects through ISM
Dte; Hydro-electric project and thermal projects received from CEA/State Govt. are
also examined from interstate angle.
In such projects, requirement for consumptive uses has to be within the allocated
share of the state. In case, where allocations are not there, project authorities are
advised to send a copy of DPR to concerned state, with the comments that
consumptive uses from the project shall be accounted against the share of the state in
which the project is located, as and when, an agreement is reached among the Co-
basin states for sharing of water of the river basin.

CHAPTER - 1
INTRODUCTION
1.1 ORISSA STATE
Orissa, located on the east coast of India, by the Bay of Bengal, is the ninth largest
state by area and the eleventh largest by population. Oriya is the official and most
widely spoken language of the state. Orissa has a relatively unindented coastline
(about 480 km long) and lacks good ports, except for the deepwater facility at
Paradeep. The narrow, level coastal strip, including the Mahanadi River delta supports
the bulk of the population. The interior of the state is mountainous and sparsely
populated. Deomali at 1672 m is the highest point of the state. Orissa is subjected to
intense cyclones. The most intense one, in October 1999 caused severe damage and
some 10,000 deaths.
Orissa is home to the Hirakud Dam, one of the longest dams in the world. Orissa has
several popular tourist destinations. Puri, with the Jagannath temple near the sea, and
Konark, with the Sun Temple, are visited by thousands of tourists every year. The
Lingaraja Temple of Bhubaneswar, the Jagannatha Temple of Puri, the Sun Temple of
Konark and the Barabati Fort of Cuttack are important in the archaeological history of
India.
1.2 THE RIVER BASIN
The Kolab River originates from the Sinkaran hills of the Eastern Ghats in Koraput
districts and finally meets the Godavari in Andhra Pradesh. The prominent tributaries
of Kolab are Karandi Nalla, Guradi Nalla, Kangar Nallah, Garia, Dharmageda Nallah,
JamNadi, Malengar River, Mulervagu Nallah, Potteru Vagu Nallah, Machhakund
River, Sileru River.
1.3 THE PROJECT
1.3.1 Aim and Objectives
Middle Kolab Project is aimed to construct/generate
a) A barrage on the river Kolab near Dumajodi village downstream of the confluence
of Joura Nallah the spill channel of Indrāvati river, for diversion of its flows in the
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-1: Introduction 1-2
catchment of Kerajodi Nallah a tributary of the Kolab joining it from the left
downstream of the proposed barrage;
b) A 38.55 Km long flood flow channel for diversion of flows at Diversion barrage
to the catchment of Kerajodi Nallah;
c) A cross drainage work over the above two Nallahs (Kasbal Nallah & MaulaJodi
Nallah) to allow the diverted flows from Diversion Barrage to flow uninterrupted;
d) A balancing reservoir with gross capacity of 13500 Ha-m at Kerajodi, about 24
km downstream of the Kasabal Moulijori Nallah, to regularize flows to the power
house near village Kodukugurah with tail race tunnel leading to the main river.
e) Another barrage on the Kolab further downstream for irrigation of about 24,543
Ha.
f) Two canals one with length of 77.1 Km (to the left bank of Kolab river) and
another with 27.4 Km (to the right bank of the Kolab river)
1.3.2 Location
The Middle Kolab Hydroelectric Project falls in the district of Koraput in Orissa state.
It lies at a latitude of 17o 4’ N to 20o 7’ N and longitude of 81o 24’ E to 84o 2’ E. It is
bounded by Rayagada and Srikaklam district on its East side, Bastar district on the
west, Malkangiri district on South-west side, Nabarangpur district on north and
Vishakhapatnam on south. A Project Location map is shown in WAP/WRD/MKMP/2
1.3.3 Project Planning in Brief
The Middle kolab project envisages construction of a Barrage across river Kolab
about 5.0 km downstream of confluence of Joura Nala with Kolab and upstream of
Dumajori Village in Koraput district of Orissa. The free catchment area is 1473 sq.
km. A dam is proposed on Kerajodi a small tributary of Kolab River with FRL of EL
528 m. A flood flow channel of 38.55 km is proposed from the Barrage to divert the
flood flows of Kolab River into the aforesaid reservoir. It is proposed to generate
Hydro Power at a power house proposed near village Kodukugurah. The gross head
available is 252.7 m at this point as per rough estimate; power generation with
installed capacity of 300 MW considering the present situation and about 200 MW if
the implementation of weir to check flow of Joura Nallah takes place. After power
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-1: Introduction 1-3
generation the released water will be allowed to flow back into Kolab River, which
will be picked by implementing a barrage on Kolab. It is proposed to create an
irrigation potential of 25,543 ha in Mathili block of Malkangiri district.
1.3.4 Accessibility to the Project
The Koraput district is well connected by roads & railways. The nearest airport is
Vishakhapatnam. It is also well connected by roads and NH-43 passes through this
district. It is also well connected to various major cities like Bhubaneswar,
Vishakhapatnam, Chennai, Delhi and Kolkata through a network of trains. There are
in all 3 state Highways running through this district, two of which are fair weather
roads and one namely state Highway No. 4 is the only all-weather road and this
connects Ganjam district.
1.4 GENERAL FEATURES
General features like climate, rainfall, temperature, socio economy, demography, etc.
pertaining to state/ basin are briefly discussed below.
1.4.1 Climate
The Project area has the typical tropical monsoon climate with high summer
temperature and heavy rainfall between June and October. The mean maximum
temperature rises to about 38o C in April and May. The minimum temperature falls to
12o C in December. The average rainfall is 1522 mm. The mean relative humidity
recorded in the morning and evenings are 51.72 and 26.6% respectively. Mean daily
evaporation is about 3 mm in the district. The wind velocity ranges from 4-11 km/hr.
The maximum relative humidity is 72% while the maximum and minimum
evaporation ranges from 1.2 mm to 7.9 mm.
1.4.2 Temperature
December and January are the coldest with mean daily maximum and minimum
temperatures being 24.5oC and 10.3oC. Both of these temperatures increase thereafter
till may which is hottest month with mean daily maximum and minimum
temperatures at 34.3oC and 21.4oC. On individual days in the month of May and June
before the onset of the monsoon, the temperature may shoot above 44oC. The highest

Chapter-1: Introduction 1-4
recorded at Koraput was 46.6oC on 06 June 1967 and the minimum 3.0o C on 27 Dec
1969.
1.4.3 Rainfall
1.4.3.1 Normals and Extremes of Rainfall
Variation in rainfall among various stations may be attributed, prima facie, to the
orographic features of the region and to some extent to the length of data bases. It
may be seen that annual rainfall varies from 1889 mm at Jeypure to 1300mm at
Simliguda. The district average based on mean of stations is 1567 m. Similarly,
Pottangi has the highest number of rainy days (daily rainfall >2.5mm) – 91 and the
Similiguda, the least – 75.8. The district average is 83.9 rainy days.

Middle Kolab Multipurpose Project Detailed Project Report
Chapter-1: Introduction 1-5
1.4.3.2 Sever Rain Causing Systems
The Koraput district which includes whole of the Middle Kolab project area including
Upper Kolab Multipurpose project and its upper catchment is affected by cyclonic
storms and depressions originating from the Bay of Bengal during the south west
monsoon season, and cause strong winds and widespread rain. Their number defines
the difference between the drought and the flood conditions. The Koraput district
faced drought conditions – rainfall less 75% of normal in 5 years between 1901 and
1992 and in seven years it got excess rainfall – more than 125% of normal rainfall
during the same period. Rainfall is considered normal if it lies within 80 to 120% of
its long term mean.
1.4.4 Relative Humidity
Humidity is generally about 80% in the and about 73% in the post monsoon period
and the other months it varies from 53% in the forenoon to 44% in the afternoon.
Skies are heavily clouded to overcast in the monsoon and in the rest of the year light
to clear skies prevail.
1.4.5 Wind
Winds are generally light throughout the year except during the southwest monsoon
season, when winds are stronger.
1.4.6 Evaporation
Evaporation rates are important for preparation of reservoir operating tables. It has a
very significant role to play during a delayed monsoon season when the reservoir
storage is under maximum stress and demand for irrigation, water supply and
hydropower increases manifold. Evaporation rates are generally highest in the
summer months before the advent of monsoon; these may further increase during the
delayed monsoon period owing to rising temperature resulting in severe depletion of
the reservoir.
Observed evaporation data is not available for any station in region. The evaporation
value have, therefore been interpolated from Evaporation Tables published by IMD.
Evaporation depths are measured by using American Class-A Pan Evaporimeter.
Factors prescribed by IMD to convert the observed meshed covered pan data to open

Forests:
The forest area of Mathili block of Malkangiri district is nearly 25082 Sq Km. While
the reserved forests constitute 352.44 Sq Km, protected area as 940.99 Sq Km and
unclassified forest as 0.3 Sq Km. The total forest area covers the dense forest,
moderate dense forest, open forest and scrub.
Minerals:
Orissa produces enormous minerals including nonmetallic, metallic and fuel minerals
like chromite, nickel, iron, Manganese, Fire clay, mineral sands, Graphite, Bauxite,
Lead and zinc. Nearly 10-14 % of mineral production comes from state of Orissa. The
rich reserves of minerals in Orissa have led to establishment of several mineral based

industries in Orissa. Other minerals which are being mined in the State include
Quartz, Quartzite and Soapstone. Many different locations in the state are being
zeroed in for the excavation of gemstones and garnets.
Soil:
Taking into account the soil type, climate and topography the state has been divided
into ten agro climatic zones as shown in the table below. The soil quality index of
Orissa state (0.54) is very low as compared to the neighboring states. The state has
different types of soil types ranging from fertile alluvial deltaic soils in coastal plains,
mixed red and black soils in central table land, red and yellow soils with low fertility
in northern plateau and red, black and brown forest soils in Eastern Ghats region.

1.4.8 Socio economic status
Agriculture is the main source of livelihood of the people of the basin. The economic
growth of the people of the basin can be enhanced only by assured irrigation both in
kharif and Rabi.
1.4.9 Demography
Orissa has a population of 42 million. About 87% of the populations live in the village
and one third of the rural population does not own any land other than homesteads.
25% of Orissa’s population is tribal.
1.4.10 Food and agriculture
The command area lies in Mathili block of Malkangiri district. Agriculture is the
primary occupation of the inhibitants of the basin. A large number of ponds existing
in the basin act as supplement during the period, when there is scarcity of water.
Paddy is the main crop grown in the area in addition to oilseeds, vegetables and
pulses. The gross command area of the block is 37590 sq km excluding forest area.

HYDROLOGY
5.1 MAIN COMPONENTS OF THE MIDDLE KOLAB MULTIPURPOSE
PROJECT
The Middle Kolab multipurpose project envisages construction of following
structures:-
a) A barrage on the river Kolab near Dumajodi village downstream of the confluence
of Joura Nallah the spill channel of Indrāvatiriver, for diversion of its flows in the
catchment of KerajodiNallah a tributary of the Kolab joining it from the left
downstream of the proposed barrage;
b) A cross drainage work over two Nallahs (Kasbal Nallah & MaulaJodi Nallah) to
allow the diverted flows from Diversion Barrage to flow uninterrupted;
c) A balancing reservoir with gross capacity of 13500 Ha m at Kerajodi, about 24
km after crossingof the Kasabal Moulijori Nallah, to regularize flows to the power
house with tail race tunnel leading to the main river/downstream reach of
Kerajodi.
d) Another barrage on the Kolab further downstream for irrigation of about 25,543
Ha.
5.2 HYDROLOGIC INPUTS REQUIREMENTS FOR PLANNING THE
PROJECT
The Middle Kolab multipurpose project system involved construction of a diversion
barrage at Kolab River, one balancing reservoir, a barrage for irrigation and water
conveyance system for irrigation in the command area. The simulation of the system
would have to be done on 10 daily/monthly basis, for as long a period as practicable.
Following is the broad data requirement
i. Data Requirement For The Simulation Studies
a) 10 daily/monthly inflow series for each of the barrage sites in Kolab River, and
reservoir/storage site on its tributary, Kerajodi Nallah.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-5: Hydrology 5-2
b) 10 daily/monthly rainfall and effective rainfall information for the command
areas.If the Kharif irrigation is predominant and requires occasional storage
support,the command area rainfall series has to be concurrent with the discharge
series, so that the different effective rainfall and the difference in storage support
from year to year can be properly seen.
c) Sedimentation data recorded at nearby sites or reservoirs.
ii. Data Required For Flood Related Safety Of The Structures
a) The probable maximum flood for the balancing reservoir/storage dam
b) The standard project flood and return period flood say 50- year or 100-year, as
the case may be,for design of the two barrages.
iii. Construction Related Flood For The Structures
a) Non-monsoon annual peak floods for construction flood of different frequency
5.3 AVAILABILITY OF HYDRO- METEOROLOGICAL DATA
a) Rainfall data
Prior construction of Upper Kolab Dam (UKD) Project, a number of rain gauges had
been installed by the Project authority to record rainfall in and around the upper part
of the catchment for the sake of planning UKD Project. These rain gauges are still
continuing except few which were closed in 1970, after the UKD project report was
prepared. Besides, there are few rain gauge stations being maintained by IMD also.
These rain gauges with period of availability of rainfall data are listed in the Table-
1below.
b) Discharge Data
Upper Kolab Project authority had established a Gauge & Discharge station at
project’s dam site i.e., at Koranga (CA=1630 Sq km), which was closed after planning
of UKD project. Later on, CWC established its own network of G&D Stations on
river Kolab and the river Indravati, from which the spill channel Joura Nallah imports
water to riverKolab. Details of the G&D stations in the vicinity of project, which are
needed for estimation of water availability of Middle Kolab Project, are listed in the
Table-2 below indicating the period of availability of flow data.

The discharge data observed at above G & D stations in 10-daily/ monthly format are

5.4 PAN EVAPORATION DATA
The observed pan evaporation data is important both for estimating the likely
reservoir evaporation and for estimating the likely evapo-transpiration from irrigated
areas.From reservoir, water is lost due to evaporation which needs to be considered
while carrying out simulation studies. Evaporation rates are important for preparation
of reservoir operation tables. It has a very significant role to play during a delayed
monsoon season when the reservoir storage is under maximum stress and demand for
irrigation, water supply and hydropower increases manifold. Evaporation rates are
generally highest in the summer months before the advent of monsoon; these may
further increase during the delayed monsoon period owing to rising temperature
resulting in severe depletion of the reservoir. Observed evaporation data is not
available for any station in the region. The evaporation value have, therefore been
interpolated from Evaporation Tables published by IMD. Evaporation depths are

measured by using American Class-A Pan Evaporimeter. Factors prescribed by IMD
to convert the observed meshed covered pan data to open pan and then into the lake or
reservoir evaporation depths are discussed in this chapter under the paragraph on
reservoir evaporation.

5.5 PROCESSING OF FLOW DATA AS REQUIRED FOR SIMULATION
As already stated, the simulation would be on 10 daily/monthly basis since the system
has both reservoir and diversion structures. Thus, the processing 10 daily/monthly
data is important.
The processing of the flow data normally consists of:
i) Internal consistency checks such as between river stage and river discharge.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-5: Hydrology 5-6
ii) External consistency checks such as:
Between simultaneous flow of one station and another
Comparison of the shape of the cumulative probability functions (flow
duration curves) of the various stations
Comparison of general statistical properties of the various flow series
Consistency between flow and rainfall
5.5.1 Consistency Check of Observed Data
Before using the observed data for estimation of water availability for the proposed
project, the consistency check of all the observed data were carried out. The missing
gap or absurd figures in case of rain fall recorded (Px) in rainfall series at any station
were first of all filled up or corrected using normal equation as below.
Px = Nx/n {P1/N1 + P2/N2 + P3/N3 ……………. +Pn/Nn}
Where P1, P2,P3 …Pn are precipitation recorded at neighboring stations on the
day of missing rainfall at a particular station.
N1, N2, N3…Nn are the values of normal annual rainfall at individual station.
Nx is the value of normal annual rainfall at the station (X).
And n is the number of stations considered in the vicinity of the station X with
missing gap.
In case of discharge data, gaps or absurd data recorded were corrected with
correlating the concurrent period data at the nearby station showing good coefficient
of correlation or with concurrent period rainfall in thecatchment or by comparing the
adjoining discharge figures to show smooth variation while plotting hydrograph.
Consistency check of rainfall data was done by plotting the double mass curve of
rainfall at few individual station and adjoining station shown below as Fig.-1 to Fig.-4

The above plot and coefficient of correlation support the flows observed at Koranga
site to be reasonably consistent.
Similarly, the consistency check of discharge data observed at Kota (CA=1710

correlating the same with concurrent period catchment rainfall on annual basis. The
coefficient of correlation between these two sets of figures works out as 0.88 and

In order to check the consistency of flow observed at Murthandi site on Joura Nallah,
which is the spill flow from river Indravati to river Kolab, the flow observed in
Indravati at Jagdalpur located downstream of the off- take point of Joura Nallah were
scrutinized.
Superimposed plot of above annual flows for the concurrent period, in Fig – 9 below,
shows more or less the similarity in variation but the distinct similarity appears after
the year 1993-94 onward when the spill channel might have achieved nearly

In view of the above, the observed flow data of Joura Nallah at Murthandi can be
considered as consistent.
5.6 ESTIMATION OF WATER AVAILABILITY
As stated above, the catchment of the river Kolab at Middle Kolab Project site is not a
virgin catchment. Construction of Upper Kolab Dam (UKD) which is under operation
since 1988, intercepts drainage from upper part of the catchment measuring an area of
1630sq.km. Water available at UKD is used for hydroelectric generation after routing
through its reservoir,which hasa live capacity of 1215 MCM. The tail race release is
then routed through the Satiguda reservoir for irrigation use in Satiguda Irrigation
Project having ICA of 44,544 Ha.Balance water available from UKD after irrigation
use will be available for the proposed project from catchment upstream of UKD. In
addition, runoff from the catchment of Kolab between UKD and first diversion
structure of Middle Kolab Project proposed at Dumajodi will be available for the
proposed project. A part of adjoining catchment’s water will also be available as spill
fromIndravatiriver throughJoura Nallah in case the spill channel continues to flow as
at present.
A sketch showing the schematic layout of the proposed Middle Kolab Project is
placed at Plate -1 to understand clearly at a glance. As may be seen from the sketch,
the diverted water from the first diversion structure at Dumajodi will be used to
augment the water availability at Kerajodi Reservoir, before it enters into the power
house. The tail water after the powerhouse flows down to proposed barrage on River
Kolab for irrigation use to CCA of about 25,543ha.
Accordingly, a systematic approach has been followed to estimate the water
availability step by step for the proposed project as follows:
i) Estimation of inflow at UKD and routing through its reservoir for hydel and
irrigation use to get balance water available for Middle Kolab Project.
ii) Estimation of inflow from free catchment between UKD and 1st structure of
Middle Kolab Project.
iii) Estimation of Spill flows from Indrāvati to Kolab through Joura Nallah.
iv) Estimation of inflows from Catchment of Kerajodi.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-5: Hydrology 5-15
v) Estimation of Total inflow at Irrigation Barrage site i.e., inflow from free
catchment between first structure and irrigation barrage plus tail water releases
from Power House and spill flows if any over the upstream structures.
Analysis of available consistent data has been carried out as in succeeding Para to
estimate the water availability as mentioned above.
5.6.1 Water availability from UKD‘s Catchment
In UKD project’s catchment, there is no long term observed data available for
analysis. Hydrological data observed at Koranga and Kota sites for the pre-
construction period of UKD project as stated above in Para 5.2 (discharge data),
Annexure-1(i)& 1(iv),are available which were recorded at the time of planning of
the UKD project.The flow measurements at the two sites have been observed by two
different agencies.Long term rainfall data in the catchment are however, available as
indicated in Para 5.2 (rainfall data), Table -1. Using these data, an attempt has been
made to derive a long term flow series based on best fit rainfall- runoff relation.
Since, the discharge of Kolab River at Koranga and Kota sites has been observed by
two different agencies and that too during different period without any overlapping,
continuity and matching of these two sets of discharge series needs to be tested before
using it to develop suitable rainfall- runoff model. Further, construction of UKD was
in advance stage in year 1986 and the virginity of flow was probably disturbed
thereafter, the observed flow data at Koranga/Kota up to year 1984-85 were
considered.
Based on daily observed flow at Koranga and Kota sites, the monthly flow series at
the two sites, have been derivedfor the period from June 1961 to May 1970 and June
1971 to May 1985 except for the year 1979-80 due to non-availability of observed
flow dataduring the period,which have been appended atAnnexure-1.The catchment
rainfall series for the concurrent period has been worked out using Theission Polygon
method except for the year 1971-72 due to non-availability of station rainfalland
appended in Annexure-3.Superimposed plot of rainfall and runoff with linear trend
thereof is shown in Fig.-11 below.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-5: Hydrology 5-16
FIGURE -11
Annual Rainfall and Corresponding Runoff from Kolab’s Catchment at UKD
The mean annual runoff of the two periods has also been plotted separately thereon. It
is seen from the plot that the falling trend of observed runoff is comparatively more
rapid than that of rainfall in the catchment. Mean annual runoff of latter period has
accordingly reduced. The variability in annual rainfall and observed runoff is
comparatively better matching in case of latter period i.e., observed at Kota by CWC
than that of observed in earlier period observed at Koranga by UKD authority.
Statistical feature of the two sets of data series have been worked out and
tabulatedbelow.

Middle Kolab Multipurpose Project Detailed Project Report
Chapter-5: Hydrology 5-17
On comparison of the figures tabulated above, it is observed that the statistical
characteristics of two sets of flow series i.e., mean and standard deviation differ
considerably. Mean annual flow has reduced by about 20%. The catchment
characteristic also appears to have changed as average annual run-offfactor has come
down from 0.63 to 0.52. In view of theabove, the latest observed flow series i.e., for
the period from June 1971 to May 1985 has been considered suitable for developing
the long term flow series.
Using the concurrent period rainfall and runoff for the period from June 1972 to May
1983, monthly rainfall-runoff models using best fit bi-variant or multi-variant
regression equation were developed and the same are listed below in Table-6.

Validation of Rainfall- Runoff Models
The values of R2,as seen from the table above, support the fitness of the rainfall-
runoff models. However before using the above models for derivation of monthly

Chapter-5: Hydrology 5-18
flow series, these have been validated by comparing the computed flows using the
models with actually observed flows during the same period. Since, the models have
been developed based on observed rainfall and runoff for the period from 1972-73 to
1982-83, the computed monthly flows of1983-84 and 1984-85 have been compared
with the observed flows of respective years. Superimposed plots of observed and
computed flows of each year have been shown in Fig. 12 below for visual
comparison.

for estimation of runoff from concurrent rainfall.

Accordingly, based on observed monthly rainfall, the monthly flow series of river
Kolab at UKD site has been estimated to extend the flow series from 1985-86 to
2002-03 using the models.Retaining the observed flows for the period from 1970-71
to 1984-85, themonthly flow series for the period from 1970-71 to 2002-03 have been
derived and tabulated in Annexure-4.Annual rainfall and the corresponding annual
flows have been plotted as shown in the Fig-14 below,and the trend line plotted
thereon supports the derived flow series to be consistent with the rainfall series in the
catchment.

Middle Kolab Multipurpose Project Detailed Project Report
Chapter-5: Hydrology 5-22
December 42.862
Using the revised area-capacity table of UKD reservoir which is appended at
Annexure-5, detail simulation work had been done and the balance water available
for Middle Kolab Project from UKD’s catchment including return flow @ 10% of
irrigation as well as domestic& Industrial use as considered in normal practice, are
given in Annexure-6.
5.6.2 Water Availability at Diversion Barrage from Kolab catchment at Dumajodi
The free catchment between UKD & Dumajodi spread over 1473 Sq.km does not
have sufficient raingauge stations. Only three number raingauge stations located in the
upper part of the catchment cannot be considered to be representative. Considering
similarity in catchment characteristics meteorological condition with that of UKD’s
catchment, flow series of free catchment between UKD and Dumajodi have been
derived on catchment area proportionate basis. The flow series thus estimated are
appended at Annexure-7(i&ii). Total water availability series from Kolab catchment
at Dumajodi which include the net water available from UKD’s catchment as given in
Annexure- 6 above, is presented in Annexure- 7(iii&iv).
5.6.3 Water Availability In The Form Of Spill From Indrāvati Through Joura Nallah
Joura Nallah , a spill channel off taking from adjoining stream Indrāvati a tributary of
Godavari from its left bank at a place located upstream of Jagdalpur, outfalls into
river Kolab just upstream of the proposed location of Middle Kolab Project. This spill
flow will be added to the water availability of river Kolab from its own catchment at
Dumajodi diversion site, provided the spill channel continues to flow as it is.
The daily measurement of spill discharge is done at Murthandi G&D station by
Central Water Commission. Quantum of annual spill through Joura Nallah has been
correlated with corresponding total flow in Indrāvati measured at Jagdalpur. Yearwise
percentage of spill flow to total flow of Indrāvati at Jagdalpur have been worked out
and tabulated in Table-9below.

From the above table and plot, it is observed that the spill channel viz. Joura Nallah
was on the verge of progressive development till the year 1993-94 and from the year
1994-95, it appears to have achieved nearly stabilized course to transfer about 35 to
37% of Indrāvati’s total flow at Jagdalpur.
Monthly total flow series of Indrāvati at Jagdalpur have been worked out assuming no
spill prior to year 1989i.e., the year of starting discharge observation at Murthandi by
CWC and tabulated in Annexure - 8. The monthly average spill percentage after the
course of Joura Nallah gets stabilized, have been worked out and the same have been
shown in the figure below with value of percentage given in the table below.

5.6.4 Water Availability From Catchments Of Kasbal-Moulijodi And Kerajodi
The link channel taking off from first diversion barrage at Dumajodi to balancing
reservoir at Kerajodi crosses over the two local streams viz Kasbal-Moulijodi (CA=
25.82Sq. Km)and intercepts the flow of Kerajodi (CA= 25.55 Sq. Km). Inflows from
Kasbal-Moulijodi will contribute to the water availability at irrigation
barrage,whereas the inflows from Kerajodi catchment will be additionally available
for the balancing Reservoir ofMiddle Kolab Project, as there is proposal for
construction of adam across the stream.
Since these small catchments have similar topographical as well as meteorological
characteristics, inflows from the catchment have been estimated simply on catchment
area proportionate basis from virgin flow series , which has already been annexed in
Annexure–4, pertaining to catchment lying upstream of UKD. The monthly flow
series from the Kerajodi catchment thus derived are tabulated in Annexure-10.
In case, for some technical reasons, the construction of weir/dam over Kasabal-
Moulijodi is not feasible, inflows from Kasabal-Moulijodi catchment will not be
available for power house of Middle Kolab Project and water from this catchment will
be available directly for Irrigation barrage.
5.6.5 Water Availability At Proposed Irrigation Barrage Of Middle Kolab Project
The free catchment of Kolab below Dumajodi will contribute to water availability at
the barrage site in addition to overflows from upstream diversion structure, inflow of
Kasbal-Moulijodi Nallah and the tail water releases from power house of Middle
Kolab Project. In order to estimate the inflows from free catchment, the catchment
rainfall has been worked out using Theissen Polygon Method and tabulated in
Annexure-11.Since observed flows at Sardaput G&D Station include the spill flows
from adjoining catchment of Indrāvati and interrupted flows from UKD, for which
long term proper record is not available to segregate the flow from free
catchment,rainfall in the catchment has been compared with that in UKD’s catchment
for the concurrent period of 1972-73 to 1998-99, average monsoon rainfall during this
period in the two catchments, are 1225.25 mm and 1200.71 mm respectively. Values
of average annual rainfall for these CAs are however slightly more different. Since the
monsoon rainfall is the major source of surface runoff, and the two catchments having
similar topography,the monthly flows from the catchment have been estimatedon
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-5: Hydrology 5-26
catchment area proportionate basis shown in Annexure – 12and the inflow from the
catchment of Kasbal-Moulijodi Nallah has been added and the flow series derivedthus
aretabulated in Annexure-13. The final water availability at the barrage site has been
worked out after addition of overflows and tail water release to beworked out after
simulation of balancing reservoir.
5.7 DESIGN FLOOD
Estimation of design flood for design of structures is a very significant component of
hydrological studies from safety point of view. Besides safety of the structure, the
decision in respect of magnitude of design flood to be adopted is based on potential
damage in the valley in case of failure of the structure.
5.7.1 Design Flood Criterion
Since absolute flood safety is unrealistic, selection of proper rational flood is very
important in view of the reason that the higher value of design flood will result in
uneconomical cost of the project whereas the lower value increases the risk of safety
of structure and the protection of population. Further, the decisive factor in
determination of design flood is the feature or parameter of flood that can be
identified as the major cause of potential damage. The decision as to which parameter
should be considered for particular case rests with the planner and the designer and
should be based on the analysis of the given situation. The decisive parameters
(WMO, 1994) as given in the Table-11may be used for guidance:
TABLE-11

4 Cases where superimposition of several
floods must be considered i.e. flood

tributaries or for reservoir operation
during flood
Flood hydrograph shape
5.7.2 Design Flood Criteria For Weir / Barrage
Weir and barrage which are diversion structures have generally small storage
capacities and there is rarely any enhanced risk of life and property d/s due to failure
of structure. However, apart from loss / damage of structure, there will be disruption
of irrigation and communications which are dependent on the structure. Existing
practices for adopting design flood of barrages and weirs are as per recommendation
of the BIS Code IS: 6966 Part-I “Hydraulic Design of Barrage and Weirs-Guidelines
Alluvial Reaches”, which states that for design of such structures, design flood of 50
years return period may normally suffice. But in such cases, where risk and hazards
are involved, a review of the criteria based on site conditions may be necessary. For
deciding the freeboard, a minimum of 500 years return flood or the standard project
flood may be desirable.
5.7.3 Design Flood Criteria For Storage Dam
Inflow design flood for the safety of dam is the flood for which, when used with
standard specification, the performance of the dam should be safe against
overtopping, structural failure, and the spillway with its energy dissipation
arrangements should function reasonably well.
The criteria for fixing spillway capacity of storage dams as prevalent in India are
covered in IS: - 11223 -1985 “ Guidelines for fixing spillway capacity, which states
that the inflow design flood for the safety of dam would be selected on the basis of the
classification of the dam as follows:
TABLE -12
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-5: Hydrology 5-28
Classification of dam and the design flood to be adopted
Classification Gross storage (Mm3) Hydraulic Head (m) Design Flood
Small Between 0.5 and 10 Between 7.5 and 12 100 year flood
Intermediate Between 10 and 60 Between 12 and 30 SPF
Large Greater than 60 Greater than 30 PMF
Hydraulic head is measured from minimum tail water level to the full reservoir level
and the classification adopted would be the greater of that indicated by the above two
parameters. Floods of higher or lower magnitude can be considered if the hazards
involved in the eventuality of a failure, is particularly high or low. Any departure
from general criteria as above on account of larger or smaller hazard should be clearly
brought out and recorded.
5.7.4 Estimation Of Design Flood For Diversion Structures In Middle Kolab Project
As may be seen from the sketch showing layout of the Middle Kolab Project, three
number of major structures as mentioned below are proposed across the main stream,
and the local streams intercepted by the link canal.
i) A barrage at Dumajodi across river Kolab to divert water to link canal
ii) A storage dam across the local stream known as Kerajodi Nallah to act as
balancing reservoir for the Middle Kolab Hydel Power house at Kodukugarha
iii) A barrage across river Kolab , downstream of Kerajodi’s confluence with Kolab
Depending upon the size and type of the structures, the design floods of appropriate
magnitude indicated in the table below as per codal practice stated in Para above,
have been calculated for individual structure.

For estimation of design floods, hydro-meteorological approach has been
adopted.Accordingly the values of design storm in the catchment corresponding to the
design flood of individual structure with different return periods have been worked
out as discussed in the forgoing Para.
5.7.5 Estimation Of Design Storm & Its Temporal Distribution
The two barrages on the Kolab river and the one dam on its tributaries if having
heights over 30 meters, are to be designed for Probable Maximum Flood (PMF) as per
criteria laid down for High dams in relevant BIS code. Their PMF has to be a flood
corresponding to Probable Maximum Storm resulting from the most critical
combination of meteorological conditions resulting in the highest rainfall. It is equal
to the highest observed storm depth transposable over the project region called
Standard Project depth adjusted for the maximum moisture charge.
The catchment areas of the three structures are prone to severe rainfall of
unprecedented magnitude under the influence of monsoon systems originating from
the Bay of Bengal and the cumulative effect of orographic features of the Eastern
Ghats and the systems in upper air easterlies.
Accordingly severe storms over Orissa were studied and it transpired that 28 – 29
August 1982 storm centered over Bijepur is the severe most storm and also
transposable over the project catchment owing to climatic and geographical
homogeneity of the storm region and the project region.
The project catchment is rectangular one with catchment areas of 3103 sq km up
toDumajodi Barrage and elongation ratio of about 2.0 and resembles the core isohyets
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-5: Hydrology 5-30
of the storm. PMP depth for 1-day duration on transposition over the project
catchment area is estimated as below:-
i) At the barrage over Kolab near Dumajori village, downstream the confluence of
Joura Nallah which delivers Indrāvati river spills into the Kolab
ii) When the core of isohyets including the severe most storm center lies above the
Upper Kolab Dam:
Maximum Transposed depth above Upper Kolab: 434 mm
MMF = 1.34, PMP: 1.34 X 434 = 582 mm
Clock hr correction factor = 1.15 limited to 50 mm= 50 mm
24 hour PMP depth: 632 mm
Corresponding storm depth between Upper Kolab and Dumajori
Storm depth = 201.5 mm
MMF = 1.34
Maximized depth: 270 mm
Clock hr Factor : 1.15
Therefore 24 hr depth: 310 mm
iii) When the storm is concentrated between the Upper Kolab and the diversion
Barrage
Maximum Transposed depth below Upper Kolab: 446.6 mm
MMF = 1.34, PMP: 1.34 X 446.6 = 598 mm
Clock hr correction factor = 1.15 limited to 50 mm= 50 mm
24 hour PMP depth: 648 mm
Corresponding storm depth above Upper Kolab and 1st Barrage:
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-5: Hydrology 5-31
Storm depth = 372.55mm
MMF = 1.34
Maximized depth: 499 mm
Clock hr Factor : 1.15 limited to 50mm: 50 mm
Therefore 24 hr depth: 550 mm
The above depths are, therefore, adapted as the Probable maximum storm depths.
II) Dam over Kerajodi Nallah (Balancing Reservoir)
The drainage area of the dam is less than 50 sq km, maximum observed point rainfall
of 521mm recorded at Bijepur during the 1982 storm is proposed to be adopted with
1.34 moisture maximization factor and 50mm towards clock hour correction. The
final 24- hour point PMP depth is estimated to be 748mm.
III) Second/Irrigation barrage over the Kolab
The total catchment area including all upstream structures is about 1227sq km
including Kasbal-Maulajodi catchment. Storm depths estimated as in the case of first
barrage is adopted as design storm for irrigation barrage in Kolab.
Temporal Distribution
Based on self recording rainfall data of nine rain gauge stations at Manoharpur,
Brahamapuri, Kanker, Khilari, Palkot, Ranchi,Tillaya, Keonjergarh and Khirawan in
the storm region following temporal distribution is recommended.

5.7.6 Estimation of Design Flood for Diversion Barrage at Dumajodi
As mentionedabove, a barrage atDumajodi has been decided as the diversion structure
across Kolab Riverto divert its water in to the link canal. As per codal practice for
design flood criteria explained in Para above, a flood peak corresponding to 50 years
return period as design flood will suffice. For deciding the free board, flood peak
corresponding to 500 year return period or SPF has been considered.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-5: Hydrology 5-32
In order to estimate the design flood of desired magnitude, the corresponding design
storm in the catchment has been worked out as discussed earlier by transposing storm
over the catchment with its centre located suitably to produce maximum influence.
Since, the catchment of Kolab river at Dumajodi is split into two parts by the existing
UKD, the inflow flood from the catchment upstream of UKD will get moderated
while routing through the reservoir and then through downstream course of Kolab.
Inflow flood from free catchment at Dumajodi below UKD will then be added to
moderated flood from catchment of UKD. Accordingly, the values of design storm in
the two parts of the catchment are tabulated as below
Table-14

100 year’s 24.84 20.31
SPS/ 500 year’s 49.66 42.84
Since, data related to the concurrent short interval rainfall and runoff in the catchment
are not available, synthetic catchment response function (UG) for the two parts of the
catchment have been developed as per “Flood Estimation Report for Lower Godavari
subzone (Subzone - 3f)” published by CWC. The UGs developed thus were
convoluted with corresponding design storm in respective catchment. Flood routing of
inflow floods from UKD’s catchment weredone through the UKD reservoir using
Modified Puls Method assuming critical condition of the reservoir i.e., the design
flood impinges when the reservoir is full upto FRL. This moderated flood was then
added to the inflow flood from free catchment after channel routing by Muskighum
method.The complete detail calculations are appended in Annexure-13(i to vi). The
design flood hydrographs of its catchment’s inflow floods with different return period
are plotted and shown in Fig.18 below.

Besides flood from its own catchment, the spill channel viz.Joura Nallah will import a
part of Indrāvati’s flood to Kolab, as it is an uncontrolled spill channel. To work out
the percentage flood discharge to be transferred by Joura Nallah, analysis of observed
flood discharges in Indrāvati river at Jagdalpur and Joura Nallah at Murthandi for the
concurrent period when the spill channel appears to have attained stability, has been
done and the result is tabulated below:

5.7.7 Estimation of design Flood of Kerajodi Nallah at Proposed Dam Site
A storage dam of approximate height of 94 m is proposed across Kerajodi Nallah at
the end of link canal to create a balancing reservoir with gross storage of about 135
MCM. As per codal practice, the design flood to the magnitude of PMF will be
required for design of the structure. The catchment area of Kerajodi Nallah at the
proposed dam site is 25.55 Sq.km. One-daypoint PMP of 748 mm has been
considered as the design storm, 24-hour PMP after applying clock hour correctionas
well as areal correction for the catchment works out as 688.1mm. The catchment
response function (UG) has been developed as per CWC’s publication mentioned
above. The UG was convoluted with one-day PMP as in Annexure-15 and the plot of
design flood hydrograph for different return period is shown in Fig-21 below.

5.7.8 Estimation of design Flood of Kolab river at Irrigation Barrage Site
As may be seen from the line sketch of schematic layout of the project, a barrage is
proposed across river Kolab at a suitable location below the confluence of Kerajodi
Nallah to divert water for irrigation to about 25,000 ha of cultivable land in Maithili
block of Malkangiri dist. As per codal practice for design flood criteria explained
above, a flood peak corresponding to 50-yr or 100-yr return period as design flood as
the case may be, in view of downstream situation have been considered. For
deciding the free board, flood peak corresponding to 500 year return period or SPF
has been considered.
Since, the catchment of Kolab River upstream of proposed diversion structure is likely
to be intercepted by a number of structures after construction of the project, 50& 100
year’s return period flood at the proposed site has been worked out after accounting
for the moderation effect by each structure. The catchment response function (UG) for
the free catchment of Kolab below Dumajodi has been developed as per CWC’s
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-5: Hydrology 5-38
publication mentioned above. The UG has been convoluted with SPS and 100, 50 and
25 year’s return period design storm of 16 hour duration in the catchment. The return
period flood and SPF from the intercepted catchment after routing through the
reservoirs as the case may be, and the downstream reach of the channel, have been
added to the correspondingreturn period flood and SPF from free catchment.
The flood peak of 50-yr’s and 100 – yr’s return period from catchment of Kolab thus
works out as 8084Cumec and 9793 cumec respectively. These values of flood peak
however do not include the effect of flood spill from Indrāvati through Joura Nallah.
The peak value of flood spill corresponding to50-year’s and 100- yr’s return period
works out as 1266 cumecs and 1391 cumec respectively. The design flood peak after
summation of effect of flood spill thus works out as 9350cumecand11184cumecand
can be considered for hydraulic design of the barrage as the case may be. On the
similar line, SPFhave been calculated, details of which are appended at Annexure-16.
Plot of final flood hydrographs after routing through the reservoir and channel is
shown Fig-23 below.

5.8 DIVERSION FLOOD FOR PROPOSED STRUCTURES DURING
CONSTRUCTION
Considering that the construction activities for the project will be carried out even
during the monsoon season to complete the project in short period, the 25 year and 50
year return period flood corresponding to monsoon period have been selected as
design flood for temporary diversion structure to be constructed during construction
period. Thus, the design flood for the different structures have been worked out hydro
meteorologically as discussed in the last para corresponding to these return periods.
The flood peaks for the different structures are tabulated below:
Sl no Structures 25-Yr’s return

3 Irrigation barrage 6819 cumec 8084 cumec
Corresponding to above return period, the risk factors for various probable
construction periods say 5 years, 8 years and 10 years have been worked out using the
following relationship:
Risk = 1-Pr (Non exceedance)
= 1-(1-1/Tr)n
Where Tr = Return period for which design flood is considered
n = Construction period in years

design flood for construction of diversion structure keeping in view the probable
construction period and risk factor.
5.9 RESERVOIR SEDIMENTATION
It is well known that life of the reservoir is very much affected by sedimentation.
Therefore, it is very necessary that the capacity lost in the reservoir due to
sedimentation during its life is accounted properly. As per the criteria laid down in the
guideline of the working group report for hydel project, usually 25 years of reservoir
sedimentation is considered for revised Elevation Area Capacity curve for use in the
stimulation study. The outlet sill level of the reservoir is kept well above the 70 year
New Zero Elevation (NZE). The procedure discussed in CBIP publication No 19 “life
of the reservoir” is used for obtaining the New Zero Elevation expected after 25 yr
and 70yr sedimentation and the revised Elevation-Area-Capacity curves. BIS Code
12182 -1987alsostipulates that the feasibility service period of 70 years and a full
service period of 25 years can be considered in case of power projects supplying
power to grid. The 70 year sediment load, and the new zero elevation has been used
for fixing power outlets and MDDL of the reservoir. The 25 year revised area
capacity curves for reservoir would be used in the simulation/ working table studies.
Water from upper Kolab catchment will be available after routing through the upper
Kolab reservoir, an average area-capacity curve after 25 yr. of sedimentation is
required for the simulation studies. Accordingly the sedimentation study using
empirical area reduction method has been carried out assuming the sediment rate of
0.43 mm/yr as adopted in the UKD Project report & used for working out the balance
water available for Middle Kolab Project after meeting the irrigation requirement in
Satiguda Irrigation Project.
The Middle Kolab Catchment is a part of the Kolab catchment, the project being
located just downstream of upper Kolab dam projects, where thesediment inflow rate
is70 Ha.m/yr, the same has been adopted in view of the topographical similarity.
Since in Kerajodi reservoir the ratio of expected average annual volume of sediment
deposition and gross capacity of the reservoir works out as 0.24, the sediment
problem is significant. The calculations for sediment distribution to calculate the
revised area for the reservoirs andits capacities after 25 years and 70 years of
operation are shown in Annexure -17.2 & 17.3.

6.0 GENERAL
The Middle Kolab Multipurpose Project envisages two barrages on River Kolab and
an earthen dam at Kerajodi Nallah. There is one diversion barrage near village
Chhatarala in Koraput District. The overall waterway is 177 m long. This barrage
diverts the water through a 38.55 km long link channel to the reservoir of an earthen
dam 678.88 m long, on Kerajodi Nallah. Water from the dam is taken through HRT to
the proposed powerhouse and then again back to river Kolab. There is another barrage
(Irrigation Barrage) on river Kolab, near village Tentuliguda. The overall waterway of
this barrage is 237 m. Two unlined canals – Right Main Canal (RMC) and Left Main
Canal (LMC) are being proposed to take off from the irrigation barrage, on the right

discharge through steep sloped open channel, called chute placed either along a dam
abutment or through a saddle. It is provided mainly with an earthen dam or a rockfill
dam & is isolated from the main dam.
The spillway is designed so as to pass the maximum discharge of 1160 cumecs, .i.e.
PMF flood. The spillway is designed for discharge corresponding to the reservoir
level at 528 m i.e. at FRL. It is proposed to keep 5 nos. of bays of width 9 m each and
4 nos. of piers. The piers are needed to hold the sides of the gates in gated spillways.
The function of the piers is to contract the flow and, hence to alter the effective crest
length of the spillways, in addition to provide support. The effective length of the
crest is expressed as:
Le = L - 2 (N*Kp + Ka) Hd
Where,
L = Clear length of the crest;
Kp = Pier contraction coefficient is equal to 0.01 for round nosed pier;
N = Number of piers;

offtaking from the canals and having discharge less than 1 cumec have been designed
as lined canals with trapezoidal sections having side slopes of 1.5(H) : 1 (V) for
precast concrete lining. Trapezoidal canal section is adopted for practicability and the
canal has been designed by Manning’s formula.
Three types of cross sections have been adopted as below
1. Canal in full cutting
2. Canal in partial cutting & partial filling
3. Canal in complete filling.
Side slope in cutting and filling is taken as 1:1 and 1.5:1 respectively depending upon
the type of the soil. Outer slope of the bank has been provided as 1.5:1. A freeboard of

R = Hydraulic mean depth = A / P in meter.
A = Sectional area of canal with side slope 0.5:1, in square metre.
P = Wetted perimeter in metre.
S = Bed slope /water surface slope
N = Coefficient of Rugosity
The following criteria have also to be kept in view while designing the irrigationchannels
a) Water Surface Slope
It should be between 1:10,000 to 3,000 i.e. for Main Canal it is proposed as
1:5000 and for other channel, it is proposed as 1:3,000. I f the gradient is steep,
falls / drops are to be provided where the Canal Full Supply level touches the
ground level.
b) Bed Depth Ratio (B/D Ratio)
The B/D Ratio should normally vary between 1.20 to 3.00 to adopt the most
economical design section.
c) Conveyance Losses
The conveyance losses to be adopted 2.25 cumecs / million sq. m. of wetted are in
case of unlined canals and 0.60 cumecs/ Million Sq. m. for lined canals.
d) Water Allocation (Duty)
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-6: Project Design Features 6-8
The water allocation (Duty) is to be taken as 650 ha. of C.C.A. / cumec
(1.538liters per sec per hectare) including all losses for this project area.
e) Rugosity Co-efficient
The following values of rugosity co-efficient (n) are to be adopted in design of canal
system for channel with pre cast concrete lining 0.017, for earthen channel 0.0225, and
for channels in gravels and cobbles 0.03.
The design of section for Link channel, Left Main Canal and Right Main Canal are
given as Annexure-6.8. Typical sections of unlined canal for all are shown in drawing
No WAP/WRD/MKMP/10 in the drawing volume.
The L-sections of the Link Channel, Left Main Canal and Right Main Canal are also
given in the Drawing Volume as drawing no. WAP/WRD/MKMP/12, 13 and 14
respectively.
6.2.9 Design of Civil Structures
a) Cross Drainage Works
Whenever a canal crosses a natural drainage on its way, it is necessary to construct
hydraulic structure to dispose off drainage discharge, so that water supply continues
uninterrupted. These pukka works are termed as cross drainage works. Canals, which
are aligned as contour channels, cross largest number of natural nallah or drains.
Cross Drainage works are thus unavoidable on any canal system. These include
aqueducts, drainage syphons, super passages, drainage under tunnel and canal siphon,
falls, inlets, outlets and diversion works.
Drainage water interrupted by a canal may be disposed off
i. By passing the canal over the drainage and is achieved through aqueduct
ii. By passing the drainage over the canal and is achieved through a supper
passage
iii. By lowering the canal/drainage and is achieved through either drainage
siphon or drainage under tunnel.
Falls are provided where the existing ground slope is steeper than the longitudinal
slope provided. Vertical falls are provided in the distributaries, minors, sub minors
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-6: Project Design Features 6-9
and water courses. Locations of falls are normally made where the FSL meets the
ground level. To dissipate the excess energy developed, a cushion has been provided
in the downstream.
On the Right Bank canal there are Syphon and Aqueducts, including minor canals and
natural drains while on the Left Bank Canal there are Aqueducts, syphons. The
Typical designs of cross drainage works on the Right Bank Canal like Syphon,
Aqueduct are prepared and details are enclosed in drawing no.

be provided at suitable intervals for roads, village cart tracks etc. These structures are
provided as Village Road Bridge, Major District Road Bridge, depending upon the
type of the road. Bridges in the canal system are provided based on the type of roads.
It crosses i.e. village road, district road, state highway or National highway. The
bridges are combined with irrigation structures like falls or regulators. All the bridges
across canals are designed according to IRC specifications/loadings. These are now

a) Macro-Canalization Planning
The command area of the project lying on both sides of the river Kolab is proposed to
be served by construction of two canals- one on each side i.e. Right Main canal and
Left Main canal . Distribution systems such as minors/sub minors are also proposed to
off take from both canals in order to serve the separate pockets of command. Their
design criteria have already been outlined in previous para.
Micro –irrigation system operation and criteria for fixing the level of out-let/ off-
taking channels are described as under:
In order to achieve the utilization of full irrigation potential created under any
irrigation system, it is necessary that net-work of well aligned field channels/water
courses is laid, so that the beneficiaries get their allocated water at specified time. The
criteria for fixing the level of outlets and off-taking channels are enumerated below:
i. The level of the field proposed to be irrigated will determine the water level
required at the head of water courses
ii. It should be seen that F.S.L in the irrigation channel does not rise unnecessarily
high in an attempt to command isolated high patches, nor it would be lowered
too much at the cost of sizeable command.
iii. Head over Field 0.15 to 0.3 m depending on the conditions obtaining in each
canal
iv. Minimum working head at outlets 0.15 m.
v. The distribution systems are designed in a way so that they are able to draw full
designed discharge when the main canal is running at the designed F.S.D. This
would mean that F.S.L of the distribution system will be fixed 0.15m lower than
the F.S.D of the main canal
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-6: Project Design Features 6-12
vi. Minimum driving head of 0.15 m adopted from Main canal to minors and from
minor to sub minors.
b) Drainage Network Planning
Micro Canalization comprises the irrigation network below the outlet upto
cultivated fields. The drainage network system is to be planned considering the entire
chak as unit and the entire water of the chak is being drained to the lowest point of the
chak by means of firm drains. The firm drains are to be constructed and maintained by
the farmers. The water so collected is planned to be disposed off to the natural nallah,
drain or river means of link or outfall drains and are defined as follows:
Link drain is one which collects water from the chak through an inlet structure and
leads upto the outfall drain i.e. outfall to the outfall drain. Outfall drain is one which
collects water from the chaks as well as from link drains and leads upto the natural -
nallah, drain or river for disposal.
Inlet structures have been provided where the water of the chak enters the link or
outfall drain and outfall structures have been provided where link drain meets with the
outfall drain or meets with the natural nallah, river. At the outfall point, a minimum
H.F.L difference of 0.10m has been provided for effective drainage.
c) Micro Planning
An area of 1189 ha out of 9633 ha, i.e., 12.3% of the total command area of the
project has been considered as pilot area from Right Main Canal (RMC) for macro &
micro canalization of the Project. Minors, sub minors, watercourses, field channels
including link & outfall drains were planned in the pilot area considering the
guidelines in view for network planning
Minor having a discharge of less than 1 cumec have been designed as lined
trapezoidal canals with bed slope of 1 in 3000, Rugosity coefficient of 0.017, free
board of 0.5 m is considered. Side slopes of 1.5: 1 is taken while designing the canal
sections. A CCA of 1189 ha was considered for planning of the 12.3 % of pilot area.
A duty of 650 ha/cumec is been utilized at arriving the discharges for minors & sub
minors including all losses.

CHAPTER – 7
IRRIGATION PLANNING
7.1 INTRODUCTION
Odisha state is having predominantly agrarian economy with nearly 25%
contribution from agriculture in net state domestic product. About 73% of total
work force is engaged in farming sector. Gross cropped area in the state is about
90.09 lakh hectares out of which only 33.08 lakh hectares (36.72%) is irrigated.
Climate in the state is quite variable and plays major role in agriculture economy of
the state. About 37% of total geographical area of the state is occupied by farming.
At the time of independence total food production in the state was estimated at 24
lakh MT which has increased to 92 lakh MT in 2007-08. Thus, Odisha state
contributes around 4% in national food production. Paddy is most important crop
in the state occupies about 60% of gross cropped area with average productivity of
about 1.7 ton/ha as against 2.1 ton/ha at national level. Food crops occupy almost
90% of gross cropped area which is mostly raised (62%). The use of improved
seed, fertilizers and pesticides are also much lower than the national level.
Cultivable land of the state can be divided into high lands (47%), medium (28.5%)
and low lands (24.5%).
Odisha state is characterized with subtropical climate with high temperature, high
humidity, medium to high rainfall and short winters. Average rainfall is about 1450
mm out of which about 80% is received from June to September and remaining
20% in winter months. The state suffers from natural calamities like floods,
droughts and cyclones almost every year.
Odisha state is having abundant water resources and extensive network of rivers
and streams. For judicious utilization of water resources, it is essential to have
proper infrastructure for conservation and management of water resources in the
state.
Water is essential input for plant growth and development. Full potential of crop
varieties can be exploited when water is not limiting. Several irrigation projects are
being implemented to augment irrigation potential in the state. By 2008 about
40.81 lakh hectare of irrigation potential has been created using surface and ground
Middle Kolab Multi-Purpose Project Detailed Project Report
Chapter-7: Irrigation Planning 7-2
water in the state.
At present about 33.08 lakh hectare area is irrigated which accounts to 81 % of
total irrigable area and about 36 % of gross cropped area. Major sources of
irrigation are ground water resources, lift and flow irrigation systems.
7.2 AGRO-CLIMATE
The State can be divided into ten agro-climatic zones on the basis of soil, weather
and other relevant characteristics. Its land can be classified into three categories,
low (24.5%), medium (28.5%) and up-lands (47%) with various types of soil like
red, yellow, red-loamy, alluvial, coastal alluvial, laterite and black soil etc. with
low and medium texture. Characteristics of different agro-climatic zones in Odisha
are presented in Table.

The command area of Middle Kolab Multipurpose Project lies in Malakangiri
district of Odisha, which falls under semi-arid region which receives average
rainfall of 1597 mm per annum. Out of total rainfall, about 75-80 percent is
received during rainy season from June to September. The remaining 20-25%
rainfall is received in winter and summer months.
The project area is located in Koraput district. The minimum and maximum
temperature ranges from 12oC to 40oC.
It is seen that relative humidity is maximum in the month of August and minimum
in the month of March. The relative humidity in the basin varies from 88% to 93%
during July to September.
There are three distinct cropping seasons namely, Kharif, Rabi and Zaid. Kharif
season starts with onset of south-west monsoon in the month of June and
terminates in September-October. The crops are grown mainly as rain fed in Kharif
Middle Kolab Multi-Purpose Project Detailed Project Report
Chapter-7: Irrigation Planning 7-4
season. Owing to limited irrigation facilities Kharif is the main cropping season in
this region. Productivity of Kharif crops depends on timely rain and its distribution
in the season. The sowing of Kharif crops is mostly done in June- July but it
continues up to August in some cases. Kharif crops are harvested in October-
November. The sowing of Rabi crops starts in November as soon as the fields are
vacated from Kharif crops and continues till late December. Rabi crops are
harvested by April. In Zaid season, crops can be grown with assured irrigation
facilities. Short duration crops like Urad, mung or maize can be grown from
February to May-June. Some crops like paddy, maize, sorghum, vegetables etc. can
be grown throughout the year with assured irrigation.
7.3 EXISTING CROPPING PATTERN
In Malkangiri district, among cereals rice is principal crop occupying about 92.9
thousand hectares in kharif and 900 hectares in rabi season. In rabi season rice is
gross as irrigated while in kharif season about 55% area is rainfed. Coarse cereals
like maize and ragi, small millets like bajra and jawar are also grown in limited
areas.
Pulse crops like arhar, gram, urad and mung are grown with residual moisture
under rice-fallow rotation. The productivity of these crops is low mainly due to
conventional method of cultivation. Pulses occupy about 6000 ha area.
Major oilseed crops include ground nut, sesame, linseed, sactor, mustard,
sunflower, riger and safflower. These crops occupy about 30 thousand ha area in
the state. Oilseed crops are grown in uplands in Kharif and river beds and rice
fallow in Rabi. Most of the oilseeds expect ground nut have quite low productivity.
Low input application is the main reason for low yield of oilseed crops. Pulses and
oilseeds are mostly used for home consumption and very little surplus is available
for market.
Jute, mesta and cotton are important fibre crops occupying very limited area in the
distirict. The area of jute and mesta is shrinking due to availability of synthetic
fibre.
Cultivation of sugarcane is also gaining cash popularity due to establishment of
sugar mills in the state. Cash crops are being cultivated in about 2% of the total
Middle Kolab Multi-Purpose Project Detailed Project Report
Chapter-7: Irrigation Planning 7-5
cultivable area. Vegetables are also being grown in substantial area. Very limited
area is also occupied by fruits namely mango (7200 ha), citrus (700 ha), papaya (50
ha) and banana (500 ha). About 100 ha is occupied by spices.
7.4 IRRIGATION COMMAND
The water from the Kolab river will be diverted through a diversion barrage
constructed just downstream of the confluence of Joura Nallah and Kolab River,
which will be used to augment the water availability for the dam to be built on
Kerajodi Nallah. The water from reservoir will be carried through Power House
located at lower altitude on the left side of Kolab River near village Kodukugurah
in Odisha. The water finally released from power house back to Kolab River. An
irrigation barrage will be constructed in further downstream to envisage irrigation
to CCA of 24543 ha. Two canals, one with length of 77.1 Km (to the left bank of
Kolab River) and another with 27.4 Km (to the right bank of the Kolab River) will
take off from this Barrage. A schematic diagram (Index Map), showing the
command area and the location of Dam & Barrages, are given in Dwg. No.
WAP/WRD/MKP/INDEX MAP.
7.5 PROPOSED CROPPING PATTERN
The cropping pattern in a private area is influenced by prevailing climate
conditions like rainfall, temperature, and humidity and sunshine hours. In addition
soil fertility, topography and moisture status also affects selection of crops in a
particular season. Supply of agricultural inputs like seed, fertilizer, water and
pesticides also plays an important role in selection and success of a particular crop.
Development of infrastructure for irrigation can bring about significant changes in
cropping pattern.
At present Kharif crops occupy more than 70% of gross cropped area as these
crops can be grown as rainfed in rainy season. In Rabi season water becomes
limiting factor and crops can be grown only where irrigation is available. There are
some pulses and oilseed crops which can be grown in Rabi season with limited soil
moisture but their productivity is quite low. At present cropping in project area is
less than 80% which can easily be raised to 160% with availability of irrigation in
Middle Kolab Multi-Purpose Project Detailed Project Report
Chapter-7: Irrigation Planning 7-6
Rabi season. Some short duration crop like vegetables can also be incorporated into
cropping system with irrigation.
The cropping pattern in a particular area is governed by its climate including
maximum and minimum temperature, rainfall and its distribution, soil type and
topography, availability of irrigation facilities, supply of agricultural inputs and
capacity of farmers to buy them, and ultimately marketing support to the
agricultural produce associated with its demand. The availability of irrigation water
through this project is likely to bring perceptible change in existing crop scenario
in the district.
At present, rice occupies more than 70% cropped area in Kharif season and another
13% area in Rabi season. During Kharif season rice is mainly grown as rainfed
crop and it does not make use of irrigation water. But in Rabi season rice is grown
as irrigated crop. Rice having higher water requirement than other crops utilizes
sizable amount of irrigation water which can other wise be used to grow other
crops like pulses oil seeds and cash crops including vegetables, fruits and spices in
much larger area. Thus, if rice crop is replaced by more remunerative crops in Rabi
season like vegetables, fruits, pulses and oilseeds, it can fetch a better price and
bring about prosperity to the farmers in the district. It is therefore suggested that
rice cultivation may be restricted to Kharif season and replaced by other crops in
Rabi season with lesser water requirements. For instance, Maize can replace rice in
Rabi season. Pulse production in Rabi season can be increased by about 5%, if 5 to
6% area occupied by rice in Rabi season is spared.
Among vegetables/spices occupies 1% area in Kharif. Its area may be readjusted
and other vegetables, fruits and spice crops may be introduced with availability of
irrigation facilities. Sugarcane is other cash crops grown on very limited scale. Its
needs a closer look to decide their area under changed conditions keeping
economic considerations in view.
Flower cultivation can also be taken on small scale to start with and extended later
depending upon demand and market support. Flowers like marigold, gladiolus, rose
etc can be grown where irrigation facilities are available. It may have scope near
cities particularly in festival season.

7.6 ASSESSMENT OF CROP WATER REQUIREMENTS
Crop water requirement is defined as the depth of water needed to meet the water
loss through evapotranspiration of crop growing in large fields under non-
restricting soils, water and nutrient availability and achieving full production
potential under the given growing environment. The success of this objective
depends on matching the water availability at river source with the quantum of
water required for various crops in the command area for sustainable agricultural
production. In the present study, procedure adopted for calculation of crop water
Middle Kolab Multi-Purpose Project Detailed Project Report
Chapter-7: Irrigation Planning 7-8
requirements and irrigation requirements are mainly based on methodologies
presented in FAO Irrigation and Drainage papers No. 24 “Crop Water
Requirements” and No. 33 “Yield response to water” The software “CROPWAT
5.7” based on revised method for estimating reference crop evapotransipiration,
adopting the approach of Penman-Monteith as recommended by the FAO Expert
consultation held in 1990 in Rome has been used for calculation ETo and crop
water requirements for the selected crops.
Efficient use of water in crop production can only be attained when the planning,
design and operation of water supply and distribution system is geared towards
meeting requirements in quantity and time during the periods of water shortage, for
optimum and high yields of crops. For effective application in planning, design and
operation of irrigation system, it is necessary to analyse the effect of water supply
on growth of crops. The relationship between crop yield and water supply can be
evaluated when crop water requirements and crop water deficits on one hand and
maximum and actual crop yield on the other can be quantified. Deficit in water and
the resulting water stress on the plant, have an effect on crop evapotranspiration
and crop yield.
The following are the main factors which play an important role in determining
crop water requirements.
a) Climate or the ambient environment enveloping the plant determines the
evaporative demand. For instance, in sunny and hot climate, crops need more
water per day than in cloudy and cool climate,
b) Crops like banana and sugarcane having large leaf area need more water than
crops having smaller leaf area like beans and wheat,
c) The crops which are fully grown need more water than crops that have just
been planted and
d) On the whole, surface climatology including temperature, sunshine duration,
wind velocity, relative humidity and rainfall has a substantial effect.
7.6.1 Step-by-Step Procedure for Computing Crop Water Requirement
There are several methods for computing crop water requirements using
climatological and physiological approaches. The most practical and
comprehensive method for computing crop water requirements based on
Middle Kolab Multi-Purpose Project Detailed Project Report
Chapter-7: Irrigation Planning 7-9
climatological approach is “Modified Penman’s method”, which has been used to
compute crop water requirements for this project. The step-by-step procedure for
computing crop water requirement is summarized below:
Modified Penman’s Method
Based on the studies of the climate and measured grass evapo-transpiration data
from various research stations in the world, Dooven bas and Pruitt (1977) proposed
method known as modified Penman’s method for estimating reference crop
evapotransipiration (ETo) and gave tables for computations.
The procedure for computing crop water requirements is summarized below:
(1) Collection of climatologically data.
(2) Computation of reference evapotransipiration (ETo) based on two
components viz: radiation term and aero dynamic term.
(3) Selection of crop coefficient Kc
(4) Determination of effective rain fall.
(5) Computation of crop water requirements and irrigation requirements for the
proposed cropping pattern.
i) Collection of Climatologically Data
Crop water requirement is basically influenced by surface climatological data
including temperature, sunshine duration, wind velocity, relative humidity and
rainfall. It may be worthwhile to mention here that variation of climatological
parameters such as sunshine hour, relative humidity, maximum and minimum
temperature over the area is much less than variation rainfall. The Middle Kolab
Multipurpose Project command has two canal from the Irrigation Barrage, (i) right
main canal with CCA of 9391 hectares and (ii) left main canal irrigating CCA of
15152 hectares in Malkangiri district. For the present study, the climatological data
of Climatological Station, Koraput having Latitude of 18° - 49’ N, Longitude 82° -
43’ E and elevation of 913 m above MSL was used. However, for rainfall the data
of various stations falling within the project command were considered for finding
out the 75% dependable rainfall. It is to be noted that the rainfall significantly
influences the irrigation requirements.
Middle Kolab Multi-Purpose Project Detailed Project Report
Chapter-7: Irrigation Planning 7-10
ii) Computation of Reference Evapo-transpiration (ETo)
The crop water requirement (ETc) is calculated using following relation
ETC = ETO x KC
Where,
ETC = Crop evapo-transpiration, mm/day.
Actually ETC is defined as crop water requirement or consumptive use of crop
which is defined as the depth of water needed to meet the water loss through
evapotransipiration (ET crop) of a disease-free crop, growing in large fields under
non-restricting soil conditions including soil water, fertility and achieving full
production potential under the given growing environment.
ETo = Reference crop evapotransipiration in mm/day.
ETO represents the rate of evapotransipiration from an extended surface of 8 to 15
cm, green grass cover, actively growing, completely shading the ground and not
short of water.
KC = Crop co-efficient which varies with the crop genotype and growth stages.
More explicitly it is the function of crop canopy coverage. The KC of crop at
younger age is lower than that at full maturity stage.
iii) Selection of KC Values
The crop coefficient is the ratio of ETC/ETO. Whereas ETC is the crop
evapotransipiration of a crop and ETO is the reference evapotransipiration of grass
crop.
KC is defined as the canopy coverage factor, which is influenced by following
factors:
(i) Type of crop,
(ii) Growth stage of the crop,
(iii) Climate, and
(iv) Surface moisture condition of the field
With respect to type of crop the KC values of fully developed with large leaf area
of a crop like banana are higher than the KC values of fully developed with its
small leaf area such as gram crop. In fact the KC values are directly related to
Middle Kolab Multi-Purpose Project Detailed Project Report
Chapter-7: Irrigation Planning 7-11
extent of transpiration. KC value also differs with growth stage of a crop. For
instance the KC values of initial growth stage are much smaller than that of a full
grown crop. The climate influences the duration of the total growing period and
various growth stages. For example, in a cool climate, certain crop will grow
slower than in warm climate.
The crop factor KC is determined from following parameters:
(i) Crop genotype i.e. type of crop as cereal, vegetables, pulses, fiber crop etc.
(ii) The total growing period of each crop
(iii)Crop growth stages
The total growing period of a crop has been divided into four growth stages:
1. The initial growth stage: this is the period from sowing or transplanting when
the crop covers about 10% of the ground.
2. The crop development stage: this period starts at the end of the initial
growth stage and lasts until the full ground cover has been reached (ground
cover about 70-80%).
3. The mid-season stage: this period starts at the end of the crop development
stage and lasts until maturity; it includes flowering and grain-setting.
4. The late season stage: this period starts at the end of the mid season stage
and lasts until the last day of the harvest; it includes ripening.
In the present study the crop coefficient values for the crops under consideration as
recommended by FAO have been used and KC values interpolated for 10 daily
intervals are given in the tables containing crop evapotransipiration and irrigation
requirements data.
iv) Determining Effective Rainfall
The entire water received from rainfall is not utilized by the growing crop; a part of
it may be lost by surface runoff, deep percolation or evaporation. Only a portion of
heavy and high intensive rains can enter and be stored in the root zone. A part of
stored water is utilized by crop to meet its evapotransipiration. In the present study,
in the present “effective rainfall” has been computed using USBR method. The
monthly effective rainfall is given in Annexure-7.1
Middle Kolab Multi-Purpose Project Detailed Project Report
Chapter-7: Irrigation Planning 7-12
v) Irrigation Efficiencies
For the purpose of cropping pattern and crop water requirement the following
efficiencies are taken into consideration.

3. Field application efficiency 85% 77%

vi) Computation of Crop Water Requirements and Net Irrigation
Requirements
Crop water requirement (CWR) in practice are governed not only by the agro-
climatic conditions (temperature, humidity, wind velocity and bright sunshine
hours) and crop physiology i.e. crop coefficients (KC values) but also effective
rooting depth and soil moisture condition i.e. water depletion level affecting the
growth period. For design purposes, CWR is based on the assumption that no
restrictive conditions arising out of soil on water stress would apply. The ETC was
accordingly computed using KC factor values for particular crops and the ETO
values as computed by Penman – Monteith method. These are presented in
Annexure-7.1
For computing net irrigation requirement (NIR) effective rainfall using as
calculated by USBR method is accounted for and monthly net irrigation
requirement for various crops has been worked out and summarized in Annexure-
7.1. The summary gross requirement for 1000 ha of command area at plant root
and canal head is given in Table 7.1 (a). The detailed monthly net irrigation
requirements in mm for 1000 ha of command area for all the crops are summarized
in Table 7.1 (b). The gross irrigation requirements were determined for project

7.7 SOIL & LAND IRRIGABILITY CLASSIFACTION
On considering the local conditions of the Middle Kolab project areas, the
following soil properties are considered as class determining factors. These
include:
i) Effective soil cover (soil depth)
ii) Soil texture
iii) Water holding capacity
iv) Basic infiltration rate
v) Saturated hydraulic conductivity
vi) Soil drainability
vii) Soil erodability
viii) Electrical conductivity of saturation extract
ix) Exchangeable sodium percentage (ESP)
x) Macro land gradient and
xi) Rock out-crop
The critical limits of each above class determining factors will be based on the
requirement of the various crops to be grown in the area, cultural and social
practices adopted by the irrigators. The critical limits of class determining factors

CHAPTER-8
COMMAND AREA
8.1 GENERAL
Middle Kolabmultipurpose project is to be implemented in the district of Koraput
and command area of which lies in Malkangiri district in Odisha state. It is
envisaged that a CCA of 24543ha will be irrigated through two canal from the
Irrigation Barrage, (i) right main canal with CCA of 9391 hectares and (ii) left
main canal irrigating CCA of 15152 hectares in Malkangiri district.
Malkangiri district is located on a plateau having an area of 5791 sq. km and an
estimated population of 5,04,198. The inhabitants of the district are mainly tribal.
The literacy rate of the district is nearly 50%. Male to female ratio is round about
1000:997. The district is divided into 7 Tehsils and 7 blocks. Being close to tropic
of cancer, the district experiences tropical climate with warm and humid weather.
Frequent natural calamities like flood, drought, cyclone etc. are quite common.
Thus a cropping season is uncertain and variable.
Malkangiri district experiences three distinct weathers namely summer from March
to June, rainy season from July to September and winter from October to February.
District receives about 1700 mm annual average rainfall from south-west monsoon.
About 950mm rains are received from June to September and remaining in
October-November. The district experiences a long dry spell in winter and
summer.
Malkangiri district of Odisha is endowed with abundant water resources with
extensive network of rivers and streams. In spite of that only about 30% cropped
area is irrigated. Middle Kolab Multipurpose Project can create substantial
irrigation potential to cover more than 24500 ha of cropped area.
Total cultivable area is about 2,30,000 hectares which constitutes about 40 % of the
geographical area. In this total cultivable area about 1,36,000 hectares is under
single crop which is 59% of cultivable area and 23% of total geographical area.
Only 85,000 hectare is sown with second crop in a year. Total irrigated area is
estimated at 57,800 hectare accounting for 25 % of cultivable area.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-8: Command Area 8-2
8.2 PROPOSED CROPPING PATTERN
The cropping pattern in a private area is influenced by prevailing climate
conditions like rainfall, temperature, and humidity and sunshine hours. In addition
soil fertility, topography and moisture status also affects selection of crops in a
particular season. Supply of agricultural inputs like seed, fertilizer, water and
pesticides also plays an important role in selection and success of a particular crop.
Development of infrastructure for irrigation can bring about significant changes in
cropping pattern.
At present Kharif crops occupy more than 70% of gross cropped area as these
crops can be grown as rainfed in rainy season. In Rabi season water becomes
limiting factor and crops can be grown only where irrigation is available. There are
some pulses and oilseed crops which can be grown in Rabi season with limited soil
moisture but their productivity is quite low. At present cropping in project area is
less than 80% which can easily be raised to 160% with availability of irrigation in
Rabi season. Some short duration crop like vegetables can also be incorporated into
cropping system with irrigation. To make cropping pattern more remunerating
some of the following strategies may be adopted in Middle KolabMultipurpose
Project area.
i) Maximization of Kharif Crop Area
Basin water needs to be conserved and used judiciously. In rainy season paddy
should be grown only when water is not limiting. In water deficient areas crops
with low water requirement like pulses and oilseed should be grown. Cultivable
land should be covered with crops to the maximum extent possible even in rarified
area because crops can be grown without irrigation in rainy season which may not
be feasible in winter season.
ii) Promotion of Cash Crops in Kharif Season
Judicious use of Rabi water can be made by growing short duration cash crops like
vegetables in Kharif season. Long duration crops may suffer due to failure of
seasonal rains while short duration crops may escape with limited loss. Planting
time of short duration crops can also be adjusted according to onset of rains which
may not be possible for long duration of crops.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-8: Command Area 8-3
iii) Adoption of Important Technology
Modern package of practices should be adopted for cultivation of crops. It
envisages use of high yielding varieties, use of input like seed, fertilizers,
pesticides etc. and also non-monetary inputs like time of plantings intercultural,
harvesting etc. Emphasis should be laid on growing high value plantation crops
like tea, coffee etc. Extension services can play an important role for guidance and
providing necessary help to farmers.
iv) Efficient use of Conserved Moisture
Rain water must be conserved and should be put to proper use in the following
season. Planting time of Rabi crops may be advanced to make proper use of soil
moisture at germination stage. Growing crops with low water requirement in Rabi
season may be another approach in this direction. Water saving devices like
sprinkler and drip irrigation should be adopted wherever feasible to save water.
Significant amount of water can be saved by these techniques especially in widely
spaced crops. Allied enterprises like, flower cultivation, fishery, medicinal and
aromatic crops and poultry can be incorporated into the system to augment income
of the farmers.
v) Conjunctive use of Groundwater and Optimization of Cropping Pattern
The greatest potential for groundwater development rests in conjunctive use with
surface-supply to alleviate the problems associated with hydrological uncertainty.
Planning of Integrated development of Surface and Groundwater resources,with a
view to enhance the use of water resources optimally and to avoid problems such
as water loggings, soil salinity, which is now being increasingly realized in
irrigated command, is need of present day water resources development
requirement. In fact, National Water Policy enunciates that integrated and
coordinated development of surface water and ground water resources through
conjunctive use should be envisaged right from the project planning stage for such
projects.
The selection of an optimum cropping pattern is governed by a number of complex
factors viz., characteristics of soil, drainage requirements, general topography,
climatic conditions, size and type of farms, traditional crop practices, net return to
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-8: Command Area 8-4
the farmer and other factors that determine market demand and prices. For a given
project, the relative influence of these agro-climatic, agro-economic and
sociological conditions must be considered for arriving at the most suitable
cropping system i.e., crops and cropping pattern. The constraints of land and water
availability are of course to be taken into account. While projecting a cropping
pattern and irrigation intensity, other factors as relevant to optimal design of an
irrigation system, (minimizing the cost of irrigation facilities) are:
(a) Time Pattern of availability of Water
The cropping pattern should be such that the seasonal/short duration irrigation
requirements of the crop follow more or less, the time pattern of availability of
water from the sources (e.g. rivers/reservoirs, tanks, groundwater, etc).
(b) Reducing peak (or flattening of water demand)
The peak water demand can be minimized by synchronizing periods of peak crop
water requirements with the period of rainfall and/or low evaporative demand by
adjusting seasonal cropping intensities.
(c) Minimizing total irrigation requirement
Optimum use of seasonal rainfall and water stored in soil needs to be planned to
minimize total irrigation requirements. This necessitates selection of crops with
low seasonal irrigation requirements, and use of efficient methods of field
irrigation.
(d) Feasibility
Actual crops, cropping patterns and cropping intensities very often differ from the
designed cropping pattern (and cropping intensities). While projecting most
suitable optimal cropping pattern, one must also consider constraints that may arise
due to canal capacity system and the land or water availability, and build into the
system required flexibility.
Based on these considerations, the proposed cropping for the command area of
Middle Kolab Multipurpose Project canal system has been planned.
vi) Availability of Credit
Farmers need money for buying inputs, machinery etc. to grow crops with
improved technology. Farmers may be in a position to grow high-input high-
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-8: Command Area 8-5
output crops if their purchasing power improves. They may be able to grow crops
which may involve high risk. Credit at reasonable rates will go a long way in
improving financial conditions of the farmers in availing credit and improve their
standard of living.
8.3 AGRICULTURE
8.3.1 Irrigated and Rain fed Farm Practices
The rain fed crops are grown with the onset of monsoon intermittent dry spells
usually occur during the growing period. Farmers follow the repeated intercultural
operation to save their crops from moisture stress. Sometimes, heavy spells of rain
causes severe loss to crop yields. The surplus arrangements for runoff are adequate
in sloppy lands but the temporary water logging may occur in flat lands. The
application of fertilizers is below the recommendations in rain fed crops because of
uncertainty of production. However, there is not adequate supply of agriculture
input and a large no. of private and co-operative retail outlets are distributed all
over the area.
8.3.2 Farmers’ Attitude
In general farmers are willing to adopt new technologies. But their financial status
does not allow them to grow high input crops. Farmers are aware about high
yielding varieties and new technologies. If irrigation facilities are developed the
farmers will be willing to pay irrigation charges and grow more remunerative
crops. Paddy, which is main crop now, can be replaced by other crops like pulses
and oilseeds.
8.3.3 Extension Support
Extension support services should be made are available at Tehsil level. In this
project an extensive extension support will be required. Therefore, more extension
officers may be posted in the command area by reorganizing the available staff. In
this respect, Agriculture Department may reorganize the existing staff in the
interest of the project.
8.3.4 Strategy
It is proposed to make most effective use of water fromMiddle Kolab Multipurpose
Project for irrigation of standing crops and also to store excess water for future use
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-8: Command Area 8-6
in tanks in the command area. The water stored in tanks will be used when supply
of water is not adequate for meeting the requirement of standing crops, especially
in Rabi and Kharif seasons. It is also proposed to make effective use of soil
moisture preserved from rainfall by advancing the planting of Rabi crops in such a
way that the seeds of Rabi crops germinate before the soil moisture is lost through
soil evaporation. To meet the above objectives, the following strategies are
proposed for adoption:
a) To maximize Kharif crop area
An attempt will be made to utilize rain water in Kharif season. For this, there is a
need to conserve soil moisture and then use it in all the command areas. Proper
conservation and utilization of rain water will result in increase in the area of
Kharif crops. Here, the crops with low water requirement should be preferred over
paddy.
b) Promoting cash crops in Kharif season to maximize the use of available water
In Kharif season, the cultivation of vegetables will be given priority. In addition,
crops like groundnut, oilseeds, etc., which are highly responsive to irrigation
should be adopted. On the other hand, the traditional crops like paddy, maize, ragi
should be reduced in area owing to their high water requirement and / or low
productivity. Attempts should be made to advance the planting of these crops so
that crops make better use of rain water which is not feasible at germination stage.
If crops are well-established before the onset of monsoon, they can consume water
more efficiently.
c) Supplementary irrigation to paddy crop
There is considerable area under wetlands in the command area where a traditional
crop of paddy is grown. In these areas, paddy is a productive and low risk crop
which also provides necessary staple food to the people. Due to uneven rainfall, it
sometimes becomes essential to provide irrigation to paddy crop. Paddy is a well-
established crop of the area and farmers cannot replace it with other crops in the
near future. It is also desirable that farmers should be encouraged to grow
improved varieties/ hybrids of paddy crop along with intensive plant protection
measures and judicious use of inputs like fertilizers and water.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-8: Command Area 8-7
d) Emphasis on high value crops and plantation crops
High value crops like tobacco, oilseeds, groundnuts etc.with low water requirement
should be introduced in the command area. In addition, plantation crops, which
require little water after initial growth and establishment are to be given priority.
Plantation and other perennial crops have low water requirement and usually
require lifesaving irrigation in summer season, which can be provided by tanks or
ground water.
Fruit crops can also be promoted after considering their marketing facilities,
processing and local consumption. These crops survive on consumptive use of
ground water after establishment in initial years.
e) Advancement of planting of Kharif crops
Nursery for paddy transplanting should be raised 2-3 weeks early, through ground
water irrigation. Thus the nursery will be ready for transplanting in early July
immediately on the onset of monsoon. The crop thus transplanted early has been
proved to give higher yield with consumption of the same quantity of water as
compared to late planted crop.
Similarly, other Kharif crops like maize and ragi also perform better if the crops
have established themselves in the field before actual start of the rainy season.
f) Early planting of Rabi crops to make use of residual moisture
Advancement of Rabi sowing to September-October should be emphasized so that
seeds may germinate with residual moisture in the soil and the crop can be grown
with one or two irrigations in Rabi season. At initial germination stage, moisture is
required in the top layer of the soil which has to be provided by a pre-sowing
irrigation under late sown condition. Thus, one irrigation can be saved by early
sowing on residual soil moisture. If a crop germinates satisfactorily, the plants can
withstand adverse conditions at later stages of growth.
g) Efficient use of late rains, tank and ground water for Rabi season crops
Agro-climatic conditions in the project area can support the crops throughout the
year. In general, the yield potential of crops is higher in Rabi season as compared
to Kharif season. But the cultivation in Rabi crop season mainly depends on
irrigation from tanks or ground water plus winter rains and conserved moisture
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-8: Command Area 8-8
from rainy season. To make judicious use of water resources for Rabi crops, the
following strategy is proposed:
i) Early sowing to make best possible use of conserved residual soil moisture
ii) Growing crops having low water requirement like pulses: After
harvesting of Kharif crops, pulses like Bengal gram, blackgram and
greengram can be sown on residual moisture. It will make double cropping
feasible, thereby increasing the income of farmers. Pulses (legumes) not
only work as water savers but also improve soil fertility by fixing
atmospheric nitrogen in the soil though their roots. Attempts are therefore,
to be made to maximize area under pulses in Rabi season.
iii) Adoption of efficient methods of irrigation for better use of tanks and
ground water resources: There is considerable loss of water through
open flood method of irrigation. It is advised that more efficient methods
should be adopted to minimize wastage of irrigation water. Use of pipes in
place of open channels can save water loss through leaching. Also,
improvised methods can be adopted for irrigation of wide spaced and
plantation crops. In field crops, ridge and furrows, contour or rings method
of irrigation can be adopted depending upon the crop and field conditions.
iv) Judicious use of water resources through pressurized irrigation
systems: The availability of water from tanks or ground water is limited in
Rabi season. This limited quantity of water can be efficiently used to cover
maximum cropped area by adopting sprinkler method for narrowly spaced
crops and drip irrigation for widely spaced and plantation crops. Crops like
groundnut, vegetables, flowers etc. can be successfully irrigated by
sprinkler method, while crops like fruits and vegetables can be grown with
drip irrigation. Sprinkler and drip methods save significant amount of
irrigation water without adversely affecting productivity and quality of
produce.
v) Augmenting water storage capacity of tanks: It is, therefore, proposed
that water storage capacity should be increased by increasing the number of
tanks and / or increasing the capacity of existing tanks. Tanks not only
supply irrigation water in Rabi season, but also recharge soil moisture level
in the surrounding fields.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-8: Command Area 8-9
vi) Cultivation of high yield potential crops in Rabi season: In winter
season, remunerative crops like maize, vegetables and fruits should be
given priority over other crops.
vii) Allied enterprises: Where irrigation water is available, non-conventional
activities like flower cultivation, cultivation of medicinal and aromatic
plants like mentha, citronella, lemongrass etc., animal husbandry, fisheries,
poultry etc. can also be adopted to supplement the income of farmers.
8.3.5 Potential Problems
Input and credit support facilities are not adequate in project area. Market linkages
are also weak for the farm products. A large number of cooperative societies are
functioning in the area but their area of working has to be specifically defined.
There is also need for aggressive extension support and adaptive trials in command
area. New technologies like drip irrigation and sprinkler also need to be supported
by extension department. With proper planning and implementation potential
problems can be overcome.
8.4 SOCIO–DEMOGRAPHIC PROFILE OF COMMAND AREA
The entire command area lies in Malkangiri district.The socio-demographic
profiles of the command district are as follows:

CHAPTER – 9
POWER POTENTIAL STUDIES
9.1 GENERAL
Power Potential Studies of a hydroelectric scheme forms a primary step in the
planning of a hydroelectric project. It is carried out for assessment of the available
power potential of a river /basin based on a certain set of inflows and head conditions
available at the site in years of different degree of reliability, in different periods of an
year and the estimation of generating capacity (KW), which is needed to be provided
in power station in order to generate the assessed quantity of energy (kwh). Moreover,
the power potential assessment forms the basis for the planning of layout and design
of the scheme and estimation of cost and evaluation of the financial aspect of the
scheme. In general, it can be used for examination of various configurations,
simulation of integration of new facilities into existing networks, establishment of the
performance of the facilities under various operating policies, optimizations of the
design of hydraulic components and evaluation of energy and power benefits etc.
Apart from above roles for the case of new hydro facilities, it also plays a very
important role in establishing the optimal operation for existing hydro facilities. It
permits the identification of policies likely to be able to increase the profitability of
the existing projects. It can also be used to examine various approaches concerning
the operation of hydro developments like regroupment of several developments in a
river system, sequential simulation involving production and/or hydraulic
importations from one complex to another, joint operation of numerous complexes
acting together to meet a common production objective etc. In the planning of
hydropower developments and deciding its installed capacity, two inter-connection
viz, with the water resource development of the river basin and with the power system
are to be kept in view because hydro-electric project form an integral part of the
overall development of the water resources of the river basin.
In the present chapter, the Power Potential studies have been carried out for Middle
Kolab Multipurpose Project, in which a powerhouses is proposed on head race tunnel
from Kerajodi Dam. The Projected power supply position for 12th Plan indicates that
there would be shortage of peak power in Odisha. The Execution of this project would
help in reducing the gap between supply and demand of power.
Middle Kolab Multipurpose Project Feasibility Report
Chapter-9: Power Potential Studies 9-2
9.2 AVAILABLE DATA
Power potential studies have been carried out based on the following data:
a) Monthly Discharge Data of Middle Kolab River near proposed diversion barrage
and monthly discharge of Kerajodi Nallah for the period 1971-72 to 1997-98 (i.e.
27 years data) was made available and the same has been used as inflow for the
power potential assessment after taking into account the downstream
environmental flow requirement below proposed diversion barrage.
b) Revised area capacity curve after taking into consideration the sedimentation
effect as work out
c) FRL, MDDL were taken as per the topographic condition, submergence and other
criteria used for fixation of these levels. A brief descriptions for the methods
used for fixation of these levels are given in this chapter in ensuing paragraphs.
9.3 WATER AVAILABILITY
The Computed yield series at the Project Site (from its own catchment and water
diverted through diversion barrage) on the monthly flow basis for the period 1971-72
to 1997-98 (i.e. for 27 years data) has been worked out and analyzed in Chapter – 5 on
“Hydrology”. The availability of water for power generation is estimated considering
two different cases.
a) Case-I:
Considering full inflow at the project site (water diverted through diversion
barrage and yield from its own catchment) after releasing 20% as Environmental
Flow (when full contribution from Joura Nallah is available if present
contribution continues in future as well)
b) Case-II:
Considering 50% flow from diversion barrage and full yield from its own
catchment (when the weir proposed by CWC is commissioned on Joura Nallah to
check the spill of Indravati River through it)
9.4 FIXATION OF FRL AND MDDL
To start with minimum draw down level (MDDL) of the reservoir was adopted based
on (i) Consideration of silting during the life of the project (ii) Optimization of power
Middle Kolab Multipurpose Project Feasibility Report
Chapter-9: Power Potential Studies 9-3
benefits and (iii) safe limit of operating heads of the generating units taking into
consideration site specific constraints, if any.
To start with, full reservoir level (FRL) for the scheme is determined based on the
approximate assessment storage requirement considering inflow data and with the
help of mass curve of inflow series by varying FRL & MDDL.
In second step, FRL and MDDL were varied and for each alternative, assessments of
power benefits were made. The technical constraints in raising the dam height,
various others related aspects of submergence and rehabilitation etc. are kept in view.
The fall in the efficiency of generating unit at heads lower and higher than rated head
were also considered in computing energy benefits and variations in tailrace level
considered. The benefits in case of each alternative are computed considering
appropriate value of firm and secondary energy generation. The selection of optimum
FRL & MDDL is based on the consideration of maximization of benefits and benefits
to cost ratio being more than unity.
9.4.1 Fixation of Tailrace Water Level (TWL)
The minimum tail water level, which corresponds to discharge of one generating unit
at 100% load and the maximum TWL corresponds to all the units running at full
loads. In the present study to be on safer side, TWL has been taken as per site
condition.
9.5 HEAD LOSSES
Net head is computed by deducting the tailrace level from the upstream water level
and the losses in the water conductor system. The Losses in water conductor system
comprise of:
(a) Hydraulic losses up to forebay,
(b) Hydraulic losses in penstock
The total head loss in the water conductor system has been worked out taking into
consideration the head loss up to forebay consisting of a) entrance loss at diversion
intake and b) head loss due to friction in water conductor and the head loss in
Penstock consisting of a) friction loss, b) entrance loss, c) bend loss, d) loss in reducer
pipe and e) loss in manifold. The total head loss for the present scheme has been
worked out as 6% of gross head in present study.
Middle Kolab Multipurpose Project Feasibility Report
Chapter-9: Power Potential Studies 9-4
9.6 ASSESSMENT OF POWER POTENTIAL AND DEPENDABLE YEAR
As per Central Electricity Authority (CEA) guideline, the planning of HE Project is
carried out based on 90% dependability criteria where the 90% dependable year is
defined as a year that has the annual generation, which has the probability of being
equal to or exceeded 90 percent during the expected period of operation of the
scheme. Hence, if the total energy generation in the year for which hydrological data
is available (say N year) is arranged in descending order, the (N+1) x 0.9th year would
represent the 90 percent dependable year. On similar logic 50% dependable year
worked out. The 90% & 50% dependable year have been determined on the following
basis, where N is the number of years for which inflow data is available.
90% year - (N+1) x 0.9 = 28 x 0.9 = 25th Year
50% year - (N+1) x 0.5 = 28 x 0.5 = 14th Year
Based on the above, 1988-89 and 1986–87 are worked out to be 90% & 50%
dependable years respectively.
In the present study for determining 90% & 50% dependable year, annual energy
generation for all the 27 years (1971-72 to 1997-98) have been computed assuming
unlimited install capacity using the conventional method suggested by CEA for
computation of annual energy.
In the conventional approach, the annual energy for unlimited installed capacity was
worked out wherein the net operating head for turbines has been calculated from the
following formula.
= MDDL + 2/3(FRL – MDDL) - Average Tail Water Level - Head losses
The Results of year wise power potential and energy generation calculated using
conventional approach assuming FRL as RL 528m aMSL and MDDL as RL 482m
aMSL. Tail water level has been taken as RL 260m aMSL. The detailed calculations
are given in Annexure 9.1 (for Case-I) and Annexure-9.2 (for Case-II).
9.7 INSTALLED CAPACITY
In the present study installed capacity has been computed for both the cases, i.e.,
Case-I (With Full Jourah Nalla Contribution if present contribution continues in
future as well and 20% released downstream as environmental flow) and Case-II
Middle Kolab Multipurpose Project Feasibility Report
Chapter-9: Power Potential Studies 9-5
(With 50% Contribution of Jourah Nalla as compared to present contribution after
construction of proposed weir by CWC). Installed capacity is selected after carrying
out incremental analysis for the most attractive alternative and also considering load
factor. Benefits due to the project with different possible installed capacities are
evaluated to determine the optimum installed capacity. Energy generation and firm
power in 50% and 90% dependable year for FRL 528m has been computed for both
the cases.
For optimization of installed capacity, annual energy generation (KWh), incremental
energy generation d(KWh) and ratio of incremental energy to incremental installed
capacity d(KWh)/d(KW) have been computed for 90% and 50% dependable years for
installed capacity ranging from 280 MW to 340 MW and 190 MW to 212 MW for
Case-I and Case-II respectively. The results are indicated in Table-6 to 8 of
Annexure-9.1 and Annexure-9.2 for both the cases. For both the scenario, it would
be seen there from that d(KWh)/d(KW) has steep drop for increase in installed
capacity from 315 MW to 320 MW for Case-I and from 200 MW to 205 MW for
Case-II. Keeping these into consideration, the install capacity has been kept as 315
MW and 200MW for Case-I & Case-II respectively.
9.8 NUMBER, TYPE OF TURBINE AND RATING
Regarding number of units to be installed for the storage based scheme; there could be
wide variety of options. However, following three options viz. Very large unit and
Small Unit Size for generating units are considered here under
We studies hydrology thoroughly, and keeping in mind the overall project
components, overall costs, indigenously available top quality products, etc., and also
considered various options before taking final choice in the matter. It was finally
decided that three unit of 100MW each will be suitable for this purpose, because if
present trend of Joura nallah continues then all the three unit will be operational with
S. No. Number of Units
1 1 unit of 200 MW
2 2 units of 100 MW each
3 3 units of 100 MW each

Chapter-9: Power Potential Studies 9-6
5 to 10 % percent overloading. In case Joura nallah flow get reduced the two unit will
run full and remaining one unit will be used for peaking and/or standby.
Francis turbine is the appropriate choice in this case considering rated head of about
237.5 m and rated discharge of 94.2 cumecs. The following efficiencies pertaining to
Francis turbine driven generating unit have been considered for power potential
studies:
- Efficiency of Turbine - 93.5%
- Efficiency of Generator - 98.0%
- Combined efficiency of - 91.63%

10.5CONSTRUCTION EQUIPMENT PLANNING
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-10: Construction Programme 10-7
In order to attain faster progress while achieving consistent quality simultaneously,mechanical construction has been planned for almost all types of constructionactivities. Extra care has been taken up for equipment planning for excavation andother construction work to expedite the construction.
To ensure optimum utilization of equipment and its total requirement at a time,wherever possible, construction activities have been planned in such a manner thatequipment from one activity, on its completion can be shifted to the related nextactivity.
The existing access roads are neither adequate nor suitable for movement of men andmaterials at the project. These need to be repaired, remodeled and renovated in thepreconstruction stage and new roads need to be constructed prior to the start of mainwork. Arrangement to install construction power should be accorded due attention andpriority.
a) Scheduled Working Hours
Requirement of equipment is worked out based on equipment planning and thenumber of working days available. About 8 months i.e., October to May willform the working season in the barrage area. All the surface works are proposed tobe executed in two shifts except the barrage area, which is proposed to be executedin three-shift operations. The scheduled working hours considering 25 working daysper month accordingly works out as under:

On the basis of the above computation, in accordance with “Guidelines forDetailed Calculations for the Requirement of Each Category and Size of theProduction Equipment, August 2000 published by the Central Water Commission”following scheduled working hours have been considered in surface works.
Single shift work/day - 1200 hrs.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-10: Construction Programme 10-8
Two shift work/day - 2000 hrs. Three shift work/day - 2500 hrs.
The production capability would be affected during monsoon months especially forthe supplies/services and muck disposal, etc., suitable reduction in the progresshas been taken into account for the year as a whole. Two shifts working ofequipment is normally considered most economical in view of the high cost ofthree shift working on account of low availability of equipment and higher stand-byequipment requirement.
Thus, planning for all over ground works has been carried out based on two shiftsper day working. The work in the dam especially below the crest level will have tobe completed within the non-monsoon period only and as such planned for the 3shift working.
Provision of stand by equipment has been considered as follows:
Single shift working - 10%
Two shift working - 20% Three shift working - 30%

CHAPTER – 11RESRVOIR SIMULATION STUDIES
11.1 GENERAL
The Inflow series from 1971-72 to 1997-98 has been considered to carry out the
reservoir simulation studies on monthly basis for Middle Kolab Multipurpose Project.
The pattern of water availability on monthly basis reveals that the water availability in
the month of May also corresponds to lean flow and the effect of rains in increasing
the water availability starts from the month of June onwards. The hydrological year
for reservoir simulation studies, therefore, has been considered from the month of
June to May. The reservoir levels have been varied depending upon the quantum of
water in the reservoir. Tail water levels corresponding to the water discharges
through the canal have been determined. The friction loss in the water conductor
system has been also considered. The details of reservoir operation studies on
monthly basis are given in Annexure – 11.1
11.2 AVAILABLE DATA
Power potential studies have been carried out based on the following data:
a) Monthly Discharge Data for the period 1971-72 to 1997-98 (i.e. 27 years data)
b) Revised area capacity curve after taking into consideration the sedimentation
effect as work out in Chapter-5 (Hydrology)
c) Monthly Evaporation loss (in mm) data have been considered, which is
enumerated below:
Jun. Jul. Aug. Sept. Oct. Nov. Dec. Jan. Feb. Mar. Apr. May

d) FRL, MDDL were taken as per the topographic condition, submergence and other
criteria used for fixation of these levels. The tail water level and head loss were
taken as per the actual calculation for these parameters.
11.3 FIXATION OF FRL AND MDDL
To start with minimum draw down level (MDDL) of the reservoir was adopted based
on (i) Consideration of silting during the life of the project (ii) Optimization of power
benefits and (iii) safe limit of operating heads of the generating units taking into
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-11: Reservoir Simulation Studies 11-2
consideration site specific constraints, if any. To start with, full reservoir level (FRL)
for the scheme is determined based on the approximate assessment storage
requirement considering inflow data and with the help of mass curve of inflow series
by varying FRL & MDDL.
In second step, FRL and MDDL were varied and for each alternative, assessments of
power benefits were made. The technical constraints in raising the dam height,
various others related aspects of submergence and rehabilitation etc are kept in view.
The fall in the efficiency of generating unit at heads lower and higher than rated head
were also considered in computing energy benefits and variations in tailrace level
considered. The benefits in case of each alternative are computed considering
appropriate value of firm and secondary energy generation. The selection of optimum
FRL & MDDL is based on the consideration of maximization of benefits and benefits
to cost ratio being more than unity.
Reservoir simulations studies were carried out for entire hydrological data to work out
firm power and 90% dependable energy generation benefits corresponding to
alternative combination of FRLs and MDDL to select FRL form incremental cost and
benefits, submergence, stability and design considerations etc.
11.4 FIXATION OF TAILRACE WATER LEVEL (TWL)
The Computation of the Tail water-rating curve, which indicates the tail water level in
the reservoir at various discharges, was carried out considering gradually varied flow
condition d/s dam. The Analysis of gradually varied flow was accomplished by
computing the water surface profile using the energy equation, where the energy
equation was written in terms of water surface elevation (WS= y+z). It can be written
as

11.5 HEAD LOSSES
Net head is computed by deducting the tailrace level from the upstream water level
and the losses in the water conductor system. The Losses in water conductor system
comprise of:
(a) Hydraulic losses upto forebay
(b) Hydraulic losses in penstock
The total head loss in the water conductor system has been worked out taking into
consideration the head loss up to forebay consisting of a) entrance loss at diversion
intake and b) head loss due to friction in water conductor and the head loss in
Penstock consisting of a) friction loss, b) entrance loss, c) bend loss, d) loss in reducer
pipe and e) loss in manifold. The total head loss for the present scheme has been
worked out as 6% of Gross head.
11.6 RESERVOIR OPERATION
In General the Reservoir operation and energy generation is a function of power pool
volume (i.e., the volume of the reservoir allocated for power generation), the length of
the critical (dry) period, cumulative stream flow, the upstream storage (i.e. the
discharge into the reservoir), the average power head for generation and the schedule
needed to meet load requirements.. The constraint used for the optimizing of the
irrigation and power are enumerated below:

The head is calculated as a function of initial and final storages and the net height is
computed by deducting the tail water level and the frictional head loss in penstocks from
the total head.
The results are obtained sequentially using historic inflow data of 27 years. The carry
over storage of a year is taken care by giving the final storage of last month of previous
year as the initial storage to the next year first month. The nonlinear programming model
handles the nonlinearity in hydropower production representing the real world situation
in a better way and also incorporates the nonlinear over flow constraints effectively.
The details of the reservoir operation calculation are given in at the end of this chapter in
Annexure 11.1 (Sheet 1 through 27).

11.7 CONCLUSION
The results obtained from non-linear programming model for 27 years of historical
data were used to evaluate the performance of irrigation system in terms of the
percentage irrigation deficit. It can be seen from the tables of results given in
Annexure-11.1, that the irrigation deficit occurs mainly in the month of June – July,
whenever the monsoon in weak during this period for a year under consideration.
Simulation studies based on 27 years of data shows that, there are success in more
than 75% of the year (i.e. failure in less than 7 years of the magnitude of irrigation
deficit more than 5%). As such the proposed Middle Kolab scheme will be able to
provide reliable irrigation supplies as per CWC norms.

The relevant environmental impacts out of the entire gamut of issues outlined in the
Scoping Matrix shall be identified. For these impacts or aspects, environmental
baseline data shall be collected from secondary as well as primary data sources.
Baseline study: Before the start of the project, it is essential to ascertain the baseline
levels of appropriate environmental parameters, which could be significantly affected
by the implementation of the project. The planning of baseline survey shall emanate
from short-listing of impacts prepared during identification. The baseline study
involves both fieldwork and review of existing documents, which is necessary for
identification of data, which may already have been collected for other purposes.
Impact prediction: is essentially a process to forecast the future environmental
conditions of the project area that might be expected to occur as a result of the
construction and operation of the proposed project. An attempt shall be made to
forecast future environmental conditions quantitatively to the extent possible. But for
certain parameters which cannot be quantified, qualitative assessment shall be done so
that planners and decision makers are aware of their existence as well as their possible
implications.
Environmental Management Plan: The approach for formulation of an
Environmental Management Plan (EMP) is to maximize the positive environmental
impacts and minimize the negative ones. The steps taken shall consist of
modifications of plans, engineering designs, construction schedules and techniques, as
well as operational and management practices. After selection of suitable
Middle Kolab Multipurpose Project Detailed Project Report

environmental mitigation measures, cost required for implementation of various
management measures shall also be estimated, to have an idea of their cost-
effectiveness.
Environmental Monitoring Programme: A post-project environmental monitoring
programme shall be suggested to oversee the environmental safeguards, to ascertain
the agreement between prediction and reality and to suggest remedial measures not
foreseen during the planning stage but arising during operation and to generate data
for further use.
12.3 DESCRIPTION OF ENVIRONMENT
The baseline status on Environment has been described in the following sections.
12.3.1 PHYSIO-CHEMICAL ASPECTS
a. Meteorology
The Project area has the typical tropical monsoon climate with high summer
temperature and heavy rainfall between June and October. The mean maximum
temperature rises to about 38o C in April and May. The minimum temperature
falls to 12o C in December. The average rainfall is 1522 mm. The mean relative
humidity recorded in the morning and evenings are 51.72 and 26.6% respectively.
Mean daily evaporation is about 3 mm in the district. The wind velocity ranges
from 4-11 km/hr. The maximum relative humidity is 72% while the maximum
and minimum evaporation ranges from 1.2 mm to 7.9 mm.
b. Temperature
December and January are the coldest with mean daily maximum and minimum
temperatures being 24.5oC and 10.3oC. Both of these temperatures increase
thereafter till may which is hottest month with mean daily maximum and
minimum temperatures at 34.3oC and 21.4oC. On individual days in the month of
May and June before the onset of the monsoon, the temperature may shoot above
44oC. The highest recorded at Koraput was 46.6oC on 06 June 1967 and the
minimum 3.0o C on 27 Dec 1969.
c. Wind
Winds are generally light throughout the year except during the southwest
monsoon season, when winds are stronger.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-12: Environmental Aspects 12-6
d. Geology
The strata of Orissa state forms a part of the north eastern extension of the
Peninsular shield. Orissa state is by and large underlain by Precambrian rocks. A
little less than 25 percent of the total area of the state is constituted of the
Phanerozoic rocks, quaternary formations and the recent to sub-recent alluvium.
Particularly in Koraput district, the existence of remnants of Laterite and Bauxite
covered plantation surfaces (erosion plains) at different altitudes leaves no doubt
that the land was subjected to one of the most epeirogenic movements, probably
in the quaternary period.
It is proposed to include the group of Meta sediments and basic rock (Sukma
Group) occurring in the South-Western part of Orissa in Koraput district in the
iron ore group. However, the trends vary from north-south in the Sukma rocks
(Koraput) to east-western in the Sambalpur district. Orissa has been divided into
five major morphological regions, which are as under:
1) Orissa Coastal plain in the east.
2) The middle mountains.
3) The Central Plateau
4) The Western rolling uplands
5) The major flood plains
The Kolab/Sabari basin lies in Nabarangpur - Jeypore Plateau. The Plateau is
most eroded plateau forming the western slopes of Eastern Ghats with elevation
varying from 305-610 meters.
e. Soils
Taking into account the soil type, climate and topography the state has been
divided into ten agro climatic zones as shown in the table below. The soil quality
index of Orissa state (0.54) is very low as compared to the neighboring states.
The state has different types of soil types ranging from fertile alluvial deltaic soils
in coastal plains, mixed red and black soils in central table land, red and yellow
soils with low fertility in northern plateau and red, black and brown forest soils in
Eastern Ghats region.

The Koraput district follows under the northern Eastern Ghats agro climatic zone.
The north Eastern Ghats agro climatic zone comprises of brown forest soils,
sandy loam, loamy & clay, medium textured. The soil type is loamy but in higher
elevation the soil is rocky with small to big boulders. On the basis of aridity
index, the state can be divided into four zones:
Sr No Zone classification based upon aridity index Classification of district1 High moisture deficit zone(45 and above) North-western districts2 Moderately high moisture deficit zone(40 to 45) South coastal districts3 Medium moisture deficit zone(35 to 40) Central table-land districts4 Low moisture deficit zone(35 and less) North coastal districts
f. Water quality
Based on literature review, water quality of River Kolab does not indicate
presence of harmful ingredients in the water at intake site and water is suitable for
meeting irrigation or domestic water requirement. As a part of the EIA study,
water quality of River Kolab at the intake site shall be monitored. In addition,
groundwater quality in the command area too will be monitored at various
locations to assess the suitability of water for meeting domestic and irrigation
requirements.
g. Ambient air quality
Based on the review of secondary data, ambient air quality of the command area
can be considered to be good. This is attributed to absence of large scale
emissions from the air polluting industries. Vehicular density is quite low in the
area to cause any significant impact on the ambient air quality.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-12: Environmental Aspects 12-8
As a part of the EIA study, it is proposed to monitor ambient air quality at various
locations in the project area. The parameters to be monitored shall be PM2.5 and
PM10, Respirable Particulate Matter (RPM), Sulphurdioxide (SO2) and Nitrogen
Oxides (NOx).
h. Ambient noise levels
As part of EIA Study a detailed ambient noise monitoring shall be carried out at
various locations in the project area. It is proposed to monitor hourly equivalent
noise level during day time, subsequently day time equivalent noise levels will be
estimated and compared with permissible standards.
12.4 PREDICTION OF IMPACTS
12.4.1 Positive Impacts
The major anticipated positive impacts considered as a part of the study are listed as
below:
Higher yields
Industrialization and urbanization
Improvement in livestock
Reduction in soil erosion
Improvement in socio-economic condition
a. Higher yields
The project will provide sustained irrigation over an area of 24543 ha. This will
improve the irrigation intensity and correspondingly the yields would increase
resulting in increased agriculture production.
b. Industrialization and urbanization
The proposed project will lead to a significant improvement leap in the agricultural
production of the command area. This, subsequently, will increase the money flow in
the command areas. The increased agricultural production will automatically lead to
industrialization and demand for better infrastructural facilities. There will be an
increased migration in the command area as it will provide better economic avenues
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-12: Environmental Aspects 12-9
in comparison with the surrounding area. There will be an increase in small scale
agro-based industries.
The secondary benefit of industrialization and higher crop yields is to increase the
demand for improvement in infrastructural facilities. This will lead to improvements
in roads, communication, markets, storage yards, service yards, etc. as tertiary
benefits. The construction and operation of these facilities will also lead to an
improvement in the employment scenarios in the post-project phase.
c. Improvement in Livestock
The improvement in the irrigation in the command area will indirectly improve the
quality of livestock. The improvement in agriculture production would lead to
increased availability of fodder as a result of use of agriculture by products as fodder.
This increased availability of fodder will reduce the stresses on existing pastures. This
is a significant positive impact.
d. Reduction in soil erosion
After introduction of irrigation, there will be an increase is soil moisture, vegetal
cover, and improved land grading conditions which would help reducing soil erosion.
Generally it has been observed that with introduction of irrigation, the farm
management practices improve resulting in reduction of soil erosion from fauna.
e. Improvement in socio-economic conditions
In post-project phase, agricultural production will add to earnings in the pre-project
phase. Inflow of money will increase demands for services such as sewerage system,
communication, transportation, recreation, schools, hospitals, etc. The presumed
benefit of all these development is generation of additional employment. This array of
services can provide amenities hitherto lacking and stimulate changes in the tasks
performed by women in society and to the status of women within the society.
However, unless the aggregate supply of consumer goods and services available to the
workers and small farmers increases in proportion to the change in aggregate
increases, additional employment may only trigger a rise in price levels, leaving only
owners of land and capital on beneficiaries. These contingencies should be met with
careful planning, construction, operation and maintenance of infrastructure facilities.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-12: Environmental Aspects 12-10
12.4.2 Negative Impacts
Water Resources Projects, like all other development projects, contribute to many
desirable and undesirable environmental and social effects. A wide variety of subjects
are of significance in major water resources projects, encompassing physical sciences
such as hydrology, landuse, agricultural development; biological sciences such as
forests, wildlife, social sciences such as rehabilitation, human health and general
poultry alleviation. All these issues have a bearing on the overall environmental
quality, both directly and indirectly. In recent years much public attention has been
focused on the dependence of development activities on the careful planning and
management of natural resources for ensuring sustainable development. This section
deals with anticipated negative impacts likely to result due to proposed project. The
impacts are classified under the following categories:
impacts due to project location
impacts due to project design
impact due to project construction
impacts due to project operation
a. Impacts due to project location
The potential impacts due to project location are:
displacement of population due to project appurtenances
loss of lands due to siting of the project components
Displacement of population due to canal network in the command area
The proposed canal network in the command area will pass through several villages.
The endeavour will be to avoid acquisition of homestead. However, village including
private/panchayat/government land is likely to be as a result of canal alignment
through various villages. Since the acquisition involves only of a narrow strip of land,
there will not be any displacement of population involved due to proposed canal
network. However, adequate compensation needs to be given as per the norms of
National Policy for Resettlement & Rehabilitation (2003).
b. Impacts due to project design
The potential impacts due to project design are:
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-12: Environmental Aspects 12-11
disruption of hydrological balance
effect on water resources
Disruption of Hydrological balance
Sufficient water is available in the river between February to October. During the
months from November to January, to avoid disruption of hydrological balance, a
minimum of 20% of flow in River Kolab downstream of the proposed intake point
would be released.
Effect of Water Resources
The main objective of irrigation is to maintain the moisture content of the root zone
above a given level. This increases the soil moisture content. The higher soil moisture
content decreases the gradient of the downward flow near the surface and the
infiltration as well. Since, a balance has to be maintained, this process causes an
increase in surface runoff. On the other hand, infiltration through the surface is
smaller due to the decreased tension difference. The positive accretion is greater
because the storage capacity is filled by irrigation water and therefore almost the total
amount of infiltrating precipitation reaches the water table. The other consequence of
the continuous high moisture content near the surface is the decrease of negative
accretion. The tension on the surface of the thicker water film is small and therefore
part of the total potential directed upwards is also reduced. Generally, it becomes
smaller than the gravitational ground water only if the water potential is near the
surface. The excess recharge and the considerable decrease is vertical drainage
disturbs the natural balance of the ground water; hence irrigation results in a
continuous rise of the water table.
c. Impacts due to construction works
The impacts due to project construction are generally short term in nature.
Appropriate measures should be included in the work plan. The impacts included in
this category are:
soil erosion at construction sites
pollution by construction spoils
health risks
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-12: Environmental Aspects 12-12
Soil erosion at construction sites
Runoff from the unprotected excavated areas, quarry sites, can result in soil erosion.
However, in the proposed project a canal network is proposed to be constructed, the
construction sites will be linear in nature, level the effect of soil erosion will not be as
severe as it is normally for a site like dam, reservoir etc.
Pollution by construction spoils
The construction material will be required for various structures. Generally, such
materials are collected from nearby sites. Hence, a large quantity of earth work is
likely to be excavated. Normally construction waste is disposed in a haphazard
manner, without proper disposal. This can lead to water and land pollution.
Appropriate management measures shall be suggested as a part of the EIA study.
Health Risks
Generally, the workers during construction phase live in slum type conditions near the
construction sites. These sites do not have potable water or adequate sanitary
condition. This can lead to increased incidence of water-related diseases. Besides,
migration of labour from adjacent areas or labour already at site can be reservoir of
infection of various diseases. This can put the entire labour population of risk.
Proper care is also not given to drainage facilities in labour camps/colonies which can
lead to formation of small pool of stagnant water. This may serve as appropriate
breeding sites for mosquitoes and other vectors. It can also lead to increased incidence
of vector borne diseases like malaria.
d. Impacts due to Project Operation
The project will increase the irrigation intensity thus leading to higher yields which
will subsequently reduce soil nutrients. It will lead to reduction in fertility which will
be made up by the increased use of fertilizers. The possible environmental effects due
to the project operation can be summarised as follows:
Impacts on soil
Changes in water quality and risk of eutrophication
Increased incidence of water related diseases
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-12: Environmental Aspects 12-13
Impacts on soil
The introduction of irrigation increases the cropping intensity which could cause
change in soil fertility, soil structure and texture. Another noteworthy impact is the
reduction in permeability which along-with rise in ground water level could result in
water logging. The use of fertilizers is likely to increase in the post project phase.
Changes in water quality and risk of eutrophication
Water quality is an important concern of any water resources project. The increased
use of agro-chemicals is one of the major sources of water pollution. As mentioned
earlier, the continuous irrigation increases the runoff. The agro-chemicals are also
transported along-with runoff. The runoff ultimately gets stored in a stagnant water
body or small streams. In both the cases, the increased concentration of agro-
chemicals can cause eutrophication of water bodies. The project will also lead to
industrialization and urbanization. The effluent from these sources if disposed
without treatment can lead to water pollution.
Increased incidence of water related diseases
Major water related disease in the area is malaria. The malaria pathogens prevalent in
the area are P.vivax and P. falciperum. The common vectors are Anopheles
culicifacies and A. fluviafilis. The preferred environmental setting for vectors is fresh
water open to sunshine or moderate shade. The introduction of irrigation in command
area can increase small ponds, standing agricultural waters which are ideal breeding
sites for vectors. Experience suggests that if adequate measures are not taken, there
could be increased incidence of malaria in the project operation phase.
12.5 ENVIRONMENTAL MANAGEMENT PLAN
12.5.1 Environmental Measures During Construction Phase
Facilities in Labour Camps
It is proposed that it should be made mandatory for the contractor involved in the
construction activities to provide adequate facilities for water supply and sanitation in
the labour camps. It is recommended that the contractor provides living units of 30-40
m2 to each of the labour family involved in the construction activities. The unit shall
have proper ventilation.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-12: Environmental Aspects 12-14
Appropriate water supply sources shall be identified. Proper infrastructure for storage
and if required treatment e.g. disinfection or other units, shall also be provided. The
labour population migrating in the area during project construction phase shall live in
labour camps/colonies. One community toilet needs to be provided for 20 persons.
The sewage from the community toilets can be treated in a Sewage Treatment Plant
(STP) comprising of aerated lagoon and secondary settling tank.
Provision of community kitchen and Free Fuel
A community kitchen could be provided where workers have their meals. The fuel
used in such community kitchens could be LPG or diesel. The project authority in
association with the State Government should make necessary arrangements for
supply of kerosene/LPG. The fuel would be supplied at subsidised rates to the
local/contract labour for which provision should be kept in the cost estimate.
Solid waste management
The labour colonies will generate substantial amount of municipal wastes. Adequate
facilities for collection, conveyance and disposal of solid waste needs to be developed.
For solid waste collection, adequate number of masonry storage vats, each of 2 m3
capacity shall be constructed at appropriate locations in various labour camps. These
vats shall be emptied at regular intervals and the collected waste shall be transported
to landfill sites. Covered trucks to collect the solid waste from common collection
point and transfer it to the disposal site shall be put to service. A suitable landfill site
shall be identified and designed to contain municipal waste from various Project
Township, labour colonies, etc.
Restoration of construction sites
Normally the construction sites are left unreclaimed, with construction waste being
left without being properly disposed. In the proposed project, it is proposed to collect
construction waste from various construction sites, and disposed off at sites identified
in consultation with the district administration. Various construction sites would be
properly levelled. The levelling or reclamation of various construction sites, shall be
made mandatory for the contractor.
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-12: Environmental Aspects 12-15
12.5.2 MAINTENANCE OF WATER QUALITY
In the project operation phase, four or five project colonies are likely to be set up. It is
proposed to provide a sewage treatment plant comprising of aerated lagoon and
secondary setting tank at each colony for treatment of effluent before disposal.
12.5.3 HEALTH DELIVERY SYSTEM
The various measures for control of Public Health are listed as below:
Site selected for labour camps/colonies shall not be in the path of natural
drainage.
Adequate drainage system to dispose storm water drainage from the labour
colonies shall be provided.
Adequate vaccination and immunization facilities shall be provided for workers at
various construction sites.
Labour camps and resettlement sites shall be at least 2 to 3 km away from quarry
areas.
In the proposed project area, hospitals are already functional at Rayagada, Bastar,
Malkangiri, Nabarangpur, and Koraput. These hospitals have adequate facilities
in the terms of equipment, infrastructure and manpower. Hence, no specific
infrastructure development related to medical facilities is required. However,
first-aid posts manned by a doctor are recommended to be developed during
construction phase at various construction sites. The first-aid posts shall be
located so that they are close to major construction sites. These first-aid posts
shall have the following facilities:
First aid box with essential medicines including ORS packets
First aid appliances-splints and dressing materials
Stretcher, wheel chair, etc.
12.5.4 SUSTENANCE & ENHANCEMENT OF FISHERIES POTENTIAL
The commissioning of the proposed project will increase the water availability in the
command area. Most of the tanks are seasonal in nature i.e. water is not available
throughout the year for pisci-culture. At present, the shortage of water has an adverse
impact on their productivity. The increase in water availability due to the proposed
project will improve the productivity of existing tanks and ponds, but will also lead to
Middle Kolab Multipurpose Project Detailed Project Report
Chapter-12: Environmental Aspects 12-16
develop new tanks and ponds under pisciculture, coupled with increased productivity
from fish ponds will lead to significant increase in fish production.
12.5.5 CANAL BANK AND ROAD SIDE PLANTATION
The proposed project envisages construction of dam and canal network system .It is
proposed to develop plantation on both side of distributaries, which would improve
the overall aesthetics of the area.
12.5.6 INFRASTRUCTURE FOR AGRICULTURAL DEVELOPMENT
Financial and credit facilities
The credit agencies through their various rural development schemes can play a very
important role. An optimal combination of short term, intermediate term and long
term credits may be formulated to provide maximum benefits to the command area
population.
Marketing facilities and institutions
Improved marketing facilities and procedures contribute to waves of agricultural
development directly through providing greater use of a given level of production and
indirectly by fostering increased production. Inefficiencies in processing, storing and
transporting agricultural produce can cause actual loss of product
Efforts shall also be made to develop the transportation and storage facilities. The co-
operatives can play a very important role in the marketing of agricultural commodities
and supply of inputs to the farmers. The cooperatives through interaction with
government agencies, research institutes can popularise new farm inputs, marketing
facilities etc. These structures can be built as a part of various rural development
schemes of the state and central government.
12.5.7 TRAINING AND EXTENSION COURSES FOR FARMERS
The change from rainfed to irrigated cropping requires extension, training and
demonstration programmes for farmers. Considering these aspects it is proposed that
the project authorities need to provide adequate training to farmers. The training could
cover the following aspects:
Prevention of spread of water related diseases
Safe use of agro-chemicals

Chapter-12: Environmental Aspects 12-17
Environmental conservation programmes.
12.5.8 NOISE CONTROL MEASURES
The effect of high noise levels on the labour population involved in construction
activities is particularly harmful. To prevent these effects, it has been recommended
by international specialist organizations (OSHA) that the exposure period of affected
persons be limited. Alternatively, they should be provided with effective personal
protective measures such as ear muffs or ear plugs to be worn during periods of
exposure. The Noise specifications prescribed by OSHA are given in Table-3.

12.5.9 LIVESTOCK DEVELOPMENT
The following measures are recommended for improvement of livestock in the
command area:
Measures to improve availability and quality of feed
Improvement in standard of nutrition by increasing the availability and quality of
feed.
The proposed project would go a long way in improving the availability of fodder.
The improvement in marketing system to facilitate the movement of livestock and
livestock products, development of facilities to ensure easy availability to purchase
inputs like drugs, draught oxen, tools, etc., improvement in extension services by
regular organization of field demonstration and improvement in visual-aid facilities
would lead to overall development of livestock in the project area.

CHAPTER -15
ECONOMIC BENEFITS AND JUSTIFICATION
15.0 INTRODUCTION
It is natural for any investm ents, to search for a m easure of the benefits likely to be
derived from investments in the project. Thus, the main purpose of undertaking the
financial and econom ic analysis appraisal of a project is to assess its capacity to
maximize the efficient use of natural resources.
In the analytical system followed for this p roject, the “with” and “without” situations
are compared based on constant prices at current levels both for financial and
economic analysis.
The purpose of the economic analysis is to assess the real costs and benefits without
distortions due to taxes, subsidies, quotas or other factors influencing the value of the
products and services. The financial anal ysis is based not on economic values or
shadow prices but on the prices observed on the m arket. As such the purpose of
financial analysis is to assess the benefit of the project from the point of view of
farmer or individuals directly getting th e benefits, whereas the econ omic analysis
focus on the society as whole.
15.1 PROJECT EVALUATION METHODS
A wide variety of appraisal criteria (or evaluation methods) have been suggested in
literature to judge the w othehileness of the investment in the projects. T he important
and popular in use can be clas sified into two broad cate gories as (i) Discounting and
(ii) Non Discounting criteria.
The important discounting criteria are: Net Present Value, Benefit Cost Ratio a nd
internal rate of Return. The popular non-discounting crite ria are Payback period and
Accounting rate of return.
The Net present value o f a project is equal to the sum of the present value of all the
cash flows (inflows as well as outflows) associated with it.
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-2
The discounted benefit – cost ra tio is defined as ratio of present value of benefit and
present value of cost at social discount rate.
The Payback period is the length of time required to recover the initial cash outlay on
the project.
The accounting rate of return also referred to, as the average rate of return, is a
measure of profitability, which relates income to investm ents both m easure in
accounting terms. It is the ratio average income and initial investment.
The internal Rate of re turn (IRR) is defi ned as the rate o f interest, at which, the
discounted benefits and the discounted cost over the stipulated lif e of the project are
equal. The IRR based on fina ncial prices are denoted as FIRR and that based on
economical prices are denoted as EIRR.
15.2 CRITERIA FOR FINACIAL AND / OR ECONOMICAL VIABILITY
If a project is to be categorized as fi nancially and/ or ec onomically viable, the
following conditions must be satisfied.
1. The financial and econom ic viability of a project stipulates that the discounted
benefits, accruing as a result of the pr oject developments, should exceed the
discounted costs. This is generally done by e ither estimating net present value
(NPV) of the project i.e. ne t present value of benefit minus net present value of
cost or by determ ining the internal rate of return (IRR). The particular discount
rate, at which, the NPV of the project work s out to be zero or little higher than
zero, should not be low er than the opportunity cost of capital, i.e the appropriate
social discounts rate.
2. The BCR must be equal to or higher than unity with a discount rate as enumerated
in (i) above.
3. The IRR must be equal to or higher than the appropriate social discount rate, or
the opportunity cost of capital.
4. The Payback period is less than a certain specified payback period.
5. The accounting rate of return should exceed a certain cut off rate of return
6. The opportunity cost of capital in this analysis is 10 % which is same as assumed
by World Bank for developing countries.
From the theoretical point of view, the net present value method is clearly superior to
all other methods. For larger p rojects accounting rate of return and in more recen t
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-3
years, discounted cash flow m ethod are more commonly em ployed. For sm aller
projects the Pay back period m ethod appears to be popular. In U.S, Internal rate of
return, Net Present value, Accounting Rate of return and Payback period are the m ost
popular methods of project appraisal.
15.3 METHODOLOGY FOR WORKING OUT NET AGRICULTURAL INCOME
For the financial and econom ical appraisal of the irrigation schem e, a series of
budgets for various crops of the designe d cropping pattern have been prepared.
Financial and Economic crop budgets have been prepared for both the “Future
Without” (FWOP) and “Future W ith” (FWP) project situation. These crops budgets
include estimation of the gross value of the production and all direct production costs.
The objective of working out the crop budgets is to estimate the net return per ha of a
cropped area.
15.4 CROP BUDGET
Crop productivity is influenced by many endogenous and exogenous factors. It cannot
be precisely predicted due to aberrations brought about by the unpr edictable vagaries
of nature and unforeseen depredation by pest and disease. Further, it has neither fixed
input, output, coefficients of the type ev inced in the industria l product nor can the
aberrations be kept under check as in case of experiments under controlled laboratory
environments as in physics and chem istry, So add to these the fact that reliable
statistics on these are awfully lacking, it is necessary to make certain assum ptions
regarding, input-output rela tionships and productivity of crops under differe nt
situations.
Since there is a great deal of fluctuations in the market prices of various products and
Govt. regulate prices of certain inputs a nd outputs, the minimum support price where
ever available and the adm inistered prices of above inputs have been taken into
consideration for evaluating cost of input s and value of outputs for the entire post
project period, for those item s like bi-products, the prevailing market price of the bi-
product in the locality or its opportunity cost as a substitute of other item, have been
taken into consideration. The input prices of seeds, fertilizers (with sub sidy + taxes)
have been adopted from while the prices of other input like organic manure, wages of
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-4
animal labour have been obtained f rom the locality. The labour wage has been taken
as Rs.100/- per day which is m inimum statutory prescribed by the Govt. Changes in
prices over tim e due to over all changes in prices have been ignored as these will
equally affect the input prices and output prices. Besides th e fact that the installments
payment of loans and interest does not change over time due to changes in price level
adds credence to these assumptions.
Crop budgets were prepared for assessing th e crop benefits which can be expected
under “without” as well as under “with” Pr oject conditions. Cr op budgets were first
prepared in financial price term s and then converted to econom ic terms , for selected
crops as per the envisaged cropping pattern of the proj ect The Cro ps and th eir
cropping pattern under present a nd future both for “without” and “w ith” Project
situations are given in Table - 15.1.
15.4.1 Assumptions
Certain assumptions were made in preparing the Financial/Economic crop budgets, as
discussed below:
a. The cost of inputs includes expenditure on seeds, fertilizers, m anure, plant
protection chemicals, human labour, anim al power, m achine power and other
costs, including irrigation expenses, land revenue, deprec iation on tools and
implements, miscellaneous expenses and interest on operating cost (R efer Crop
Budget tables in Annexure 15.1 and 15.2).
b. The gross crop value includes the valu e of the m ain produce and by-products.
The crop yield for m ain product , By-produc t, and seed requirem ent and their
price as adopted in the present study are given in Table 15.2 (a) through 15.2 (c).
c. That the prices of input and output of various crops will rem ain constant. The
justification of this lies in that th e increase input and o utput prices will be
counterbalanced by inflation.
d. That the life of irrigation canal system is 100 years.
e. Under irrigated conditions in “with” Project si tuation, returns can reasonably be
expected to be commensurate with investments in production inputs.
f. Shift from the present use of local seeds under “without” Project situation, HYVs
(High Yielding Varieties) of seeds in the “with” Project future situation is
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-5
envisaged in cereals, pulses, and oil seeds, vegetable and other cash crops with
improvement in cultivation practices ,improved technology and management.
g. In the “with” projec t situation increase in the use of chem ical fertilizers is
envisaged in line with th e recommended practices and im proved technology, and
assuming optimal availability of other inputs.
h. Presently, agriculture is highly labour-i ntensive. There are, however, marked
peaks and slacks in dem and for labour in agriculture. Greater use of other
agricultural inputs will fu rther increase the dem and for labour. Since there is
already unemployment and underemployment of the agricultural labour force, any
increase in demand for labour due to the implementation of agriculture and water
resources development projects is not likely to pose any serious problem.
i. That the de velopment of irrigation infrastructure will be integra ted with othe r
agricultural activities to get full benefits of assured water supply
j. That necessary institutional support and services will be av ailable from various
departments concerned with supply of inputs a nd disposal of the outputs so that
the farmers adopt full package of practi ces and take full benefits from assured
water supply.
k. At present the use of anim al power is minimal, and depends upon the agricultural
practices being followed and the type of crops grown . With the advent of modern
technology, coupled w ith mechanized agriculture, the use of anim al power is
likely to continue to decline.
l. Presently the use of m achine power is at a low level and is going to increase in
future.
m. Depreciation has been considered only with respect to small tools and implements.
Certain items of storage, m arketing payments to artisans etc., were considered as
miscellaneous expenses.
n. That all extension activ ities will be g eared to educate the far mers for m aking
optimum utilization of irrigation potential created and that the full projected level
of output, income and employment will be attained by the 7th year of initiation of
the project.
o. That there will be h ardly any changes in th e exogenous factors (although not
realistic) influencing agricultural production.
p. That the n ecessary managerial s et up will be prov ided to m onitor the
implementation programme to attain the goals envisaged.
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-6
q. That the productivity of crops will b e as envisaged in Table 15.2(a) and 15.2(b)
with and without modernization of the project respectively.
15.4.2 Input Items for Crop Budget
The following input items were included in the crop budgets:
i) Value of seed
ii) Value of fertilizers
iii) Value of manure (FYM)
iv) Value of plant protection chemicals
v) Value of human labour (owned and hired)
vi) Value of animal power
vii) Value of machine power
viii) Value of water (only for “with” Project situation)
ix) Land revenue
x) Depreciation and Maintenance
xi) Transport cost
xii) Interest on working capital & miscellaneous expenditures
Costs of production per hectare of different crops are calculated by the Directorate of
Economics & Statistics, Govt. of India ( GOI), starting from the lowest cost ,
representing actual expenses in cash and kind incurred in production by the owner, or
operator, under the heading of operational costs, to the highest level, including all the
values of the imputed costs. The primary intention of these calculations is to estimate
the cost of production per quintal f or principal crops, so as to assist the Comm ission
of Cost and Prices (CAC&P ) in advising the G OI how to establish procurem ent and
support prices.
The practice of World Bank which is followe d in the preparation of Staff Appraisal
Reports (SARS) on irrigation projects, only the expenses in cash and kind actually
incurred by the farmers are generally considered. However items of operational costs,
like depreciation on m achinery and im plements, land revenue, m iscellaneous
expenditures, interest on working capital and expenditures like taxes etc. which are
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-7
generally not considered in the World Bank SARs, have been considered in preparing
the crop budgets for the present study.
The input application without project has been gleaned from the past experience based
on some survey and extrapolated for som e similar crops not covered in the survey.
The input application for the post project peri od have been obtained from the relevant
Farm Planning and Guide Book and agricultural practice manual which represents full
package of practices under assured water supply.
The current area under various crops repres enting the situation without project has
been extrapolated. The areas under various crops in future situation have been derived
from cropping pattern optim ization. The details irrigated and un-irrigated area under
“Present”, “Future without Project” and “Future with Project” are given in Table -
15.1.
15.4.3 Financial and Economic Crop Budgets
Both financial and econom ic crop budgets, for the “without” and the “with” project
situations were developed for the presen t study. A summ ary of the f inancial and
economic crop budget covering yield, gross retu rn, cost of production and net return
computed for different crops for present as well as future both for the “without” and
“with” situations can be seen in Crop Budget. Financial and Economic crop prices
used for preparing crop budgets both for “with out” and “with” proj ect situations are
given in Table-15.2(a) and 15.2(b). The Financial and Econom ic Crop Budgets are
presented in Annexure 15.1 and Annexure 15.2 respectively.
13.4.4 Incremental Agricultural Benefit Stream
In order to derive increm ental net financial economic benefit streams for agricultural
the methodology described in the earlier para s, has been used. On the basis of net
return per ha of cropped area the benefit for one ha of net cultivated area was worked
out under “Without” and “With “ project situations. Taking into accoun t the cropping
pattern the increm ental benefit from the project area has been estim ated. Since the
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-8
construction of dam and other works will be com pleted in the 3rd year itse lf, the
partial irrigation will be available from the 4th year onwards.
The farmer has already cultivating the la nd in command area and are w ell aware of
crop production. It has been assumed that 25% benefits form the crop production will
be achieved in the 4th year, 50% benefits in 5th year and full developm ent of crop
production except orange will be achieved in 7th year of the project.
The year wise increm ental income from the pro ject is presented in Table-15.4 and
15.6 for financial and economical analysis respectively. It has been assumed that once
the project reaches its full development stage in 7 th year the benefits will remain the
same for the project life.
15.5 PRICES
The entire analysis was done on constant pr ices. To estim ate the gross return per
hectare for agricultural produce, various kinds of prices, such market prices (retail and
wholesale), farm-gate prices and administered prices (procurement and support) could
be considered. For the purpose of present anal ysis, the farm gate (post-harvest) prices
were used. The far m gate prices were obtained from the Season and Crop report of
Directorate of Economics & Statistics, for the years 2008-09 as well as obtained from
field survey conducted in the project command areas. For the agricultural by-
products, the prices prevailing in the producing areas during 2008-09 have been taken
as the bas is, because, first, there is no Government procurement of agricu ltural by-
products, and second, the produced is assum ed to be consumed locally, obviating the
necessity for any adjustment of transport cost and loss in transit.
15.5.1 Financial and Economic Unit Prices
The financial prices of different inputs and outputs of different crops are based on the
observed prices in th e local m arkets and are generally those re portedly paid or
received by the farm ers. These fin ancial prices were ad justed where necessary to
reflect the opportunity cost to the society, thus expressi ng the econom ic prices of
inputs and outputs. For those item s are internally traded or substituting item s traded
on the international market, economic prices were based on the World Bank's
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-9
Commodity Price Projections given in the Global Econom ic Prospects, 2008. Crop
inputs or outputs not traded on the interna tional market were priced on the basis of
their financial prices. The derivation of various financial and economic prices used in
the analysis and their detailed calculations are presented in Tables 15.7 to 15.9.
15.5.2 Conversion Factors
For economic analys is purposes, th e costs and benefits of the Chinki Multipu rpose
Project have to be evaluated at world m arket prices so as to m easure correctly n et
economic benefits from this project. Thes e require certain adjustm ents, since, many
items are not trad ed on the world market and o thers are affected by tarif fs and trade
restrictions.
13.5.3 Standard Conversion Factor (SCF)
The benefits of the operation are evaluated at world market prices, i.e. they measure
what India would have to pay for imports or receive for exports. Most of the costs,
however, are for item s that are not traded on the world market. Tariffs and trad e
restrictions introduce a dist ortion in the price relati onship between traded goods
valued at world market prices and non-traded goods valued at local prices. Thus, the
costs are not directly co mparable with the benefits. In order to m ake them compared,
an SCF is applied to the price of non-traded goods and consumption.
Adjusting the financial prices to reflect economic values, involves determ ining an
appropriate premium attached to foreign exchange. The need to determine the foreign
exchange premium arises because in m any countries, as a result of national trade
policies (including tariffs on im ported goods and subsidies on export), a prem ium is
paid on traded goods, above what is paid for non- traded goods. The official
exchange rate is, therefore, multiplied by the foreign exchange premium which yields
a shadow foreign exchange rate. T he shadow exchange rate is then used to convert
the foreign exchange price of traded items into domestic currency.
The effect of using the s hadow exchange rate is to make traded items relatively more
expensive in term s of dom estic currency, by the am ount of foreign exchange
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-10
premium. This method is often used, and the relationship between the official and the
estimated exchange rates constitutes what is called the Standard Conversion Factor
(SCF).
In the absence of trade restrictions, the SCF can be approximately calculated using the
formula:
mx TMSXMXSCF
Where,
X = fob value of exports at the official exchange rate (OER);
M = cif value of imports at OER;
S = export subsidies;
Tm = import duties.
For India, SCF was assessed at 0.80 in 1980s, and subsequen tly at 0.85, to take
account of the real evolution of the econom y and the Indian Rupee. The rupee has
now become a convertible currency, at the cost of substantial devaluation and an
overseas trade which is subjec t to less and less taxes, restrictions o r subsidies. This
means that exchange rate of the Rupee, wh en compared with foreign currenc ies, is a
fairly close reflection of the shadow price of the foreign currencies, and therefore the
SCF can be taken as equal to one.
15.5.4 Prices of Agricultural Outputs
The economic prices for traded goods su ch as rice, wheat, cotton, groundnuts, and
sugarcane are based on their border prices at the official exchange rate (OER). The
domestic cost components (i.e. local transport and marketing charges) are adjusted by
the SCF of 0.80. The economic prices for non-traded foodgrains (sorghum, maize and
pulses are assumed to be non-traded) are derived by applying a foodgrain conversion
factor (FCF) to the f inancial price. The FCF can be es timated with th e following
formula:
FCF =[ (Q rice x PE rice) ÷ (Q wheat x PE wheat)]/[(Q rice x PF rice) + (Q wheat x
PF wheat)]
Where Q: Madhya Pradesh production
PE: Economic border price
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-11
PF: Financial price
15.5.5 Prices of Agricultural Inputs
Fertilizers, pesticides a nd insecticides are po tentially traded commodities; to m ake
allowance for taxes and subsidies and the total cost of trans port and m arketing, a
conversion factor of 0.95 has been applied to the financial price . The financial price
of bullocks and m iscellaneous charges have been multiplied by the SCF to express
them in economic terms. Analyses of farm labor supply and demand in various Indian
irrigation projects typically give an econom ic shadow wage rate for farm labor in the
range of 1/2 to 2/3 of the average financial wage rate. For the analysis of this project a
shadow wage rate of 65% of the market wage has been assumed.
Prices for traded items for which projections are not made, and for non-traded item s,
were calculated by adjusting the financial prices. Loca l costs, excluding those for
unskilled labour, were adjusted by applying the Standard Conversion Factor of 1. Cost
of unskilled labour was adjusted by both the S CF and by the Shadow Wage Factor
(SWF) of 0.50. The Econom ic Conversion Factor (ECF) for unskilled labour is thus
0.50. The market wage rate is considered to be a true reflection of the opportunity cost
of skilled labour. The economic price of skilled labour is valued at 100 percent of the
market or financial rate.
15.5.6 Construction Conversion Factor
The schemes would be constructed using a mixture of equipm ent, skilled and
unskilled labor. For the economic analysis, the CCF is estimated as follows:
(a) Traded Component — This com ponent includes capital—intensive works which
require imported materials. Since it is tr aded, the conversion factor is 1.00. It is
estimated that about 15% of the construction costs fall under this category.
(b) Non—Traded Component — This com ponent includes works that require skilled
labor and locally m anufactured materials.The SCF of 0.80 is used as the
conversion factor for these works. A bout 30% of the cons truction Costs are
included in this category.
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-12
(c) Unskilled Labor. A minim um wage is in force in Or issa. Since da ily workers
virtually never are paid above the m inimum wage, it is likely that this wage is
higher than the wage at which the worker s would be willing to work (i.e. their
supply price). Civil works construction is harder physical work than farming, and
experience from similar areas in India indicates that the laborers r equire a
premium of 25%—30% to shift from agriculture to construc tion work. By
comparison with agricultu ral wages in the State, it is estim ated that the
construction laborers’ supply price is about 15% to 20% below the m inimum
wage. This gives a shadow wage factor which is l0%—20% below the SCF, or
approximately equal to 0.65. It is estim ated that unskilled labor consti— tutes
about 55% of the construction cost.
Conversion Factor
Traded Items 1.00
Non—traded Items 0.80
Unskilled Labor 0.65
Construction Costs
(weighted average) 0.85
The resultant conversion factor for project construction cost s i.e. 85%. This is the
factor by w hich the financial cost of the work s expressed at the m arket price was
multiplied to obtain the shadow price for these works.
15.5.7 Land Acquisition and Resettlement Costs
Costs of the operation include the c ost of resettling families from villages submerged
by the reservoirs. The econom ic cost of re settlement is calculated by multiplying the
financial cost by the construction conversion factor (CCF). W here the cost of land
acquisition is concerned, the real cost to society is the opportunity cost, that is, the
production foregone by the subm ersion of the land in the reservoirs and the loss of
lands acquired for the construction of the distribution system. The per ha value of
production in the future “without project” situation was taken to represent this
opportunity cost and deducted from the benefit stream.
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-13
15.5.8 Conversion Factor for O & M Costs
Conversion factors for O & M involve two components which are (i) employment of
unskilled labour and (ii) m aterials and equipment with trad ed and non-traded
components. The Conversion Factors (CF) derived for O&M was also multiplied by
85%.
15.6 PROJECT BENEFITS
The first 5 years of the project have been reckoned as construction period. Hence the
cropping pattern in vogue remain the same as in the current period. Commencing with
the 7th year the farmer will start reaping the full benefit of assured water supply. The
extension activities should be geared from the very 1st year of construction to
motivate the farmers to switch on to the proposed cropping pattern and adopt m odern
technology so that they fo llow the recomm ended practices and take full benefit of
assured water supply. To attain this obj ective, CADA, Agriculture Department may
conduct one experiment in each panchayat in the farmers’ field on the benefits of ful l
package of practices where irrig ation is available and impart certain train ing to
farmers on water m anagement. Since these ar e part and parcel of the activities of
CADA works and Agriculture Departm ent, no separate budgetary provision need be
made in the project for this work. There s hould be a vigorous extension effort by the
district authorities to produce biofertili ser, Rhyzobium culture, com post manure,
agricultural machinery, pesticides, and distribute inputs li ke high yielding variety of
paddy, seeds, fertilizers etc. Further pr ogrammes have been m ade for im parting
certain on f arm training to the farm ers on different aspects of agriculture. It is
expected that all these efforts will boost up agricultural production and full package of
practices will be adopted with the commencement of the sixth year.
The quantum of various resources used in raising different crops during the kharif and
rabi season in the pre-project period have been adopted from the information available
for the project area.
15.6.1 Direct Benefits
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-14
i) Incremental Crop Production
The development of Chi nki Multipurpose Pr oject would a llow intensive farming of
32,540 ha of area under cultiv ation. Irrig ation will also allow full use of the land
which is not cultivated u nder current farming practices. The increm ental production
of crops f rom the developed land would be the benef it to the society. In additio n,
extra production will contribute to local food grains supplies and reduce regional and
national food grains deficits. The actual and incremental production of cereal, oilseed
and other crops due to project are summarized below:
ii) Increased Employment
The implementation of Irrigation Scheme will create employment opportunities in the
project area. The employment is associated with improved farming practices as well
as the construction of the irrigation schem e. With irrigation additional farm labour
would also be required as a result of higher cropping intensity through double
cropping providing employment opportunities to local people within and outside the
vicinity of the project area.
15.6.2 Indirect Benefits
This impact of project outcom e accuring fr om several ind irect and secondary no n-
farm benefit m ay originate from the produc tion aspect of the project as the value
added and em ployment opportunity gene rated by processing and new m arketing
activities, like transportation and storage services.
The impact is also felt in the increase in family working hours and increase in
employment opportunities of the wage earners, the latter get employment during slack
season and higher wages during peak load pe riod. Besides a great deal of indirect
employment opportunities in the processing storage, transportation and m arketing
fields will also be generated in the non- farm activities, emanating fro m the output
enhancement of the agricultural sector.
Other employment opportunity may emerge from the secondary or side effect of the
project in the form of providing services for recreation, health, power, education
facilities in the area.
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-15
Other social benefits are redistribution of income, eradication of poverty and increase
in standard of living in the rural areas.
This will also reduce the tendency of m igration of rural people to urban areas. The
inclusion of indirect and s econdary costs and benefits is very im portant element in
economic justification of the project, particularly in a state like Orissa where physical
resources are either idle or under utili zed and where one of the m ost important
purpose of the project is to absorb the unused and under used factors of production
and increase their efficiencies.
Most of th ese impact effects are of s ubjective nature and difficult to m easure
quantitatively. However, it is now tim e for the econom ist to derive input output,
coefficients for these indirect and seconda ry costs and benefits to gauge the full
outcome of the project. This will satisfy the advocate sugg esting realization of full
cost of the irrigation works from the farming community by levyi ng irrigation taxes.
In a nutshell, the indirect, secondary cost and benefit accruing from the project cannot
be overlooked for the purpose of m easuring the full im pact of the project and for
expressing a judgment on its social worthiness.
i) Poverty Eradication/Food security
Improved crop production through the comm issioning of the irrigation scheme
will increase farm income in the project area. Food supply will increase and there
will be cash income available for food or other purchases.
ii) Risk benefits
Project Districts Adm inistration vis–a-vis State Govt. risk s are con siderably
reduced through irrigation and the higher cropping intensities will protect the
authorities against shortfall in crop production. W ith the existing population
structure and its rapid growth in the project area, the long term benefits from
irrigation are even more important. Reliable water supplies along with improved
package of agricultural practices may encourage farmers to go for round the year
crop production to take advantage of market conditions.
iii) Transfer of Technology
Project Districts Agricultural Departments will be in a sound position to introduce
modern agricultural technology and farming practices to retain the fertility status
Middle Kolab Multipurpose Project Feasibility Report
Chapter-15: Economic Benefits & Justifications 15-16
of the soil with the installation of the irrigation scheme. This may also serve as a
demonstration to other farmers in the region.
iv) Health and Nutrition
Increased cash income resulting from increased crop production and employm ent
opportunities would result in higher per capita consumption of a greater variety of
food items. This in turn will im prove the nutrition levels of the people in the
project area.
v) Environmental Facility
The irrigation scheme will im prove the ov erall environmental and e cological
situations in the project area which in turn will reduce the health hazard.
15.7 MARKETING OUTLOOK
The marketing of increased ag riculture output resulting from modernization
programme will not pos e any serio us problem firstly, because the cro ps like r ice,
pulses, vegetables, oil seeds, proposed to be grown in the pos t project period are
traditional crops of the localities m eant for local consumption. Thus it h as got a vas t
unsatiated local market which can absorb the a dditional output with the increase in
employment and income of the farmers and non farm rural people secondly there are a
number of oil m ills in the loca lity to mop up the oils eeds crops. Thirdly, the
infrastructure like storage, transportation and other communication facilities are well
developed to convey the surplus product of these commodities and other perishable
commodities, like vegetables, from the producing area to the urban markets.
Supply and distribution of input will not al so pose any problem as there are a num ber
of retail outlets for supply and distribution of all agricultural input s in the ru ral area.
The minimum support prices of agricu lture commodities are anno unced by the
Agricultural price Comm ission well ahead of the comm encement of the cropping
season. These support prices based on the survey, through cost accounting method, on
the cost of production of various m ajor crops in various parts of the country. The
prices of some of the important input lik e fertilizer, seeds etc. are reg ulated by the
Government. It is expected that th ese regulatory activities will prevail th oughout the
post project period, notwithstanding the liberalization policy of the Govt.

14.8 PROJECT COST
15.8.1 Project Financial Cost
The total financial cost of the project is Rs. 14470.2 Million. The 70% expenditure
will be incurred during the first three year s and the rem aining 30% amount shall be
paid to the contractor in fourth and fift h year. Operation and Maintenance (O & M)
cost at the rate of 1109 per ha has been assum ed from 4th year onward. The year wise
project cost and O&M have also been given in the Table-15.3 for financial analysis.
15.8.2 Project Economical Cost
The economic cost includes capital invest ment and O & M cost of the proposed
irrigation scheme. The economic cost has been obtained after adjusting the financial
cost for opportunity cost, taxes and standa rd conversion factor. The sam e parameters
have been applied for estim ating economic cost, as has been applied foe estim ating
the economic benefits. Details f or estimating economic prices and standard
conversion factor are given in the earlier para and results are given in Table-15.5.
15.9 FINANCIAL AND ECONOMIC ANALYSIS – RESULT
15.9.1 Financial Analysis
Project analysis has been carried out to cover as total period of 100 ye ars from the
year of the star t of the construc tion of the project. The year wise n et incremental
return in the “with” project situation over “without” pr oject situation has been
computed as under and given under 15.5.
Net Incremental Return = Net return in “with” Project situation minus Net return in
the “without” Project situation.
The flow of costs and benefits has been di scounted at base di scount rates (10%) to
formulate discounted cash flow stream s. The Table-15.3 gives the year wise project
investment costs, O&M costs, and total i nvestment costs. The Table-15.4 gives the
financial IRR calculation with project net incremental return and net cash flow stream

calculated at the base discount rate. It also gives the FIRR i.e. discount rate, at which
with the stream of cash flow, will give ze ro Net Project V alue or Net Project Value
tends to zero at the end year of the eval uated period. The Financial Internal Rate of
Return (FIRR) for this project is found to be 21.09% percent and NPV value at 10%
discount rate works out to be Rs. 17116 million.
15.9.2 Economic Analysis
Derivation of economic prices for the purpose of econom ic analysis are discussed in
earlier para. The net econom ic benefit of the project area is given in Table 15.6. The
Economic Internal Rate of Return (EIRR) produced by the 100 year net cash flow is
22.50% percent and NPV value at 10% disc ount rate works out to be Rs. 16614
million and is given in Table 15.6.
