Geo-hydrological Detail of River Narmada
The Narmada basin, hemmed between Vindya and Satpura ranges, extends over an area of98,796 km2 (38,145.3 sq mi) and lies between east longitudes 72 degrees 32' to 81 degrees 45'and north latitudes 21 degrees 20' to 23 degrees 45' lying on the northern extremity of theDeccan Plateau. The basin covers large areas in the states of Madhya Pradesh (81%), Gujarat(12%) and a comparatively smaller area (4%) in Maharashtra, (2%) in Chattisgarh and (1%) inAndhra Pradesh. In the river course of 1,312 km (815.2 mi) explained above, there are 41tributaries, out of which 22 are from the Satpuda range and the rest on the right bank are fromthe Vindhya range.[4] Dhupgarh (1,350m), near Pachmarhi is the highest point of the Narmadabasin.
The basin has five well defined physiographic regions. They are:(1) The upper hilly areas coveringthe districts of Shahdol, Mandla, Durg, Balaghat and Seoni, (2) The upper plains covering thedistricts of Jabalpur, Narsinghpur, Sagar, Damoh, Chhindwara, Hosangabad, Betul, Raisen andSehore, (3) The middle plains covering the districts of Khandwa, part of Khargone, Dewas, Indoreand Dhar, (4) The lower hilly areas covering part of the west Nimar, Jhabua, Dhulia, Narmadaand parts of Vadodara, and (5) the lower plains covering mainly the districts of Narmada,Bharuch, and parts of Vadodara. The hill regions are well forested. The upper, middle and lowerplains are broad and fertile areas, well suited for cultivation. The Narmada basin mainly consistsof black soils. The coastal plains in Gujarat are composed of alluvial clays with a layer of blacksoils on the surface.[9]
Lower Narmada Zone
Brief description: The location of Lower Narmada and Tapi subzone- 3(b) has been showan mapof India, as also delineation of 26 subzone into which the country has been devided for theppurpose of the hydrological studies. The subzone 3(b) is bounded by Chambal basin on theNorth, Run of Kutch and Arabian sea on the west, Upper Godavari and konkan on the south andupper Narmada and Tapi basin on the east. Important cities and towns within the subzone aresurat, vadodra, Jalgion, Khandwa and Bhusaval. The total area of subzone is about 77700 Sq. km.

DETAILS ON MINING / EXCAVATION ACTIVITIES Method of Mining
Mining of the minerals is done by scraping/dredging the mineral from active channel or
Floodplain or terrace.
Mining of the minerals is done by scraping/dragging the mineral in ½ meter strip. Then
the mining is restricted up to 2 m depth only.
Average depth of water at lease area is: Max: 10.0 m to 12.0 m Min: 04.0 m to 06.0 m.
The Average thickness of sand deposit at lease area is: 4.0 meter.
Type of mining is: Semi Mechanized (By scraping/dredging the mineral)
Equipments used are: Sand Dredger with pump & Truck.
Minimum setback distance from river bank is: 40 meter.
Minimum distance of stockpiles / vehicle loading place from the river bank is: 30 meter
Man power requirement: 10 people
Average No. of working days in a year: 210 days(Approx.)
Time of working hours in a day is: 8:00 am to 6:00 pm
In-stream extraction of sand from below the water level of a stream generally causes
more changes to the natural hydrologic processes than limiting extraction to a reference
point above the water level.
Extracting sand from a large river or stream will generally create less impact than
extracting the same amount of material from a smaller river or stream.
The potential impacts of sand extraction are as under…
a) Bed degradation and consequent effects on channel and bank stability
b) Increased sediment loads, decreased water clarity;
c) Changes in channel morphology and disturbance of ecologically important roughness
elements in the river bed;
d) Ecological effects on bird nesting, fish migration, etc.
e) Modification of the riparian zone ﴾wet land) including bank erosion;
[6]
f) Discharges from equipment and refueling;
g) Reduction in groundwater elevations;
h) Impacts on structures and access;
i) Impacts on coastal processes.
Impact on Air EnvironmentSources: Fugitive emission occurs due to movement of vehicles on roads. The quantity of
emissions depends on various aspects like climatic conditions, moisture in the soil, speedof the vehicle, frequency of the vehicles etc.
The key air emissions from the project are dusting combustion of fuel from thetransportation vehicles as well as material handling. The main air pollutants will beparticulate matter, nitrogen dioxide and sulpher dioxide
The mined sand is transported to the sites through 10/16 MT Trucks. The loading operation is manual/ mechanical using material handling equipment.Impacts: Respiratory system can be damaged of workers/people living in nearby area due to dust
generation. Frequent movement of heavily loaded vehicles across the river banks not only imposes
land stability problems but also pollutes the river water through oil/gasoline spillage.
Impact of Noise Transportation vehicles used for the transportation of mineral are a source of Noise
pollution at the Mine site.
Impact on Land Use Pattern and Change of River Course The physical composition and stability of substrates are altered as a result of in-stream
mining and most of these physical effects may exacerbate sediment entrainment in thechannel. Excess sediment is considered the greatest pollutant in water and constitutesone of the major environmental factors in the degradation of stream fisheries
If the mining is not carried out in a uniform manner then it will disturb the riverflow/course in the terms of its uniformity. Unplanned mining activities can lead to riverchannel shifting as well as degradation of land, causing loss of properties anddegradation of landscape. Some physical impacts are as under…
1) The undercutting and collapse of river banks,2) The loss of adjacent land and/or structures,3) Upstream erosion as a result of an increase in channel slope and changes in flow
velocity4) Downstream erosion due to increased carrying capacity of the stream,
downstream changes in patterns of Deposition and changes in channel bed andhabitat type.
5) Riverbed lowering6) Changing the course of the riverbed
[7]
Impact on Water Environment Mining may cause lowering of riverbed level as well as river water level resulting in
lowering of groundwater table due to excessive extraction and draining out ofgroundwater from the adjacent areas. This may cause shortage of water for thevegetation and human settlements in the vicinity.
Indiscriminate sand mining from the rivers can lead to destruction of riparian vegetationwhich acts as resting and nesting grounds of many migratory birds.
The in stream fish wealth of the rivers may be decreased year after year consequent tounabated sand mining and subsequent habitat loss.
Extensive use of high power suction pumps for extraction of sand from the river hasaggravated the salt water intrusion problems especially in the lowland river reaches
Effects directly related to extraction and to changes in geomorphology include increasedsedimentation, turbidity, and bank full widths, higher stream temperatures, reduceddissolved oxygen, decreased wetted periods in riparian wetlands, and degraded riparianhabitat.
Impact on Topography and Drainage Pattern Unplanned mining activities and stocking of unwanted material near the river bank can
affect the natural topography of the River bed. Mining pits are responsible for riverchannel shifting as well as degradation of land and landscape.
Impact on Soil No major impact on soil of the study area is envisaged due to mining activities as the
minerals are replenish able and get replenished every year.
Impacts on Biological Environment Excessive sediment deposition for replenishment/ refilling of the pits affect turbidity,
prevent the penetration of the light required for photosynthesis of micro and macroflora which in turn reduces food availability for aquatic fauna. Increase in river gradientmay cause excessive erosion causing adverse effect on the in stream habitats.
Riparian flora and fauna suffer seriously from riverbank slumping, channel incision,lowering of water table etc., as a result of the direct removal of vegetation along theriver banks, bank undercutting and channel incision.
ENVIRONMENT MANAGEMENT PLAN AND MITIGATION MEASURES
Air Quality Management There will be emission from combustion of fuels from the transportation vehicles
and material handling. Besides this, to control the emissions further regular preventive maintenance of
equipments will be carried out on contractual basis. It shall be ensured that all transportation vehicles should carry a valid PUC
certificate.
[8]
Plantation will be carried out on approach roads & nearby vicinity of River bank. Regular water sprinkling on road will be carried out to avoid dustiness due to
vehicular transportation. Speed of the vehicles is maintained within the prescribed limits. Trucks are not be over loaded and should be maintained to the body level. Condition of all trucks will be well maintained Old age trucks will not be utilized;
Noise Management No other equipments except the Transportation vehicles and Excavator (as and when
required) for loading will be allowed. Noise generated by these equipments shall beintermittent and does not cause any impact.
All vehicles which create high noise will be avoided. Plantation will be carried out on approach roads & nearby vicinity of River bank. Proper maintenance of vehicles would be ensured. Mining activity will be restricted to day time only.
Management for Land Use Pattern Including Change of River Course The sediments will accumulate / replenish every year during rainy season. The minerals will be collected in a uniform way so that the river flow/course shall not
get disturbed. Scrapping/dredging of minerals shall be started from the centre towards the bank
periphery in ½ meter slice so that the river course does not get affected and a barrierof atleast 3 m will be left at both bank side for safety of banks.
Unused material including mineral or spillage (if any) will not be stocked on thebanks side as it will hinder the flow of river in monsoon season.
Suitable mitigation measures will be adopted to avoid water logging.
Water Quality Management No waste water will be generated from the mining activity of minerals as the project
only involves scraping of Sand from River bed. Mining will not intersect the Water level. Mining will be done well above the riverbed water table therefore impact on water
regime is not anticipated.
Solid Waste Management No solid waste will be generated from the said mining operations. Unused material including mineral or spillage (if any) will not be stocked on the
banks side in river bed as it will hinder the flow of river in monsoon season.
Socio Economic Environment The deployed laborers will be from nearby villages.
[9]
Occupational Health & Safety Dust masks will be provided to the workers, working in the dust prone zones. Study will be conducted to identify, occupational health hazards if any. Workers will be informed and trained about occupational health hazards if
identified. Any workers health related problem will be properly addressed. Adequate PPEs are provide to the workers during mining activity such as dust mask,
ear plug, life jacket, safety shoes, etc.
Greenbelt Development and Plantation Programme As the lease area falls in river bed, plantation & green belt development is not
possible within the lease area. Unit has proposed to carry out plantation in the vicinity of river banks, along the
approach roads, around Govt. buildings, schools. The Local species will be planted asper the CPCB guidelines.
Plan for tree plantation and budgetary outlay for the same: Total tree plantation area will be about 00-20-00 ha.

Production & Manufacturing Process
Sequence of operation with detail method of working are as below:
I. Mounting of Dredging machine on boat: All dredging machines are fixed on boat. Dredging
machine consist of motor which generate desired pressure for suction of slurry, suction pump
which are lowered in riverbed and outlet pump which throughout slurry to bank of river. The boat
fixed with mechanical dredgers is sailed in to lease area of river for the process operation.
II. Dredging of sand from Riverbed: All dredging machines are fixed on boat. The dredge drag
head is lowered on the river bottom to act like a vacuum cleaner. The dredge drag head is
connected to the boat by adjustable suction pipes or pressure pipe having foot valve attached to it
that excavate water with sand. Mechanical dredger trails its suction pipe when working, and water
jet is forced to the river bed with high pressure to make slurry of water and sand. After the slurry
is pumped through suction pipe and transported to the some distance from bank of river through
pipeline.
III. Screening: At some distance from bank of river (25 m), one broad pit (25ft x 20ft) is prepared in
which screen (6ftx 4ft) is placed. The mixture is thrown on screen through pipe so that larger
particles are separated from fine sand which is having potential application in construction and
industries. The course sand which has no potential use is dumped in wet condition in to artificial
pits so that it does not there is no any erosion if such materials by wind.
IV. Dewatering: The water which is pumped is send back to river through channel from screen and
storage area.
V. Stockpiling: Fine Screened sand particles are stored in spaced prepared.
VI. Transportation: Sand is transported from stored area to specific site for use through plastic
covered truck or tractor.
