Overview of the presentation

K.A.S.Mani-HydrogeologistJ.G. Grijsen-Team Leader


• Hydrology Project (HP) is a World Bank funded project with technical assistance from the Government of The Netherlands

• Implementation cost: US $122 million

• Technical Consultancy: US $15 million

• HP aims at the establishment of a Hydrological Information System (HIS) spread over nine states covering 1.7 m sq. kms.

Hydrology Project-India


Efficient water resources management calls for hydrological data which is:

• reliable

• authentic

• validated

• easily accessible

• regularly updated

Need for HIS


What is HIS

HIS includes the different activities related to

• data collection • processing • storage• dissemination

of meteorological,hydrological & geo-hydrological components of the hydrologic cycle


HIS - What does it do

• HIS enables regular update of the different components of the hydrologic cycle at the national, state and regional level

• Makes available the organised data as information to the Hydrological Data User Group (HDUG) which includes policy formulators, planners, developers and the user community.

• HIS provides critical input for major policy formulation, enhancing development options, improving technical solutions and sustainability of water resources.


• Collect reliable and spatially intensive data on SW/GW quantity and quality

• Standardise procedures for various activities across all SW/GW agencies

• Establish dedicated hydrological data processing software

• Organise data in well-defined databases

• Provide analytical and GIS tools for detailed interpretation

• Transform data as useful information for user friendly internet based dissemination

• Sustain the HIS through institutional strengthening & human resources development

Objectives of HIS


HIS - Developmental process • Emerging technologies in the field of software

development, data base management, internet , communications, GIS & GPS are being used in the development of HIS

• At the heart of HIS is its monitoring network

• Monitoring networks have been integrated between the agencies

• Contamination and pollution of groundwater prioritised for systematic monitoring, analysis and interpretation

• Human Resource Development and Institutional Development essential for sustaining the system

Groundwater Level monitoring

• Authentic ground water level collection using dedicated Piezometers

• Piezometers tap a single selected aquifer

• Piezometer facilitates collection of

uncontaminated water samples

• Digital Water Level Recorders for continuous monitoring at specified frequencies


Piezometer nests• Water level and water quality in multiaquifer

system monitored through piezometer nests

• Piezometers constructed to varying depths tapping different aquifers

• Individual aquifers isolated through proper sealing

• Water level monitoring of different zones for understanding the regional aquifer system

• Water quality sampling of different aquifers for identifying the source of contaminants


High frequency water level monitoring


• Monitoring network:

- baseline- trend - surveillance

• Use of high precision equipments & portable field kits for analysis

• Groundwater sampling using dedicated sampling pumps

• Analysis for chemical, bacteriological, trace elements, heavy metals, pesticides

• Water quality data interpreted using analytical software, GIS tools

HIS Sustainability• Extensive training programme

– Network design– Observation procedures– Data entry & processing – GIS and database management systems– WQ sampling and analysis– Procurement / installation / testing of equipments– Training and communication skills– Standardised training modules– Concept of ToTs (Training of Trainers)

• Deployment of dedicated staff• Provision of fund for annual O & M • Updation of technology


Gains from HIS

• Integrated Monitoring network• Dedicated software• Data centres and inter-agency data exchange• Standard procedures for data collection, analysis

and storage• Trained staff, training modules• Reference manuals for HIS operation• Computerised historical data• Transition from “technology shy” to “technology

friendly” environment• Improved data dissemination• Other institutional gains

– Water Quality Assessment Authority (WQAA)– Introduce concept of IWRM


Replicability of HIS• HIS as an integrated process for

managing the water resources system is relevant to countries facing floods, droughts and water quality issues

• HIS as implemented in India can be replicated elsewhere with local customisation

• Experiences gained in India would help in avoiding the teething troubles and reduce the implementation time
