Hydrology Project-India • 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.

Need for HIS Efficient water resources management calls for hydrological data which is: • reliable • authentic • validated • easily accessible • regularly updated

What is 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.

Objectives of HIS • 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

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

HP- Infrastructure profile 25 Participating Agencies Initiated in Sept 1995 and to be completed by March 2003 Significant numbers 7900 dedicated piezometers 7000 920 1800 150 80 1500 1600 580 31 390 9000 digital water level recorders river gauging stations rainfall stations full climatic stations water quality laboratories computer systems with dedicated software offices and site buildings vehicles data storage centres data entry and processing centres staff trained in different subjects

Meteorological network • 1800 rainfall stations • 150 full climatic stations

River gauging stations • 265 new stations • 650 stations upgraded • Current meters for velocity measurement • Digital Water Level Recorders for water level measurement • ADCPs for select gauging sites

Groundwater network • Integrated network made up of – 7500 piezometers – over 20, 000 open wells – 7000 DWLR’s • Network of different agencies integrated • Network optimised for better spatial & vertical coverage

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

Dedicated water quality network • 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 - Inter Agency Data Exchange • Regular exchange of data between the different agencies for validations • Generic data exchange standards for data mobility

Data Storage Centre • 31 Data Storage Centres (DSC) • One stop shop for data dissemination • Meta Data Catalogue on the web site and CD • Data on SW/GW (quantity and quality) • Current and historical, raw & interpreted

HIS- Deliverables Processed Data Maps Year Books Event reports Customised reports

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 To. Ts (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
