Introduction to Hydrology Project-HP Need for HIS What is HIS Objectives of HIS Participating agencies in the programme Implementation methodology New technology introduced Benefits from HIS Scope for replication in other geographical areas Presentation Team 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

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

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 Dedicated water quality network

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 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
