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