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

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
