Presentation Team

Overview of the presentation

K.A.S.Mani-Hydrogeologist J.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

HGraph.exe


• 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
