Precipitation during monsoon :3000 BCM
Water availability :1869 BCM
Utilisable water availability :1123 BCM
Surface water-690 BCM
Ground water-433 BCM

6. » Food grain production to be doubled by 2050.
˃ Necessitate increased water demand for irrigation.
» Water demand for other sectors also on rise.
» Water availability for irrigation to go down.
» Challenge is to produce more food grain as
well as meet increased demand of other
sectors with limited water availability.
» Increasing urbanization is posing another
challenge to the water demands
CHALLENGES FACEDCHALLENGES FACED
7. » There are increase incidents of flooding attributed to
intense rainfall/ cloud burst and GLOF (glacial lake
outburst flood)
» There is progressive deterioration of water quality in
surface water bodies
» Increased demand for maintaining ecological flow in
the rivers.
» Increasing issues of salinity ingress in coastal area,
siltation of river and reservoir sedimentation
CHALLENGES FACEDCHALLENGES FACED CONTD...CONTD...
8. » Need to conserve monsoon flows & use water
efficiently for sustainable management.
» Need to prepare for perceived adverse impact of
climate change.
» CRISES leads to CONFLICT.
» These water related issues calls for better water
management.
» A scientifically managed Hydrological Information
System can provide the basic input to achieve this
objective as the challenges posed a multifaceted.

9. Hydrological information in India is
primarily provided by various agencies of
the Central and State Government.
HIS is the process of capturing reliable data
on the quantity and quality of hydro-
meteorological, hydrological and hydro-
geological systems on space and time.
It promotes the use of computerized
databases for planning, design and
management of water resources systems.
10. » In the HIS, procedures of observation,
processing and dissemination of water
resources data were standardized.
» It aimed at expansion of Hydrological and
Meteorological data collection network in 5
Central Agencies and 9 State Agencies.
» 380 data centers and 31 data storage centers
were established by IA’s of Centre and States.
11. » At Central Level National Surface Water Data Centre
(NSWDC) was established in CWC for storage of Hydro-
meteorological Data as Central Depository.
» Data Entry Software (SWDES), Software for Primary &
Secondary validation & processing (HYMOS) and Data
Storage and Dissemination software (WISDOM) were
developed.
» IA’s got the exposure to the system and developed
particular level of expertise in these software.
» Institutional strengthening through capacity building
was promoted.
12. » With the advent of newer technologies especially
robust internet system in remote locations, cloud
based computing facilities and modern Mobile
devices, it become imperative to introduce this new
concept and consolidate the gains made during HP-I.
» Development of web based software eSWIS
combining functionalities of all the three software
developed in HP-I i.e. SWDES, HYMOS & WISDOM
has been taken up under HP-II.
13. » To standardize Hydrological Design Practices in the form
of Design Aids for uniform use, all over the country,
using State of the Art Technology to the extent possible,
Hydrological Design Aids (HDA-SW), a tool for
Assessment of Water Resources Potential
Availability/Yield Assessment (HDA-Y), Estimation of
Design Flood (HDA-F) and Estimation of Sediment rate
(HDA-S) are under development.
14. » 3 Real Time Water
Quality Monitoring
System (RTWQMS)
have been installed by
CWC.
» DSS has been developed by NIH.
» Purpose Driven Studies were undertaken.
15. » The spread is limited to 13 States and 8 Central
Agencies only. The benefits to reach throughout
Country covering all river basin and States.
» Building of effective co-ordination mechanism
amongst different IA’s.
» Making available all data at a Central Location.
» Standardization of specification of latest equipment.
» Sustainability of the system/assets
developed/created.
» Training of staff/officers for O&M of the system
created.
SUSTAINABILITY OF HISSUSTAINABILITY OF HIS
16. To evolve mechanism for updating of data at
regular interval.
Integration of Ground Water Information
system.
Integration of Water Utilisation data,
agriculture data by State Governments as
these databases will be useful for
reassessment of water resources availability
study, Basin Planning etc.
Bringing IMD, CPCB, Agriculture Ministry on
India-WRIS platform. Only then complete data
on water resources will be available.
SUSTAINABILITY OF HISSUSTAINABILITY OF HIS CONTD..CONTD..
17. Prime role of HIS beyond Hydrology Project
will be two folds:
» Integration of tools developed in HP-I and
HP-II in design, planning and operation
practices throughout the country.
» Generating technological inputs for future
ramping up of data management operation
qualitatively and quantitatively.
PRIME ROLE OF HIS
BEYOND HYDROLOGY PROJECT
18. » Supporting the IA’s/States in maintenance of HIS
in lieu of sharing of Data with central depository.
» Need to integrate HIS developed by IA’s/States
with Centre.
Need to standardize the data collection methods,
equipments required and communication system
for HIS so that ramping up operations are smooth.
Need to create Hydro-meteorological instrument
Data Bank/Guidelines and empanelment of
Firms/Supplier to help the IA’s for easy
procurement and maintaining the uniformity in
HIS.
19. » Spreading of HIS in the entire country.
» Institutional Strengthening & Capacity Building
required for sustainability of HIS developed
during HP such as implementation of HDA,
eSWIS.
CWC/Central Government to play a crucial and
essential role in management and
coordination of above activities.
20. » Responsibility to manage the various Control
Boards such as Cauvery Management Board,
Krishna Dispute Implementation Board, Ganga
Management Board etc. in view of rising Inter-state
water Disputes for which CWC/Central
Government is being mandated.
» Role of neutral DSS through CWC/Associated
Organisations in providing real time inflow forecast
for reservoir operation to individual units being
operated by independent agencies in Cascade
development of hydropower in the country which
is gaining importance now a days.
21. » Operation and management issues of
reservoirs, canals etc. of various Inter-state
rivers require more number of sites and their
data on real time basis.
» Expansion of H.O & Met network throughout
the country covering all river basin upto
Tributary/Sub-Tributary level. (800 new sites in 12th
Five Year plan).
» Modernization, integration and real time
collection & transmission of data.
22. » Developing Design Aids for Hydraulics
Structures and integration in design/planning
practice.
» Extension of Development of Regional Models.
» Integration and expansion of various RTDAS
and coupled DSS.
» Installation of more no. of RTWQMS at
major/important surface water bodies.
» Development of Flood Inundation
modeling/Generation of DEM.
23. » Development of Mobile based applications for
eSWIS.
» Flood Risk Zoning- River Front Development
» Bringing all Water Resource Information
under one umbrella under India-WRIS which
has been developed by CWC in collaboration
with NRSC.
» Creation of National Water Informatics
Centre.
25. » India-WRIS will provide a comprehensive, credible and
contextual view of India’s water resources data along
with allied natural resources data and information to
all stakeholders in water resource sector.
26. » It will allow users to Search, Access, Visualize,
Understand, Analyze, Look into context and
Study spatial patterns.
» ‘Single Window’ solution of all water resources
and related data in a standardized GIS format
in national framework for:
• Water resource assessment and monitoring,
• Water resource planning and development,
• Integrated water resources management
(IWRM) & provide foundation for advanced
modeling purposes
27. Integration of PMP Atlas being developed by
CWC
Integration of Hydrological Tools (e-SWIS, e-
GEMS, HDA) being Developed under HP-II
Crowd sourcing (Involving of Public) for
collecting data especially in respect of
smaller water bodies, water polluting
locations etc.
