» 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

» 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 FACED CHALLENGES FACED CONTD...CONTD...

» 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.

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.

» 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.

» 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.

» 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.

» 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.

» 3 Real Time Water Quality Monitoring System (RTWQMS) have been installed by CWC.

» DSS has been developed by NIH.

» Purpose Driven Studies were undertaken.

» 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 HIS SUSTAINABILITY OF HIS

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 HIS SUSTAINABILITY OF HIS CONTD..CONTD..

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

» 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.

» 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.

» 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.

» 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.

» 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.

» 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.

» 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.

» 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

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.
