    River Basin Management

    The River Basin Management Scheme comprises of two main components namely:-

    1. Brahmaputra Board (Continued from previous plans)
    2. Investigation of Water Resource Development Scheme (Continued from previous plans)
      1. CWC component
      2. NWDA component

    1. Brahmaputra Board (Continued from previous plans):

    The Brahmaputra Board has been setup by an Act of Parliament, called the Brahmaputra Board Act, 1980 and it started functioning since 11th January, 1982 for planning and integrated implementation ofmeasures for control of floods and bank erosion in Brahmaputra and Barak Valley and for mattersconnected therewith. The states of Arunachal Pradesh, Assam, Meghalaya, parts of the states ofManipur, Mizoram, Nagaland, Tripura Sikkim and a part of West Bengal falling within the BrahmaputraBasin. It is carrying out following major works-

    1. Survey, Investigation & preparation of Master Plan;
    2. Preparation of DPR of Multipurpose Projects;
    3. Drainage Development Schemes;
    4. Anti-erosion works & Flood control works including Protection of Majuli Island from flood and erosion of the river Brahmaputra.
    5. a. Restoration of Dibang and Lohit Rivers to their original courses at Dhola-Hatighuli (Avulsion of Brahmaputra at Dholla-Hatighuli).
      b. Bank protection work at Bhogdebri area on the Right Bank of River Mansai in Cooch Behar District, West Bengal.
      c. Protection work at Mirem Village, Miglung Village &Remi Village” in East Siang District of Arunachal Pradesh .
      d. Protection Work at Oyan and Sile Village” in East Siang District, Arunachal Pradesh

    6. . Innovavtive/new measures initiated by the Brahmaputra Board:
    7. a.Scientific Dissemination and Improvement of Water Management practices of local tribes and indigenous people of NE Region;
      b.Bio-Engineering Measure for Flood and Erosion Management;
      c.Spring shed Management.

    2. Investigation of Water Resource Development Scheme (Continued from previous plans)

    1. CWC Component
      Investigation of Water Resource Development Scheme (IWRDS) – For establishing techno-economic viability, the first and basic requirement for a project is to locate a suitable site to establish its techno-economic viability. Then, DPR is prepared after detailed survey and investigations and studies on hydrological, irrigation planning, environment aspects, cropping pattern, crop water requirement etc.

    The river basins have been identified to fulfill the objectives of the proposal which are given below:

    1. Providing hydropower and increasing irrigation potential, especially in North- Eastern States.
    2. The new hydroelectric and irrigations projects will provide hydropower and irrigation benefits to the States, especially for North Eastern Region including Sikkim as well as Jammu & Kashmir.
    3. Special studies as proposed will explore the power and irrigation potential on the rivers in India.

    The DPR of 04 projects were successfully completed and submitted to the concerned State Governments and DEM was successfully generated to locate suitable sites for Irrigation on Adhwara group of Rivers in Sitamarhi District, Bihar during EFC period FY 2017-20 extended up to FY 2020-21. If taken up for implementation, the total expected benefits of these projects in terms of additional Hydropower potential and irrigation potential (CCA) would be 295 MW and 32000 ha respectively.

    NOTE: The EFC Memorandum which was earlier for FY 2017-20, has now been extended up to FY 2020-21.

    ii) NWDA Component

    As per National Perspective Plan (NPP) for Water Resources Development in 1980 nvisaging inter basin transfer of water from surplus to deficit basins, National Water Development Agency (NWDA) was set up under the MoWR in 1982 for carrying out various technical studies to establish the feasibility of the proposals of NPP. Based on the pre-requisite studies e.g. water balances for various sub-basins and diversion points in the country, storage / reservoir studies, toposheet& prefeasibility studies of link canal, NWDA identified
    30 links (14 Himalayan and 16 Peninsular) for preparing reports (FRs). NWDA completed the PFRs of all the 30 links and circulated to party States. The Feasibility Reports of 24 link projects (14 under Peninsular Component and 10 under Himalayan Component) were also completed. The DPRs of Ken- Betwa, Par-Tapi-Narmada, Damanganga-Pinjal, Godavari (Inchampalli barrage)-Cauvery (Grand Anicut){comprising of three links viz., Godavari-Krishna, Krishna-Pennar and Pennar-Cauvery}, Cauvery-Vaigai-Gundar link projects were also completed and circulated among party States.

    All the statutory clearances viz. Environmental, Wildlife, Stage-I forest clearance, investment clearance for Phase-I components of Ken-Betwa link project were accorded except CEC clearance of Hon’ble Supreme Court and Stage-II forest clearance which are in progress. Most of the clearances for Phase-II components have also been accorded by the concerned Ministries/Departments. A draft Cabinet Note for funding of the Ken-Betwa link project with 90(C):10(S) funding pattern was also circulated among various Ministries/Departments. The tripartite MoA for implementation of the Ken-Betwa link project was signed by Hon’ble Chief Ministers of UP, MP and Hon’ble Minister for Jal Shakti on 22.03.2021 in the august presence of Hon’ble Prime Minister of India. The approval of PIB was also obtained for funding of the project. Thereafter, subsequent to the approval of Union Government in December, 2021, the link project is presently under implementation.
    The studies related to remaining links are in various stages. The implementation of projects would create an additional irrigation potential of approximately 35 million hectare and generate about 34000 Mega Watts (MW) hydropower, apart from the incidental benefits of flood moderation, navigation, drinking and industrial water supply, fisheries, salinity and pollution control etc.

    In addition to the above, out of the 49 intra-State link proposals received from 10 States, NWDA completed the PFRs of 39 link projects and sent to the concerned States. Based on the request of concerned States, the DPRs of 6 link proposals were completed and sent to the concerned States.


    Out of the Rs.276.75 Crores allotted as outlay in the EFC during the period 2017-18 to 2019-20, NWDA incurred an expenditure of Rs.227.55 Crores. During the year 2020-21, out of the RE of 74.54 Crores, NWDA incurred an expenditure of Rs.68.79 Crores.The Outlay,Recurring,Non recurring Expenditures of NWDA for the past four years are furnished below:
