Capital Territory of Delhi. On an average, about 6000 forecasts are being issued during flood
      season every year by the Central Water Commission. Normally, these forecasts are issued 12 to
      48 hours in advance, depending upon the river terrain, the locations of the flood forecasting sites
      and base stations. The current flood forecasting methodology is being modernised using rainfall-
      runoff mathematical model like Mike-11 and area inundation modelling.
            The Commission is carrying out surveys and investigations for preparation of Detailed
      Project Reports (DPRs) in the NE region, Sikkim, Uttarakhand, Bihar and J&K on the request of
      the respective states for development of water resource potential for irrigation, hydropower and
      other uses. The projects which are presently under investigation are Kalez Khola HE Project
      (Sikkim), Rukni and Sonai Irrigation Project (Assam),Katakhal Irrigation Project(Assam),Kali
      Khola HE Project (Sikkim), Tarum Chu HE Project(Sikkim), Suntley HE Project(Sikkim),
      Twalang HE Project(Mizoram),Ujh Multipurpose Project, 280MW , Kathua(J&K), Bariniun HE
      Project (J&K).
      Morphological Studies
            The study of river morphology and implementation of suitable river training work as
      appropriate have become imperative as large areas of the country are affected by floods every
      year causing severe damage to life and property in spite of existing flood control measures taken
      both by central and state governments. Problems are aggregating mainly due to large quantity of
      silt/ sediment being carried and deposited in its downstream reaches. The special behaviour of
      the river needs to be thoroughly understood for evolving effective strategies to overcome the
      problem posed by it. Morphological study of three rivers namely, Ghaghra, Sutluj and Gandak
      has been completed. Further, morphological studies of 15 rivers namely Ganga, Sharda, Rapti,
      Kosi, Bagmati, Yamuna, Bramhaputra, Subansiri, Pagladiya, Krishna, Tungbhadra, Mahananda,
      Mahanadi, Hooghly, and Tapti is under progress.
      Design Consultancy
            Central Water Commission is actively associated with design of majority of the mega water
      resources projects in India and neighbouring countries viz., Nepal, Bhutan, Afghanistan,
      Myanmar, Sri Lanka and African countries by way of design consultancy or in the technical
      appraisal of the projects. Four design units are functioning to cater to specific requirements and
      to attend to special design related problems of different regions.
      Dam Rehabilitation & Improvement Project
            Dam Rehabilitation and Improvement Project (DRIP) is the World Bank assisted project at
      an estimated cost of ₹ 2,100 crore with the provision of rehabilitation of about 223 large dams in
      the seven participating states (namely Jharkhand, Karnataka, Kerala, Madhya Pradesh, Odisha,
      Tamil Nadu and Uttarakhand) along with institutional strengthening component for participating
      states and Central Water Commission.
      National Register of Large Dams
            As per the latest information compiled under the National Register of Large Dams (NRLD)
      maintained by CWC, there are 5701 large dams in the country. Out of this, 5254 large dams have
      been completed and 447 others are under construction. The NRLD is available on CWC website.
