The National Water Development Agency was set up in 1982 to study the feasibility of the
      links under peninsular component of national perspective plan. The NWDA is fully funded by
      Government of India. Its functions were subsequently modified from time to time and the present
      functions include: (a) to carry out detailed survey and investigations of possible reservoir sites
      and inter-connecting links in order to establish feasibility of the proposal of peninsular river
      development and Himalayan river development components forming part of the National
      Perspective for Water Resources Development; (b) to carry out detailed studies about the
      quantum of water in various peninsular river systems and Himalayan river systems which can be
      transferred to other basins/states after meeting the reasonable needs of the basin/states in the
      foreseeable future; (c) to undertake/construct/repair/renovate/rehabilitate/ implement the projects
      either on its own or through an appointed agency/ organization/PSU or company and the projects
      forming part of interlinking of rivers, for completion of projects falling under PMKSY of which
      projects under Accelerated Irrigation Benefits Programme are also included and similar other
      projects.

      things as it may consider necessary, incidental or conducive to the attainment of the objectives
      for which the Institute has been established. To fulfil these objectives, the Institute has
      established state-of-art laboratory facilities in nuclear applications in hydrology, water quality,
      soil water, remote sensing and GIS applications, snow and glacier, numerical groundwater
      modelling and hydrological instrumentation.
           The Institute acts as a centre of excellence for transfer of technology, human resources
      development and institutional development in specialized areas of hydrology, and conducts user
      defined, demand-driven research through collaboration with relevant national and international
      organizations.
