Dams of India have been built across many perennial rivers since the independence of India. These dams in India are a part of several multi-purpose projects to serve a variety of needs. In a multi-purpose project‚ a river forms a unit and a river valley is developed‚ by exploiting all the resources of the river. Basically‚ dams are built to harness the river water so that it can be utilised according to the needs. A multipurpose project is launched often for storing water for irrigation purposes
