A dam is defined as a barrier that divides water, and dams generally serve the primary purpose of retaining water. India has the largest number of water dams in the world after the United States of America and China. It has two of the top ten dams in the world: the Tehri Dam 261m and Keshaw Dam 253m. Efforts have been combined to preserve water resources, and provide what would ensure life on the surface of the earth through the construction of dam projects and making maximum use of them. Dams aim to store water for irrigation and drinking, to face drought crises in some years, and to reduce the risk of floods. Water dams play a major role in sustainable development in the agriculture and energy sectors, given that water is the basis on which agriculture and energy are based. The development of agriculture and energy inevitably leads to the recovery of the economy as a whole.
