Dams in India and Their Importance

Dams are the structures which are created to hold back  the flowing water of rivers. And store the water for future uses. Which would have been wasted in the raining season and this water is used during the summer season when there is no rain. It  plays an important  role in water conservation. Dams have various uses and are important for humans as well as for nature.

Uses of Dams

  1. Stored water in the dam can be used for domestic, industry and irrigation purposes.
  2. Hydroelectric power production is one of the most important uses of the dam. Which helps in  the generation of renewable energy.
  3. They help in flood control.
  4. It attracts tourists for boating and fishing which can be an income source for the government and local residents.

Type of Dams in India

  • Rock-Filled Dams: Rock-fill dams are embankments of compacted free-draining granular earth with an impervious zone. The earth utilized often contains a high percentage of large particles, hence the term “rock-fill”. Example : Tehri Dam
  • Concrete Gravity Dam is also known as “Gravity Arch Dam,” and is a freshwater-retaining concrete structure that has a wider footing (base) than the top-section. The purpose of a Concrete Gravity Dam is to maintain a low center of gravity, in order to avoid collapsing in the event of an abutment seal failure. Example  Bhakra Nangal Dam
  • Composite Dam : Composite dams are a combination of concrete and embankment dams. Construction materials of composite dams are the same used for concrete and embankment dams. Example : Hirakud Dam
  • Masonry dams are dams made out of masonry – mainly stone and brick, sometimes joined with mortar. They are either the gravity or the arch-gravity type. Example: Nagarjuna Sagar Dam
  • Gravity Dam: Dams constructed from concrete or stone masonry are Gravity dams. They are designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. These are designed in such a way that each section of the dam is stable and independent of other sections. Example : Sardar Sarovar Dam
