Dams In India: How many Dams in India?

India is a land of 5,202 dams. A dam is a barrier that stops the flow of water and results in the creation of a reservoir. The use to build dams is because they are used to produce electricity by using water. There are approximately 4,300 dams that are fully constructed and the rest are under construction. Today, in this article we will be discussing all the important details of dams present in India.

Dams in India

There are various dams in India which are used for many purposes. At present there are around 5,202 dams in India, and we will be discussing all the important and major dams in India and the types of dams.

Uses of Dams:

Dams are useful in the following ways:

  1. They provide adequate water for domestic and city use.
  2. Provides water supply for irrigation.
  3. Generates Hydroelectric Power production
  4. Helps to control the flow of the river during the flood.
  5. Dams Reservoirs are used for fishing and boating purposes, thus providing livelihood to many.

Types of Dams

There are several types of dams built in India. The different types of Dams are:

  1. Gravity Dam: These types of Dams are constructed from concrete or stone. The main purpose of these types of dams is they are built 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.
  2. Arch Dam: These dams are designed so that the hydrostatic pressure (force of the water against it) presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments.
  3. Arch-gravity Dam: These dams include the characteristics of both arch dam and gravity dam. This dam curves upstream in a narrowing curve that directs most of the water pressure against the canyon rock walls.
  4. Embankment Dams: It is a large artificial dam is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil, sand, clay, or rock. 
  5. Rock-filled Dams: Rock-fill dams are embankments of compacted free-draining granular earth with an impervious zone. 
  6. Concrete-face-rock-filled dams: This is a rock-fill dam with concrete slabs on its upstream face. This design provides the concrete slab as an impervious wall to prevent leakage and also a structure without concern for uplift pressure.
  7. Barrages: A barrage is a type of low-head, diversion dam which consists of a number of large gates that can be opened or closed to control the amount of water passing through.
  8. Earth-filled-dams: Earth-filled-dams also known as earthen dams, rolled-earth dams or simply earth dams, are constructed as a simple embankment of well-compacted earth.
