List of Important DAM in India. That can be asked in your Defence Examination.

List of Important DAM in India:- The questions in the General Awareness section of the defence exam cover topics such as political history, geography, sports, and many more. Knowledge of dams is one of the most important topics tested in the G.A section. General Awareness is a major component of all government defence exams, including NDA, CDS, MNS, INET, AFCAT Etc. In this section, you will find questions based on current events or static topics. As a result, we must first gain a thorough understanding of the Dams. Candidates can prepare more easily by the list of Dams in India provided below.

What exactly is the Dam:-

A dam is a structure that restricts the flow of water, resulting in the formation of a reservoir. Dams are primarily constructed to generate electricity through the use of water. Hydroelectricity is the name given to this type of electricity. Dam-created reservoirs not only prevent flooding, but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigation.

Types of Dam:-

There are many dams in India, so knowing about them is important because there are questions about dams in India. This section is covered in defence examinations like NDA, and CDS.

Dams are classified into the following types based on their structure:

Arch Dam:- A concrete dam that is curved upstream in the plan is known as an arch dam. It is designed so that the hydrostatic pressure (the force of water against it) presses against the arch, straightening it slightly and strengthening the structure as it pushes into its foundation or abutments. An arch dam is best suited for narrow canyons or gorges with steep, stable rock walls to support the structure and stresses.

Gravity dams:- These are dams that are made of concrete or stone masonry. They are intended to withstand horizontal water pressure by using only the weight of the material and its resistance to the foundation. These are built so that each section of the dam is stable and independent of the others.

Barrages Dam:- It is a type of low-head diversion dam that consists of a series of large gates that can be opened and closed to control the amount of water passing through. This enables the structure to regulate and stabilise the elevation of river water upstream for use in irrigation and other systems.

India’s Major Dams:-

The major dams in India have aided the people in a variety of ways, including:

  1. Providing enough water for domestic, industrial, and irrigation needs.
  2. Production of hydroelectric power and river navigation
  3. These major dams in India, as well as their reservoirs, provide recreational opportunities for fishing and boating.
  4. They have contributed to the reduction of floods.
