largest dam in india

Largest dam in india Welcome everyone to read today’s post. Today we will learn about some of the largest dams through this poster. It is very important that we all have more or less knowledge about dams. Because in this regard there are various types of tests ie – from SSC exams to general awareness sections of bank exams, there are questions on various topics like politics, geography, sports and many more.

Dams are an important issue, even in a general awareness sense. Because in many government exams including bank exam, SSC exam, RRB exam etc. questions related to dams are seen again and again. So it is understood that it is important for all of us to have an idea about dams. So without further ado let’s get to know about it in detail.

What is the Dam?

Dams are barriers that impede the flow of water, creating reservoirs. These structures are primarily constructed to generate hydroelectricity using water. Reservoirs created by dams serve several purposes, including flood control, irrigation, human consumption, industrial usage, aquaculture, and navigation.

Types of Dams

India boasts numerous dams, making it crucial to familiarize oneself with them as they often appear in various exams such as IBPS or SBI. Dams can be classified based on their structure, and the different types are outlined below:

Arch Dam

This is a concrete dam that curves upstream in the plan. The hydrostatic pressure of the water against it pushes against the arch, strengthening the structure as it pushes into its foundation or abutments. It is most suitable for narrow canyons or gorges with stable rock walls.

Gravity Dam

These dams are constructed using concrete or stone masonry and hold back water using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of the water pushing against it. Each section of the dam is designed to be stable and independent of the others.

Arch-Gravity Dam

This dam has the characteristics of both an arch dam and a gravity dam. It curves upstream in a narrowing curve that directs most of the water pressure against the canyon rock walls, reducing the lateral force acting on the dam.


This type of low-head, diversion dam consists of a number of large gates that can be opened or closed to regulate the amount of water passing through. It helps regulate and stabilize river water elevation upstream for irrigation and other systems.

Embankment Dams

These are large artificial dams created by compacting a complex semi-plastic mound of various compositions of soil, sand, clay, or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core.

Rock-Fill Dams

These are embankments of compacted free-draining granular earth with an impervious zone. The earth utilized often contains a high percentage of large particles.

Concrete-Face Rock-Fill Dams

This is a rock-fill dam with concrete slabs on its upstream face, providing an impervious wall to prevent leakage and a structure without concern for uplift pressure.

Earth-Fill Dams

These are constructed as a simple embankment of well-compacted earth. They may be entirely constructed of one type of material but may contain a drain layer to collect seep water.

Major Dams in India

India’s significant dams have contributed significantly to the well-being of its residents by providing ample benefits, including:

Meeting the demand for water for domestic, industrial, and irrigation purposes.

Generating hydroelectric power and facilitating river navigation.

Serving as recreational areas for fishing and boating, thanks to their reservoirs.

Assisting in reducing the impact of floods.
