DAMS IN INDIA    

There are 3200 reservoirs and dams in India are constructed in India by the year 2012. In this article, we provide you complete information of dams in India in this Article

First of all, You Must To Know  what is a dam So Lets Begin’s

What is a Dam:

The dam is in a barrier constructed In The Path of River, Lake Or Reseviour and raises its Water level, forming a big Water reservoir Which Is Further used to generate electricity or as a water supply.

             The water is stored in a very vast reservoir, and on the mouth of the reservoir, a massive wall is constructed which is opened when a large amount of water is stored in the reservoir or when there is a need for water. Thus this was a brief explanation of dams and about their construction.

 

Why Are Dams Created: 

 Dams are not created for one purpose, there are many advantages for constructing a dam such as the water stored in dams could be used all over the year for irrigation purposes.

The construction of dams also promote the aquatic life, the dams also help the industries by the water, the water stored in dams also satisfies the consumption of human beings, and the best thing of dams is that they provide a massive opportunity by generating electricity. These Dams Are Built by Big Companies With the help Of the Indian Government. time to time government released the latest jobs for these projects.

             There are two primary purposes of creating the dams first to use the collected water, which is distributed respectively. The second purpose is to retain the water and to prevent the proper flow of water in every region. The basic requirements which are fulfilled by the creation of dams are power generation, proper water supply, to stabilize water flow, for irrigation in fields, for flood prevention, for land reclamation, and also for the water diversion

Importance Of Dams: 

             As we all know that there are many places all over India or all over the world where there is always a lack of water not only for an industrial or irrigational purpose but also for the basic human needs. Thus, if dams are constructed near these areas, then the needs related to water could be satisfied. The main purpose of the construction of dams is to provide water to people for satisfying their basic needs all over the year. There are 36 countries that also not have water to drink. And there is about 23% of the Indian population which is living their life without electricity. Thus the construction of dams could satisfy people in various ways.

Types Of Dams In India:

             We had known quite a lot about the dams now it is the time to know about the types which are basically seen in India and all over the world. There are seven types of dams in India which are given as below: –

  1. Diversion Dam
  2. Buttress Dam
  3. Embankment Dam
  4. Cofferdam
  5. Storage Dam
  6. Detention Dam
  7. Gravity Dam

 

1). Diversion Dam:

 The role of the diversion dam is easily understood by its name. The diversion dam is a type of dam which is used for diverting the direction of the flow of water. These types of dams are constructed on a particular height, and when the water comes out from the height, it is at quite high speed, and by the direction made in front of the gate, the water turns in that particular direction. These types of dams are used to change the direction of water and supply it to the place where the water is demanded.

 

2). Buttress Dam:

This type of dam is constructed by making a wall on the mouth of the reservoir, and this wall of a dam is supported by the multiple types of supporters, which are also constructed with the help of the reinforced concrete. And these supporters of the wall are known as buttresses and these buttresses are put alternatively by an even interval. On the basis of the quality and design of the buttress, the buttresses dam in India could be classified into three types: –

a). Multiple Arch Type Buttress Dam

b). Massive Head Type Buttress Dam

c). Deck Type Buttress Dam

  These are the three types of Buttress Dams in India

 

3). Embankment Dam:

The embankment dam is the third type of dam in India. The Embankment dam is quite a large type of dam which is being artificially made by the waste materials of industries, also with the natural raw materials. The wall of this dam is created such that it acts as a semipermeable membrane. Basically, the wall of the dam is either made of earthly material or of the rocks on the basis of the material used in them; they’re classified into two ways: –

a). Earth Filled Embankment Dam

b). Rock Filled Embankment Dam

These are the two types of Embankment dams in India

 

4). Cofferdam: 

The cofferdam is a type of dam which is established on a place temporary for the construction of pillars of bridges. This type of dams are constructed by enclosing an area, and then the water of that particular area is pumped out, and when the place gets dry, the work of construction is done there, and then the cofferdam, which was constructed is removed. The cofferdams are basically used for the construction of bridges and other structures to be built within the water.

There are six types of cofferdam in India which are given below: –

a). Earthen Cofferdam

b). Rockfill Cofferdam

c). Single-walled Cofferdam

d). Double-walled Cofferdam

e). Braced Cofferdam

f). Cellular Cofferdam

These were some basic types of Cofferdams in India

 

5). Storage Dam:

The storage dam is the fifth type of dams in India. Instead of all the things, the Storage dams are the most basic dams in India. The role of storage dams is clear from its name only. In the storage dams, the water is filled by the rain in the rainy season, and then this water is stored in these dams, and then the water stored is supplied to the local area, and when the water is supplied from these dams, hydroelectric power is generated. The water stored is also used for irrigation for the whole year. The storage dam is the most common type of dam in India.

 

6). Detention Dam:

The detention dams are another kind of dams in India which are specially constructed to control the flood and the destruction caused by it. These dams are constructed to store the excess amount of water and use it by the whole year as per requirements. The water which is retained by rain is gradually released. Commonly these dams are constructed on those places which are in high rain order and are flood affected. These are also commonly used dams in India

 

7). Gravity Dam:

The gravity dams are massive dams that are constructed in order to store a large amount of water, and this is made that much strong that it could easily resist the pressure of gravity and which is applied by the water on the walls of the dam. This dam is constructed with the help of quite a thick layer of the reinforced concrete, and this makes a gravity dam more stable than any other type of dam. The construction of a gravity dam is such strong that they remain unaffected by earthquakes.

                   These are some of the main types of dams in India. The types of dams given above could be seen easily in India because these are the most common types of dams in India. There are many advantages of establishing dams as they are very useful as the conservation of water is very necessary for domestic use, for industrial purposes, and also for the generation of hydroelectric power.
