The Ten Biggest Dams in Asia
Human’s never ending need of water dates back from the start of our existence. In the earlier days our ancestors have always been relying on the naturally occurring dams found in nature. But with the rapid increase of population, these natural dams are now very insufficient in providing enough water to supply the peoples demand for water.

With a problem comes a solution, our early ancestors needed to find a more efficient way of getting and storing water for their needs. So instead of relying on nature built dams, they have decided to create one of their own which they would have easy access and would supply them water if they needed it.

They have started on creating these fairly small dam, just enough to supply their families with clean water all throughout the year. The earliest dam that was recorded is around nine meters high and has a width of one meter and was supported by a fifty meter wide earth rampart. This is located in Jawa, Jordan a hundred kilometers northwest of its capital Amman.

Today, due to the huge demands of water our engineers have to build these couple of colossal size dams. And because of our technology, we don’t just create them for water supply we harness its power to have electricity and improve our day to day living, use it for irrigation, and a whole bunch of stuffs.

There a lots of huge dams that were created all around the world but in this paper I shall give you The Ten Biggest Dams in all of Asia.
The tenth biggest dams in Asia is called Nagarjuna Sagar Dam this is the biggest masonry dam built in the Krishna River in India. It is four hundred ninety feet high and sixteen kilometers long that has a twenty-six gate with a high of forty-five feet and forty-two feet in width. The total capacity of the reservoir is eleven thousand four hundred seventy- two million cubic meters which is the world's largest man-made lake. Due to the size of this dam the need more than a couple feet of concrete as a wall, it has roughly six feet of concrete to support it massive water pressure.

The dams has an eight unit electricity generating units that yields a power generation capacity of 815.6 MW. Its right canal has three units with a total generating capacity of 90MW and the left has two with a generating capacity of 60MW.

The plan of creating a dam in the Krishna River was forwarded by the British rulers in the year 1903. It was that the suitable locations for the reservoir was in Siddeswaram and Pulichintala. After fifty-three years of waiting the construction finally begun on 1956 which took them approximately four years to contruct. It was finished on 1960 and was opened in the year 1967 by the prime ministers daughter Indira Gandhi.

The construction of the dam submerged an ancient Buddhist settlement named Nagarjunakonda which was the capital of Ishvaku dynasty in the first and second centuries. Before the flooding of the reservoir diggings were done and excavated around thirty Buddhist monastaries as well as artworks and inscriptions that is of great historical importance. The stuffs that were dug up were transferred to the island in the center of the dam and some of them were transferred to the mainland for safe keeping. It also submerged fifty-two villages and around twenty-four thousand people were affected on its construction. As soon as the dam was constructed these people were relocated and was finished on the year 2007.

It is actually the earliest irrigation and hydroelectric plant in India. Nagarjuna Sagar Dams is the one responsible for the supply of water on the Nalgonda District, Prakasam District, Khammam District, and Guntur District. The dams’ right canal also known as Jawahar canal is two hundred three kilometers long and irrigates 1.113 million acres (around four thousand five hundred square kilometers) of land. Its left canal known as Lalbahadur Shastri canal is two hundred ninety-five kilometers and irrigates eight hundred kilometers...
