Dams are well known for power generation. Many other purposes are fulfilled by Dams like irrigation of farmlands, and also dams play a very vital role in the prevention of floods. The very biggest part of the land is acquired by Dams. It is also a source of fish farming and many tourists visit Dams. Dams are also the real models of engineering. Dams are nonrenewable sources of energy. Billion Dollars are required to build a Dam. There are many Dams in the world out of them some the special due to the reservoir, technology, power production, etc. In this technology Blog, we will discuss the Biggest Dams Worldwide.

Tarbela Dam

This is the biggest Dam in the World, it is located in Tarbela, Khyber Pakhtunkhwa, Pakistan. Its construction cost is $1.497 billion and was completed in the Year 1976. Its total capacity is 138,600,000 square yd. Its height is 143 meters. The total length of this Dam is 2,743 meters. This is also the largest earth-filled Dam in the entire world. By volume, it stood in the fifth position.

The purpose of  Terbela construction is to control the flooding from the Indus river. Millions of farmers are benefited from this dam because it irrigates huge land. Now many phases of Terbela are in working mode and generating a huge amount of power. A large amount of power demand in Pakistan is fulfilled by this mighty dam.

Aswan Dam

This is the largest dam in the world according to the reservoir by volume. It is located in Egypt. It is situated on the famous river Nile. The power generation capacity of this mighty Dam is around 2100 MW. It is also the biggest source of agriculture in Egypt and also the largest power producer in Egypt.

Fort Peck Dam

This Dam is located in the Missouri River, Fort Peck, Montana. It was completed in 1993. Its construction cost is $ resorvier volume 125,628,000 cu yd. The height of this Dam is 76.4, and its length is 6409 meters. It is the largest Dam hydraulically filled in the United States.

Ataturk Dam

This dam is located in Sanlıurfa-Adıyaman, Turkey. It was completed in the year 1983. Its construction cost is about $1.25 billion. Attaturk Dam’s total capacity is 110,521,827 square yd. Its height is 184 meters and its length is 1820 meters. It is the largest Dam in Turkey. It provides irrigation, flood control, and power to both Turkey and Syria. Its name is related to Mustafa Kamal Ataturk. Ataturk Lake is created by this Dam and this lake is the biggest source of food and water.

Houtribdijk Dike

This Dam is located in Lelystad, Netherland. It was completed in the year 1975. Its construction cost is about $64 million. Its total capacity by volume is 68 meters in width, with a height of 13 meters and a length of 30,000 meters. This Dame connects to major cities Lelystad and Enkhuizen and carries approximately 8,500 commuters and travelers per day. It is also the biggest source of tourism in the Netherland. It runs about 13km and two cities are connected by this Dam. This Dam also contributing to the revenue of the country.

Oahe Dam

This Dam is located in South Dakota, USA. It is completed in the year 1962. Its construction cost is $340 million. Oahe Dam Total capacity is 93,122,000 cu yd with a height of 13 meters, and length is 30,000 meters. This Dam was authorized by the flood control Act of 1944, and construction started in 1948. World-first rock tunnel the boring machine was invented for this great project.

The famous president of America John F. Kennedy dedicated the dam in 1962. These benefits are provided by this Dam like Flood control, power production, irrigation, and also navigation benefits. So Dams provide a positive impact on societies due to their benefits. These are the world’s largest Dam many other Dams also exist but as discussed above Dams are mighty. Countries like China, India, the USA, Brazil also have great water reservoirs which are known as Dams.

How Dams Work.

Dams are the biggest source of electricity. It is a non-renewable source of energy. Water is stored in the big reservoir surrounded by great walls along with tall mountains. Then stored water is passed through one path known as spillways comprised of big turbines when water passes through the turbine it rotates and then the turbine shaft is attached to the generator. The generator’s function is to produce electricity. After that generated power having low voltage is passes through the unit transformers then voltages are step up for transmission purposes.

Then power having high voltages and less current is transmitted over long distances and reached to our neighboring grids where power is distributed as per power demands. In transmission, the current is low to avoid current losses. This is the whole phenomenon of power generation. Dams also avoid floods and are also a great source of entertainment for visitors.
