Tarbela Dam is significant for being the biggest dam and being highlighted among the world’s top five dams due to its construction. It was constructed in 1976 and is approximately 470 feet (143 meters) high.
Tarbela Dam has an artificial barrier referred to as Tarbela Lake. The lake is based on a surface area of 250 square kilometers. Tarbela Dam is filled with water from three different rivers: Ravi, Sutlej, and Beas.
Currently, the Tarbela dam can reserve around 6,800,000 acre-feet and discharge up to 18,406 cubic meters per second. Five of the largest tunnels were built on the dam to regulate the flow of water.
Often, the question arises of what an earth-filled dam is.
Is Tarbela Dam earth-filled?
In simple words, an earth-filled dam is an artificial embankment that reserves water. The structure is built by forming a mound-like surface by combining raw materials like rock, clay, sand, and soil. Hence, the Tarbela Dam is an earth-filled terrain that is used as a multi-purpose reservoir.
