Tarbela Dam on the Indus River in Pakistan is the second largest dam in the world by structural volume and the largest earth filled dam in the world.
Mid-City Club member Glen Truscott, an expert in geotechnical engineering, worked on the construction of this project which opened in 1974.
Glen gave a fascinating insight to the challenges faced by the workers who built this massive dam which stands 148 metres (486 feet) high. The main dam wall, built of earth and rock fill, stretches 2,743 metres (9,000 ft).
The catchment area upriver of the Tarbela Dam is spread over 168,000 square kilometres (65,000 sq mi) of land largely supplemented by snow and glacier melt from the southern slopes of the Himalayas.
The dam has a surface area of about 250 square kilometers and about 82,000 acres of land was acquired for its construction. The large reservoir of the dam submerged 135 villages, which resulted in displacement of a population of about 96,000 people.
The hydro-electric power station can produce 3,478 megawatts of power.
