arch dam An arch dam is a concrete dam that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, causing the arch to straighten slightly and strengthe ...

with a total capacity of 540 megawatts. When built in 1984 it was the third largest dam in Turkey. As more dams have been built, it is the fifth largest. Because of the arch design, the force of water pushing against the dam compacts the dam and strengthens it. The weight of the dam structure pushes it down firmly into the underlying rock. This design is ideal for dams built in rocky narrow gorges.
