The Karun-3 dam is a hydroelectric dam on the Karun river located in the province of Khuzestan, Iran. It was built to help meet the Iran's energy demands as well as to provide seasonal flood control.[2] The Karun river has the highest discharge slits and seasonal flooding in Iran.[3]

The Karun-3 power generators are connected to the national power grid network. At the peak power generation, the generators capacity is 2,280 MW,[4] and average annual electric power generation is 4,137 GWh. This dam has one of the largest generator capacity in Iran which help the electric power shortage during the peak usage at the summer time.

This dam is of concrete double arch type. It is 205 m (673 ft) high from the foundation and 185 m (607 ft) high from the river bed. The foundation width is 29.5 m (97 ft).[5]

The arch dam design is ideal for this location which has a narrow, rocky gorge behind the water reservoir. Moreover, because of its arch shape, the force of the reservoir water presses downward against the dam which strengthens the dam foundation.[6]
