The Shahid Abbaspour Dam (Persian: سد شهید عباسپور), formerly known as Great Reza Shah Kabir Dam (Persian: سد رضاشاه کبیر) before the 1979 Revolution, is a large arch dam providing hydroelectricity from the Karun River; it is located about 50 kilometres (31 mi) northeast of Masjed Soleiman, in the province of Khuzestan, Iran, and originally completed in 1976.

[3] The dam is a double-curvature concrete arch dam, 200 metres (660 ft) high from the foundation rock.

[4] The arch dam design was chosen for the narrow, rocky gorge where it is located.

The double-curvature arch design withstands the pressure created by the reservoir with a minimum of concrete, because the shape transmits the force of the reservoir downward and laterally, against the rock foundation; this has the effect of strengthening the dam concrete and its foundation by keeping it in compression.

Each contains four water turbines connected to electric generators of 250 megawatts (340,000 hp), for a combined generating capacity of 2,000 megawatts (2,700,000 hp).
