The Shahid Abbaspour Dam (Karun-1 Dam) is a large arch dam providing hydroelectricity from the Karun River; it is located about 50 km northeast of Masjed Soleiman, in the province of Khuzestan, Iran, and originally completed in 1976, and formerly named "Reza Shah Kabir Dam". The Karun-1 Hydroelectric Dam was the first of a series of dams planned for development on the Karun River.
The dam is a double-curvature concrete arch type, 200 m (660 ft) high from the foundation rock. Its crest width is 6 m (20 ft). 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.
The Karun-1 Hydroelectric Dam houses two power stations, one built in 1976 and another built in 1995. Each contains four water turbines connected to electric generators of 250 MW, for a combined generating capacity of 2,000 MW. The dam's electrical output is connected to the national electrical grid, with most generation occurring during periods of peak demand for electricity.
