The '''Dez Dam''' ({{lang-fa|سد دز}}), formerly known as '''Mohammad-Reza Shah Pahlavi Dam''' (Persian: {{lang|fa|سد محمدرضا شاه پهلوی}}), before [[1979 Revolution]], is an [[arch dam]] on the [[Dez River]] in the southwestern province of [[Khuzestan]], [[Iran]].

The '''Dez Dam''' ({{lang-fa|سد دز}}) is a large [[hydroelectric dam]] built in [[Iran]] in 1963 by an Italian consortium.

[[Impregilo]] was involved with building the Dez Dam. Plans for the dam were finalized in 1957 and construction began in 1959. In 1962 the first generator was commissioned. In 1963 the dam was complete with two of the eight 65 MW [[Francis turbine]] generators commissioned. The remaining six were commissioned by 1970.

The dam is on the [[Dez River]], the closest city being [[Andimeshk]] the only way to access the dam in the Northwestern province of [[Khuzestan]]. It is 203 metres high, making it one of the highest in the world, and has a reservoir capacity of 3,340 million cubic meters. At the time of construction the Dez Dam was [[Iran]]'s biggest development project. From [[Andimeshk]] it is 15 minutes easy drive.

It is also possible to visit powerhouse which is located at the left of the dam in the mountains. The powerhouse has eight vertical Francis turbines.

The dam's current problem is the annual loss of reservoir capacity due to the erosion of soil in upstream areas. It has no educated engineers to remove sludge and clean the lake on regular basis. {{Fact|April 2009|date=April 2009}}

[[Impregilo]] <ref>[http://www.ilisu.org.uk/impregilo.html Ilisu Dam Campaign]</ref> was involved with building the Dez dam, Iran’s highest. The water from the reservoir went to irrigate 160 square kilometres, only one-fifth of the area that the dam’s designers claimed would be irrigated. The irrigated land was largely for the benefit of foreign agribusiness corporations, including Mitsui, Chase Manhattan, Bank of America, Shell, John Deere and Transworld Agricultural Development Corporation. About 17,000 farmers lost their land to agribusinesses. Years later, many were still landless and jobless. Until the overthrow of the Shah in 1979, all the foreign companies left the area.
Dez Dam has now an official web page and visitors are advised to visit the page and get more exact information.

The Dez Dam (Persian: سد دز), formerly known as Mohammad-Reza Shah Pahlavi Dam (Persian: سد محمدرضا شاه پهلوی), before 1979 Revolution, is an arch dam on the Dez River in the southwestern province of Khuzestan, Iran. It was built between 1959 and 1963 during the rule of Mohammad Reza Pahlavi, the last Shah of Iran, with contacting an Italian consortium and is owned by the Khuzestan Water & Power Authority.[3] The dam is 203 metres (666 ft) high, making it one of the highest in the country, and has a reservoir capacity of 3,340,000,000 m3 (2,710,000 acre⋅ft). At the time of construction the Dez Dam was Iran's biggest development project. The primary purpose of the dam is hydroelectric power production and irrigation. It has an associated 520 MW power station and its reservoir helps irrigate up to 80,500 ha (199,000 acres) of farmland. US$42 million of the cost to construct the dam came from the World Bank.[4][5]

Background

[edit]

Impregilo was involved with building the Dez Dam. Plans for the dam were finalized in 1957 and construction began in 1959. In 1962 the first generator was commissioned. In 1963 the dam was complete with two of the eight 65 MW Francis turbine generators commissioned. The remaining six were commissioned by 1970. In the late 1970s the irrigation of the project had reached 80,500 ha (199,000 acres) of its 110,000 ha (270,000 acres) goal.[4][5][6]

The dam's current problem is the annual loss of reservoir capacity due to the erosion of soil in upstream areas. By 2006, the reservoir volume was estimated to be 2,600,000,000 m3 (2,100,000 acre⋅ft)[7]
