History and background

The preliminary studies of Karun 4 Project were carried out in 1967 in the frameworks of water resources development project and general planning of Karun River catchment area resources by Harza International Consultant. The contract of first and second phases of project studies, which is concluded between Mahab Qods Consulting Engineers and IWPC, is in its final stage. It should be mentioned that due to complexity of the project during second phase studies, the French Company of Koine Bleiye has also supervised and approved the project studies as the assistant company.


Location and general layout

Karun 4 reservoir dam is located in Charmahal & Bakhtyari Province with 180 kilometer distance to south-west of Shahrekord City and 4 kilometer distance to downstream of Armand and Bazoft Rivers conjunction.


River specifications

Karun River is the most watery and the longest river of Iran which originates from Zagros Chain Mountains. In downstream of Gatvand diversion dyke this river enters into Khuzestan Plain and finally joins Persian Gulf. In recent decades electricity generation potential of this river is highly taken into consideration and expanded efforts are carried out for actualization of this potential. One of these efforts is construction the Karun Dams Series for controlling floods of this river and generating hydroelectric energy.
