AbstractBakhtegan lake basin with area of 27220 km2 is located in the central plateau of Iran. One of the main problems in

this area, especially in southern part is seasonal floods. At 1972, 2005 and 2006 three storage dams with the total

capacity of 1688 MCM were built at the upstream branches of Kor and Sivand two main rivers of the basin.

Considering these three dams the basin could be divided into 7 sub basins. Simulating the dams operations for

probable precipitation model in the area and doing reservoir operation for these dams, the flood amount in the

intersection point of these two rivers is minimized. Considering this strategy and exploitation’s priorities, rule and

decision curves were supplied for the common exploitation of dams. Considering rainfall records in the area,

operation of this curves were simulated for 30 years period based on real records. The results show that this

software work with the existing hardwares, reduce the maximum inflow of flood for 30% and prevent the area from

the flood damages.
