چکیده | ||
Constructing of control structures, like dams, change temporal and spatial unequal distribution of water ,and also play an effective role in reduce or eliminate of damage that caused by floods. So reservoir dam’s effect on floods discharges reduction must be determined. In this study the rain Information and flood hydrographs were used to check the flood routing for previous period of Maroon dam constructing, with using ANNs. The effect of Maroon dam Constructing, on peak of flood reduction were specified. ANNs has Indicated that it can predict flood hydrographs at testing phase as well. Comparison of the predicted and observed hydrographs in Behbehan hydrometric station showed that, for the most severe floods during the considered period, the dam was able to control the flood and to reserve about 121.74 MCM. Also the peak flow was decreased from 1975 m3/s to 500 m3/s. | ||
