Flood
has caused financial and vital damages in the Hajighoshan watershed in recent decade.In
this study, we investigated the
efficiency of flood control structures in decrease of flood hazard and their
effects in the downstream flow regime.
First, a rainfall-runoff model has presented by using HEC-HMS model.The
rainfall- runoff model was presented and optimized by using 5
past flood events and then was validated with 4 another flood events.The
dams were simulated by using Elevation-Area method in the validated rainfall-runoff model. The
results showed that The efficiency of flood control dams in decreasing of flood
hazard dependents on their location, reservoir volume and the surface of watershed or sub-basin which it controlled its runoff. |
