Evaluation of watershed management on flood forecast lead time in golabdare-darband basin
Author : Mohammad Ebrahim Banihabib and Azar Arabi
The main purpose of this research is to estimate the effect of watershed management on flood forecast lead time in Golabdare-Darband basin using HEC-HMS model. The model was calibrated and validated for Golabdare-Darband basin before and after watershed management.Two observed flood and storm events are used for calibration of model. Firstly, the 25-year flood peak (for the before watershed management) was selected as a flow threshold for flood warning. Then the basin floods were simulated in different return periods in both conditions of before and after watershed management. The results of this research show that the land use change caused by watershed management, increases flood forecast lead time. Furthermore increasing in return periods causes reduction in forecast lead time.
