Prioritization of Effective Zones on Peak Flood Discharge Using HEC- HMS Hydrological Model in Sheikh Bahaee dam Basin

Today flood is a destroying natural disaster that sometimes damages natural ecosystems in large scale that are uncompensable. Increasing current of flood occurrence and its financial and human damages has been the cause of studying this subject in regional scale in different areas. It is necessary to simulate hydrologic behavior of watersheds in order to combat flood risk. This study aimes to prioritize of effective zones on peak flood discharge or to distinguish the areas that have more flooding potential in Sheikh Bahaee dam basin located in Esfahan province, kashan township, using HEC- HMS hydrological model. Results showed that areas located near basin outlet play the most important role in flood production and so should have more priority in watershed management practices. The obtained results can be very much helpful to region monitoring system.
