To determine and locate of the flood-prone areas, effective flood factors in every sub-basin through the flood control studies can play an important and indispensable role in better management of large ecosystems. In this study, the priority of basin flood control operation was done by applying different parameters such as Digital Elevation Method cell size, runoff curve number in three ground moisture, calculation of unit hydrograph with two different method, and presence or absence of depression storage were examined. The result showed that without the presence of depression storage in sub-basins, the effect of Digital Elevation Method cell size and time concentration on potential flooding in the basins, is very negligible in comparison with the runoff curve number parameter but with the increase of depression storage rate; in addition priority is changed and the effect of other parameters on flood basins are increased.
