Abstract

Finding a particular model that can correctly predict floods at large and sensitive basins like Golestan is critical. Due to being prone to flooding identifying prone areas to flooding and flood production levels according to physical characteristics of the catchment is essential. In this paper hydrologic modeling was performed on the Golestan Basin and we tried to estimate flood hydrograph through both lumped and distributed mathematical models to analyze how close they are to reality from Golestan basin. Formation of precipitation and surface flow after rainfall and formation of hydrograph has been studied using both SCS lumped model and WMS distributed model, and it is identified that distributed model results are closer to the recorded hydrograph of the basin.
