COMPARISON OF ESTIMATED FLOOD HYDROGRAPHS USING LUMPED (SCS) AND DISTRIBUTED MODELS (WMS) (CASE STUDY: GOLESTAN BASIN), IRAN

Vaheid Shabanlou, Saeid Shabanlou and Ahmad Rajabi

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 areas prone to flooding and flood production levels according to physical characteristics of the catchment is essential. In this research, hydrologic modeling that was actually performed on the Golestan Basin, flood hydrograph tried that 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 the distributed model results are closer to the recorded hydrograph of the basin.
