In this study, different methods were applied to simulate the rainfall–runoff process over the Kasilian Watershed located in the Mazandaran Province, in northern Iran. The study was intended to compare the accuracy and reliability of a geomorphologic model with Snyder, SCS, Trianglar, Rosso and Geomorphoclimatic Unit hydrographs, and in addition to determine the shape and dimensions of outlet runoff hydrographs. The peak time and peak flow of outlet runoff in the models were then compared, and the model that most efficiently estimated hydrograph of outlet flow for similar regions was determined. The study's results confirm the high efficiency of the Geomorphoclimatic Unit Hydrograph and its ability to increase simulation accuracy for runoff and hydrographs
