.Although many kinds of rainfall-runoff models have been developed by hydrologists, the unit hydrograph methods are still a gainful tool for flood estimation in many basins where recorded hydrological data is not sufficient to support distributed rainfall- runoff models. The aim of this research is to derive the analytical unit pulse response functions of quick and slow runoff of streamflow using a conceptual model containing three serial tanks as well as a parallel hybrid-Chanal tank. The interrelation of the tanks can be shown using exponentially structured models which their parameters reflect the physiographical characteristics of basin. The parameters of model were estimated using direct search optimization method. Efficiency and validity of the developed conceptual model was evaluated for various observed events using statistical criteria such as Nash-Sutcliffe, mean relative absolute error for discharge, peak flow and runoff depth. The result showed that the developed model has good capability for modeling of rainfall- runoff process, especially in peak and time to reach peak has increased.No need to define in terms of excess rainfall and soil moisture conditions before rainfall, are the advantages of the developed model to forecast of runoff that influenced from different storms
