Generally, the influence of temporary rain fall on runoff response may be simulated by a hydrograph. In this research study, based on statistical model, for evaluating the temporary rain fall hydrograph on run off peak, by considering two specified rain fall and producing a runoff model, simulation has been done in a small basin. The mathematical model, namely SEBRM, derived from primary data of two rainfall events and produced runoff of SepidroudBasin, reconstructed and a hyetograph is simulated by two certain rainfalls and calibration of obtained data would be the basis of evaluating of future runoff. The results show the SEBRM model in low and moderate rainfalls intensity, submits very closely convergence between actual and predicted data for describing the role of rainfall volume in producing runoff in small basins. So, in this research study, the error in computations, for maximum 60 mm/h rainfalls intensity, was 13% for SepidroudBasin approximately.
