Flood is one of the major hydroecological phenomena that in each period causes damages to human achievements. Therefore, controlling this phenomenon is the subject of many researchers' works and studies specially hydrologists who have tried to predict the flood`s possible behavior by modeling it. This paper is trying to help one of the most widely used methods to estimate the maximum discharge in one of important catchment basins in Iran. So using the Dimensionless Unit Hydrograph method that is released by the Soil Conservation Organization of America, and according to the history of rainfall in each region, the likely quantitative estimates of flood volumes can be presented in each season. Although parameters in this method are diverse and frequently correlative, the results give accurate estimates of the flood discharge that are consistent with the input data. So in this study, to calculate the maximum discharge based on SCS method, numerical modeling has been used in a Matlab program and for this purpose, the 24-hour flood data at a four-year time period has been imported. At the end, to link the precipitation of maximum discharge using a weight-bearing function, a mathematical equation with the best adaptation with each subbasin’s data was extracted which can substitute with the lengthy equations in the intended area.
