Statistics were not required in the absence of erosion and sediment delivery(SDR) and deposition in the watershed basin of Iran is considered the most important problems,Actually hinder the proper planning, especially for the preparation and implementation of watershed management plans are. Determine any areas of erosion and deposition as one of the first steps is for watershed management.Erosion and sediment materials from different directions are considered. It is important that the loss of fertile land into agricultural fields to barren deserts, filling reservoirs and dams, irrigation canals and filling the land is cultivated with new sediment. The purpose of this study to determine the most appropriate experimental method to estimate the SDR using the EPM and the physical properties basin.In this study, many experimental methods to determine that the SDR was assessed according to three criteria, the mean, standard deviation and coefficient of variation Renfro(1983) method was chosen as the experimental method
