Undoubtedly, soil conservation programs through the integrated management of watersheds, preventing erosion and maintaining an effective will be a valuable resource. In the Soil Universal Soil Loss Equation (USLE) ,soil erodibility is estimated by nomograph.The soil texture, field capacity moisture, organic carbon content and very fine sand content of each sample was determined. Soil erodibility is measured in different methods. Simulator is the simplest and easiest methods. The results showed that there is a little correlation between K wischmeier and k simulator While the K simulator has a high correlation with k bisal. This methods measure the erosion rate in the first stage. Rain simulation system used for the application splash erosion. Splash erosion is recognaized as the first stage in the process of soil erosion. Basic processes in erosion disperse soil particles by rain drops and changes caused to the soil structure which are moved by runoff.
