Soil erosion is a process that directly and indirectly threatens basic water and soil resources. Thus, one of the main problems in planning for the exploitation of water and soil resources is the lack of necessary statistics, especially in small watersheds. The PSIAC model was proposed by the Water Management Committee in the United States in 1968. Influential factors in MPSIAC model are Surface geology, Soil, Climate, Runoff, Topography, Land cover, Land use, Surface erosion and River erosion. The correlation between the factors of soil erosion and texture varies from weak to very good, while the relationship between the factors of runoff and climate, river erosion and soil surface erosion, land use and slope, and soil surface erosion and slope, runoff and sedimentation rate, and geology and slope varies from very good to good. The marly formations in the region are more sensitive to erosion. Due to the amount of rainfall in this region, it has a high vegetation cover. However, due to the change in land use from pasture to rainfed, as well as excessive livestock grazing that exceeds the capacity of the pasture, this has caused soil erosion and intensified it
