Abstract :

The purpose of this study is application of MPSIAC model and determination of the role of geology (one of nine MPSIAC factors) in soil erosion and sediment yield in Eshghabad-Sule watershed (SW of Quchan). Information layer of the model that are consist of nine effective factors in erosion and sediment yield in the watershed site were obtained by digitalizing and classifying the basic information data in GIS program. These factors are surface geology, soil, climate, runoff, topography, ground cover, land use, surface and river erosion. Based on geology’s factor (7th of MPSIAC factor) intensity of erosion, in this watershed is low, medium and very low, respec vely. Whereas the final results of MPSIAC model indicate that 82.89 % of the total watershed area is classified at class III of erosion category with medium sedimenta on, and 17.1% is classified at class IV of erosion category with high sedimentation.
