Ghale Ganj basin is Located In southeastern corner of Kerman Province and Kahnuj township. This city is affected by both water and wind erosion. In this study, MPSIAC model is used to estimate the amount of water erosion and IRIFR model to estimate the wind erosion. Results show that the maximum area is consist of high (41 %) and Medium (43.4%) wind erosion classes and residential areas and villages in the area were not secured from the losses and risks. Water erosion is another form of erosion at this basin. Factors such as mean annual precipitation (190.35mm) and favorable geological units (recent deposits, fluvial sediment) have prepared an appropriate condition in order to water erosion. Although the rate of deposition caused by water erosion is high for some fancies, the amount of sediment due to water erosion for the whole area (considering the large size of the basin ) is low (17.19 cubic meters per square kilometer per year) . Performing Physical and chemical operations (Mulching), water weeds control, arboriculture, plant production, biological windbreak and the organization and management of grazing can be some important operations suggested to control desertification in Ghale Ganj region.

Keywords: Wind erosion, MPSIAC model, water erosion, IRIFR model, Ghale Ganj
