Wind erosion is considered as one of the most important factors for lack of development in arid and semi-arid regions. For this reason identification of effective factors on wind erosion as well as determining the potential of wind erosion in an area is one of the main management initiatives that can be done to control and reduce the negative effects caused by this phenomenon. The case study in the present research is a part of Mokhtaran watershed located km away from the west part of Sarbisheh Township, South Khorasan Province between ' to ' E and ' to ' N geographically. To determine and estimate the potential of wind erosion in agricultural and non- agricultural lands, experimental methods of IRIFER, IRIFER and Arc GIS software were applied. To achieve this objective topographic and geological maps of the study area, as well as Digital Elevation Model (with the resolution of m), satellite and Google earth imageries and available information related to the objectives of this research were obtained from the data achieve of Jihad-e- Agriculture and Governate of South Khorasan. Following field visits to the study area the scope of application for each model (non-agricultural lands using IRIFER and agricultural lands using IRIFER) was determined and for attaining more accuracy homogeneous units and geomorphology faces of the area were identified using the guidelines presented by Dr. Ahmadi. Following this step, the scores for the nine factors of each of the applied models was determined. Due to the importance of wind erosion, the potential of wind erosion and its intensity were specified and the wind erosion intensity maps were mapped finally. The results indicated that among agricultural lands, gardens and among non-agricultural lands, deposits faces from stream bed had the least intensity of wind erosion. Also dry lands and sandy lands had the most wind erosion intensity. Furthermore wind erosion intensity in agricultural lands is less than non- agricultural lands based on the results of this study.
