Wind erosion occurs all over the arid, semiarid, sub humid and even humid regions of the world and it sparks extensive damage. There are different methods for wind erosion estimation worldwide. One of the main and applicable methods for wind erosion estimation in Iran is IRIFR method (Iranian method). Wind erosion rate is calculated using 9 factors in this method. This research was done in Tasouki-Shileh region in Sistan plain. A series of work units were needed to performed this task. Work units according to Ahmadi method were determined and were separated. In total, 2units, 3 types and 17 faces of Geomorphology were identified in Tasuki-Shileh region. These faces are located in pediment and playa geomorphology units. Then, the scores of 9 factors affecting wind erosion in studied region and total geomorphology faces were determined. For this purpose, all geomorphology faces scores in relation to all factors affecting on wind erosion were calculated. Total obtained scores in each faces and all studied region that was presented by table format using model, lead to calculating wind erosion intensity or classes in region and all geomorphological faces. The results showed that 2.62%, 17.48%, 49.74% and 30.16% of region area have low erosion, medium erosion, high and very high erosion respectively.
