Research has found that in Iranian desert regions the unsurpassed way to deal with wind erosion might be bringing the detachment area’s erosion to a halt. In addition to less cost of coping with wind erosion at the detachment area, the chance of success might be higher though some deposition areas have faced up with a high devastating force of wind shear that mitigation in these regions is of higher priority. Hence in the current work we are seeking to identify hazard zones of wind erosion in Zabol district and priority them. In order to identify hazard zones in Sistan plateau, source tracking of sand dunes in Iran (Ekhtesasi-Ahmadi proposed method) was conducted. This method considers influential factors in determining detachment regions and encompasses a regular and step-wise path to identify detachment, transportation and deposition zones of wind erosion. To track the source areas different criteria were regarded as field observatories and questionnaires, morphological analysis of sand dunes, and analysis of wind regimes to ascertain the prevailing winds. According to the studies this was concluded that Sistan plateau which spans over 15197 square kilometers encloses about 145303 hectares of hazard zones distributed mainly in Jazinak, Niatak and Tasouki-Rigchah. To priority them according to the infrastructures under effect Jazinak comes top and is followed by Niatak and Tasouki-Rigchah.
