Arid and semi-arid regions of the planet sit in 20 to 45 northern and southern latitudes and are called the global erosion belt. Identification of these regions is thought of as the basic and rational initiation. Tasouki-Rigchah with an area in excess of 131660 hectares expands in the southeastern part of Sistan province with a harsh and dry climate. In this region, sand blasts and mobile sand dunes are threatening and dry spells and following decrease in vegetation cover and drying out of Hamoun lake, along with the winds named One-Hundred-and-Twenty-Days, lay the ground ready for wind erosion and sand blasts. In response, different wind erosion forms like Barchans and Barchanoids have been formed. Studies include speculating local evidences of wind erosion, interpretation of satellite and airborne imageries for different temporal steps, general morphological characteristics of dunes, identification of sand dune types, probing erosive wind attributes, sampling from different faeces and granolometric, morphoscopic and mineralogical analysis. Results obtained from granolometric analysis were used to identify wind speed threshold for erosion. This study set out with the aim of assessing geo-morphological faeces with underlying information obtained through sampling and granolometric analysis.
