Aim: Wind energy and its change in different directions have a great influence on the morphology and shape of wind erosion facies..
Material & Method: In this research, 20 year statistics of five stations were used to analyze wind direction and sand transport potential in the studied area. The analysis of these data was done in Wind Rose and Sand Ros software.
Finding: At first, the geomorphological map of the sands of the region was drawn, and then the winds of the desired stations were drawn, which indicated that in Aran and Bidgol stations located in the western part of the region, the winds blow from the north, but in Kashan and Garmsar located in the western part and The prevailing northern half of the wind blows from the east. As a result, a small part of the hills in the northern part of Rig e Band- Rig is very active.
Conclusion: The results of the annual storms indicate that winds with eastern and western directions are the dominant winds in Qom, Garmsar and Kashan stations. In addition to the north, these winds also blow from the east and west-northwest directions. At Ardestan station, however, unlike other stations, wind does not blow from the north and mostly from the south. For Qom and Aran Bidgol stations, the highest sand transport potential (DP) is related to the northeast and southwest directions. For Kashan station, the directions are between south and west, while for Garmsar station, the direction is different from other stations and between southwest and northwest. In Ardestan station, the highest one is related to the southwest direction.
Innovation: . In this research, Analysis of the sand drift potential and their paths help us interpret the formation of the ridges elsewhere.
