Geomorphological landscapes are the foundations of natural resources investigations of the watersheds. The results show that the study area is geomorphologically composed of mountain units (mountains and hills) and plain (types of eroded and covered plains). The results show that the mountain unit is 28%, which includes mountains and hills including the Middle Eocene, Upper Eocene (Lower, Middle and Upper) and Oligocene and Pliocene satellite hills. The plain-head geomorphology unit in the study area has an area of 50384.71 hectares, which occupies 71.114% of the area. Geomorphological type of erosion plain with 2 geomorphological facies. The geomorphology type of the plain head of the upandage of two geomorphological facies and the type of the covered plain head have been identified in the study area of 16 geomorphological facies. In the covered plain type, wind erosion has been predominant in most of the facies. Most of the area is composed of abandoned plains (56%) due to residential areas, rangelands and abandoned agriculture. From the facade point of view, most of the area consists of small and medium grain sandy plains with low to medium density and agricultural lands.Geomorphological studies have been considered as the basis and basis for other studies in the preparation of desertification executive plans. Using all studies of basic or physical resources and socio-economic studies, which are collectively referred to as biophysical resources, planning will be done to deal with desertification in each of the geomorphological facies.
