Land assessment for the purpose of identifying and zoning areas sensitive to slope movements is a research related to geomorphologists. The area of this basin is 8226 hectares. The studied area is located between the geographical coordinates of 07, 20, 46° to 30, 46° east longitudes and 17, 28, 38° to 52, 33, 38° north latitudes. The main objective of this study is to identify the factors affecting the occurrence of landslides and to zone landslide-prone areas. Therefore, to assess and identify high-risk areas, 9 factors affecting the occurrence of landslides were used, including distance from the watercourse, lithology, soil, slope, slope direction, elevation classes, precipitation, land use, and distance from the communication road. Multi-criteria decision-making algorithms were used to assess and zone the risk of landslides. The results show that the slope factor has the highest weight. Examination of the zoning map using the MACBETH model shows that 4.58, 12.25, 25.01, 39.34 and 18.78 percent of the area of the study area are located in the very high, high, medium, low and very low risk zones, respectively. The results of the performance evaluation of the MACBETH model indicate an acceptable accuracy of this model in predicting landslide zoning. The area under the curve (AUC) value for the training data is 0.86 and 0.88 for the validation data, which indicates the appropriate performance of the model in both data sets and its high ability to distinguish landslide-prone areas from non-prone areas.
