Identification of landslide hazard zones in rural settlements of Darab city

Due to the negative effects of landslides on rural and urban settlements and natural resources, identifying areas prone to landslides is very important to prevent such damage. In the northern part of Darab city, shale formations are exposed to severe erosion and have caused previous landslides in the area. has done. 21 villages of rural settlements are located in the same area. Therefore, it seeks to identify endangered rural settlements by preparing a landslide zoning map. To prepare the zoning map, a combination of effective information layers in landslides including layers of distance from the fault, slope, precipitation, slope direction, lithology, land use, distance from the waterway, height in the GIS environment has been used. Then the weight of layers has been obtained by the ANP method. Finally, the zoning map in 5 classes with very high, high, medium, low, and very low landslide risk potential was prepared based on the rural settlements of the city. Findings show that high-risk areas are consistent with areas without cover or low vegetation, proximity to waterways and faults, and slopes between 20 to 30 degrees. The results also show that about 16% of the area, which is mostly north and northeast. And are in the northwest and are at high risk, which includes 101 villages. Almost all previous landslides have occurred in high-risk and very high areas, which indicates the accuracy of the ANP model in preparing the zoning map. Also, based on the area under the rocking curve (AUC = / 834), the accuracy of the results was confirmed.
