Abstract: The population growth has accelerated the physical expansion of cities and increased the risk of geomorphology in urban areas. Considering the importance of hazards and its association with casualty and financial damages, this study evaluates the hazards facing the urban area of Qorveh and Qaleh discontinuous urban area. Since the purpose of this study is to identify the geomorphological hazards of Qorveh city, firstly using different information layers and library information and field observations, the general status of the area has been evaluated and three types of risk of slope movements, flood and subsidence have been identified for the region. Then, using fuzzy logic, radar images, and SBAS method, as well as field observations, the susceptible areas of slope movement, subsidence, and flood were identified, respectively. The results indicate that the study area, especially the southern margin of Qorveh and the margins of the Qaleh River, with a maximum of 47 mm subsidence, has a high potential for subsidence. Also, due to the status of the Qaleh River, the marginal areas of this river that have been the focus of many settlements in recent years have great potential for flooding, as well as parts of the western area of Qorveh which advance towards the slopes of Mount Kolava, are subject to slope movements.
