Zoning of areas prone to urban development with emphasis on geomorphological limitations and hazards (Case study: Shiraz)

Shiraz, the largest city in the south of the country, is located in the highlands of Shiraz and has had many changes in different periods and continues to increase the urban area that this physical development without geomorphological studies and taking into account the limitations and risks Has been the result. Therefore, identifying areas prone to physical development by considering the limitations and geomorphological hazards is necessary for Shiraz's urban development. The purpose of this study is to identify suitable areas for the physical development of Shiraz city based on the geomorphological conditions of the region. In this study, using the fuzzy model, the final zoning map of urban development was prepared based on six effective parameters. Then, this map was evaluated based on geomorphological conditions and land use of Shiraz plain, and areas prone to urban development were suggested. The past decades have been subject to topographic conditions and there are many geomorphological hazards and limitations in the study area; About 48,000 square kilometers of the area, which is equivalent to 54%, is not suitable for the development of the city. There is a fault and only 17,000 square kilometers, which is equivalent to 19% of the area of the study area is suitable for the development of the city also according to the research results, the optimal location for the development of Shiraz is in the east.
