Geomorphologic Possibilities & Limitations Analysis in Selecting Urban Development Directions (Case Study: Darab)

The aim of this study is to understand the phenomena and geomorphologic processes affecting the urban development, and also the abilities and limitations of such factors. Darab city was selected as case study due to the existence of geomorphologic limitations in the cityʹs different sides. Darab is located in the south eastern of Fars province. The research focuses on identifying the abilities and geomorphologic limitations available in different directions of the city by documentary investigation, map and remotely sensed data investigations and field observations, and finally determining the best aspect for development in the of the city future. The results showed that Darab faces geomorphologic limitations in all sides; limitation of runoff accumulation and underground water excavation because of low aquifers slope in the south, desirable agricultural lands and soft soil in the west and southwestern parts, elevations and scope processes in the north and northeastern parts, and young and unstable piedmonts in the east and southeastern sides. Therefore, Darab city will encounter geomorphologic limitations in the future development, especially in the geomorphic processes related to the runoff and underground waters. Consideing that the cityʹs development needs and serious limitations in other directions, the most proper direction for Darab expansion is the lands located in the eastern part of the city, respectively.
