Geomorphologic and physical growth of the city limits Tuyserkan using geographic information system(GIS)and digital elevation model(DEM)

No one can ever deny the geomorphologic constrains for physical development of cities as a main task of Geographers and urban planners. Recent socio-economic issues caused rapid disproportionate balance of natural potentials of the city by making lots of consequences and risks. Rapid growth of population and occupying more lands in the city lead to misbalancing between physical growth and desirable agricultural farms and gardens around the cities by causing lots of Irreparable damage to the environment. Therefore, locating suitable land for urban development is necessary. In this research, by using questionnaire, AHP model and Fuzzy model in ARC GIS, constrains and preferable lands for future development of Tuyserkan based on 9 criteria (slope, distance from river, distance from the fault, height, coverage vegetation, land type, land use, and flooding of the ground material) were analyzed and mapped to 5 units of zoning.
