عنوان مقاله [English]
Basically, the establishment and emergence of a city is more than anything subject to environmental conditions and geographic location, since natural features and phenomena have a decisive influence on location, dispersion, penetration area, physical development, urban morphology and the like, and sometimes act as a positive and temporal factor, and in some cases as a negative and deterrent one (Rev. 1382, p. 133).
In recent decades, the city of Karaj has gone through a great deal of physical development due to the increase in population, and the increasing expansion of urban space without regard to geomorphologic processes has caused problems that are studied. In this research, the attempt will be made to analyze briefly the geomorphic phenomena and processes affecting the locating process in the city of Karaj, and to remind the urban planners of the consequences of failure to pay them due attention.
