Natural factors have a great impact on location selection, development, physical development and morphology of cities. Sometimes these factors create crisis in the physical development of a city. The main goal of this research with this point of view is the pathology of physical development crisis of Sanandaj. Therefore, to achieve this goal various types of topographical and geological maps, land use maps, weather data, library and field research have been used. For this reason research on the scope of region to be studied was determined on topographic geological maps, then making digital maps, error correction, and preparing topology were done and database of maps and needed output were extracted. After this part, field studies took place. The results showed that factors such as altitudes of Abidar, Hills within the city, Gheshlagh river, have created some problems in developing the city, so that about 5 percent of the studied area is appropriate for development of the city that must be managed properly.
