Evaluation of geo - morphological effect on urban development in sanandaj city

Most cities in our country Iran has been located on compactable frames caused by water flow from gorges and deltas. There have been a number of significant investigations on potential geo morphological factors which are considered as a threat to the integrity of our cities however villages and countryside locations and their glaciers have never been a matter of such attention. In Iran civil centers have great similarities in common however differ significantly in terms of artistic entity. Rural civil centers follow Quarter sequence. It primarily follows balance of water and ice then elongates to precipitate surfaces. Topographical maps of the city of Sanandaj reveal the fact that this area in turn follows these characteristics and indicates that this city has never been a focal point of civil growth. Ethnical alteration has also been a factor in this regard. Area under investigation was designated after evaluation of topographical maps of Geo. In this work GIS software was employed for analyzing cooperative effect of internal and external centers and isothermal rates of past and present obtained for city of Sanandaj and snow lines was evaluated then through right program. In the latter stage Surfer software was employed and cooperates of adiabatic. At the end all maps were overlade and topographical map was obtained for snow line and rural area disparity. Glacier summits were as high as 2000 and these change in rout has significant effects which in turn shows frigidity in fourth period. Shape of graphical illustration indicates high synovial shape which indicates the exertion of fridge in the region. Theses surfaces are formed primarily due to the movements of ice lines along with mountainous fridge summit. Pinpointing snow line through utilization of Right procedure shows that yearly temperature is of significant in 2000 meter height. Designation of different circus of 99 small and big sizes indicates that circuses played a significant role in construction of fridge line in the region. Distribution of rural areas in city of Sanandaj follows the exact fridge summits proves the overall identity of fridge summits.
