Abstract

North Eastern hillside of Karkas Mountain is located in South Western region of Natanz County with a North West-South East direction. The area is located in 51° 30´ to 52° 4´ Eastern longitude and 33° 26´ to 33°         48 ´ Northern latitude. The lowest altitude is about 970 meter which goes up to 3895 meter in Karkas arête. Study area borders with two basins named Natanz (Ure, Tame) and hanjan (Barzrud, Chime Rud), both of which are located in Ardestan basin.
Two major geomorphologic units of the area includes:
-High elevations of Karkas which are mainly more than 3000 meters high.
-A low area with 970 meters in the lowest points which is a part of subsided strip of Qom-Ardakan.
Geological structure, climatic diversity, lithological features, current topography and hydrology of the area and active morphodynamic factors have resulted in significant diversity of geomorphologic phenomena in North Eastern hillside of Karkas Mountain. So that glacial morphogenesis system dominates the higher elevations of Karkas Mountains while arid, erosive systems dominates the desert (Badrud Desert).
