Calculated factors such as level, shape, slope, drainage network and calculated and delineate curves hypsometric and curves undimension hypsometric constructed after analysis erosion and sedimentation in Watershed Ladiz have been done. Physiographical properties subwatershed in Geographical Information System (GIS) environment is obtained indicating equilibrium between the mountains and plains of the Saadabad subwatershed. Mianrud and Siahjangal subwatershed and young areas and their heights is highly exposed to erosion. Comparison of the extent, shape, slope and curves hypsometric subwatershed indicate the extent and severity of erosion under the mianrud area than other areas under more. General watershed areas Ladiz young and active can be considered as more than 3/2 level of the mountains is at risk of erosion and shall not establish the equilibrium.
