ملخص المقالة :
In order to analyze the erosion and sedimentation areas of the Ladiz drainage basin, factors such as level, shape, slope, drainage network and constructed hypsometric and undimensional hypsometric curves have been taken into account. Physiographical properties of subordinate drainage basins obtained from Geographical Information System (GIS) indicate that the extent of mountains and plains of the Saadabad drainage basin are in equilibrium. The Mianrud and Siahjangal subordinate drainage basins are in an elevated youth stage, therefore highly exposed to erosion. Comparison of the extent, shape, slope and hypsometric curves of subordinate drainage basins indicate a greater extent and more severe erosion of the Mianrud area than of others.
