Evolutionary studies of the Vazneh and Baneh basins by using dimensionless hypsometric curves

The physical attributes of Basins have great effects on the process of erosion. Among the most important parameters of basins that directly or indirectly have great effects on the erosion. For example the elevation of basin indicates its climatic condition and it is effective in raining and considering the face that each rainfall has its own hydrology it has special role in erosion. Therefore in order to analyze the condition of erosion and sedimentation with a comparative view in the basins of Vazne and Bane, undimensional hepsometric tables and curves have been designed.It becomes clear that in the Vazne basin the development of plain and elevation is tosome extent balanced. The low space between two curves is indicative of the approachof the basin to equilibrium. in contrast in Bane basin considering the condition of the curves it becomes clear that tis Basin is more away from that equilibrium and is younger and less development.
