Abstract

EROSION is a process during which soil particles are separated from their beds, and they are moved and deposited with the help of a conveyor factor to another place. Sedimentation and EROSION are major concerns in most regions of Iran, and estimating the scale of EROSION and sedimentation is very significant.Determining the amount of EROSION in drainage basin is practiced in various ways among which we can point out EROSION studies methods such as, PSICAC, EPM and GIS. In this research, USLE method has been applied to assess the ratio of EROSION of almost unconsolidated pre-quaternary and quaternary formation to EROSION in DAMAVAND DRAINAGE BASIN. For this purpose, 18 samples of UNCONSOLIDATED DEPOSITS of DAMAVAND DRAINAGE BASIN were taken and then by applying the effective factors in Universal Soil Loss Equation, the rate of soil loss of such deposits has been measured. The results showed that the soil loss is mostly found in the lower red formation and the highest amount of EROSION is discovered in Hezar-Dar’reh formation. Since Hezar-Dar’reh, lower red and upper red formations are near the main water channel, the basin’s outgo and the dam which is under construction in Malmo, an operation of sediment and drainage control should be carried out to prevent EROSION and sedimentation.
