Abstract:
Erosion is process in which soil particles are separated from their bed and moved to another location with the help of transferor and deposited there. Today, erosion and sediment are of the major problems of different catchment basins in Iran and determining their extent is of the upmost importance. Empirical model of erosion has been developed for a specific area and it is necessary to calibrate it to use in the conditions except the place where it was provided. This study aimed to estimate the erosion and sediment of Shahzadeh Abbas catchment basin in Kerman Province. For this purpose, the hydrological model HEC-HMS (V.4) was used and the efficiency of Universal Soil Loss Equation (USLE) and Modified Universal Soil Loss Equation (MUSLE) was evaluated in the mentioned area. Finally, the results show that Modified Universal Soil Loss Equation (MUSLE) technique has good agreement to the observed data and reaches the overlap of 85%.
