Soil erosion is considered a serious threat to the pollution of water sources, soil wastage and the spread of environmental pollution in arid and semi-arid areas. The purpose of this study is to evaluate the erosion rate in the watershed of the tailing dam of Dar-e-Allo copper mine and calculate the amount of annual sediment input behind the dam. The results of the field study and laboratory data show that based on the MPSIAC model parameters, the watershed of the waste dam of Dar-e-Allo mine is in the category of basins with low erosion. Among the nine effective factors in soil erosion, river erosion is known as the most effective factor in the whole watershed and the western sub-basin. The topographic factor has the greatest effect in increasing the transported sediment load, in the eastern sub-basin. On the other hand, the land cover factor shows the minimum effect on the production of sediment in the catchment basin. This shows that human activities in this watershed do not have much effect on the surface soil degradation. On the other hand, the EPM model evaluated the severity of erosion in the study area as severe to very severe due to the ignoring of many effective parameters. The evaluated values are highly exaggerated and far from reality by considering the natural conditions prevailing in the area. Therefore, the MPSIAC model is highly recommended for erosion studies in the upstream watershed of the tailings dam of Dar-e-Allo Cu despite being expensive and time-consuming.
