The purpose of this study is to analyze the environmental risks of soil erosion in the runoff of the Shahid Rajaei Dam in Sari based on GIS and remote sensing approach. In this study, soil erodibility was assessed based on the global model of soil loss called RUSLE with rainfall erosion input parameters, soil erodibility, topographic factors: length and slope, land cover management, conservation operations. For this purpose, before producing the results of these factors, first the input data such as DEM, slope, geological layer, land use layer, precipitation, soil, vegetation index was prepared and their spatial distribution pattern in the study area was described and analyzed. In the next step, the potential for flooding and runoff production was measured using the criteria of distance from waterways, drainage density, slope, slope direction, land use, rainfall, geology, soil type. In this regard, while fuzzy the layers, different variables were applied in order to integrate the mentioned layers in the final step on the production of flood potential map and runoff production. After producing the main layers, namely flood potential and runoff production, soil erodibility was studied using Pearson correlation test and regression model of the relationship between these factors and the results were discussed. The results of this study showed that remote sensing and GIS techniques in combination with field measurement values of the studied parameters can have many applications in the field of environmental studies in the field of civil engineering and in modeling and estimating environmental parameters.
