    Soil erosion is one of the environmental hazards. The aim of this study was to predict water erosion and evaluate it with CORINE and ICONA models in the study area of ​​Talesh city. In CORINE model, parameters such as topography, erodibility, erosion and land use and vegetation are required, and in ICONA model, slope, geology, land use, vegetation are required. The results showed that the highest area in the erosion risk map of 2000 is the CORINE model of the middle erosion class with an area of ​​63.22%. In 2020, the highest area is related to high erosion class with an area of ​​45.67%. These areas are seen in the western, eastern and central parts of the range. The results of the ICONA model for the period 2000 to 2020 showed that the high and very high risk classes in 2000 were 8.01 and 2.31 percent, respectively, while in 2020 these figures reached 8.80 and 3.44 percent. The results of the evaluation of the final zoning of the erosion risk map of the area, the study area with terrestrial realities, showed that in the best case, the overall image zoning accuracy of 2000 and Landsat 8 of 2020 CORINE model are equal to 0.87 and 0.91 and kappa coefficient of 0.86 and 0.89, respectively. It was estimated to be acceptable. In the ICONA model, the kappa coefficient and overall accuracy of 2000 were 0.85 and 0.86, and for 2020, 0.87 and 0.88, which were acceptable. Manuscript profile
