Application of USLE, GIS, and Remote Sensing in the Assessment of Soil Erosion Rates in Southeastern Serbia

Polish Journal of Environmental Studies

The assessment of soil erosion rate and its spatial distribution in the hilly-mountainous Nisava River basin was conducted by Universal Soil Loss Equation (USLE) model through a GIS-based approach. A Landsat 7 Enhanced Thematic Mapper (ETM+) image and normalized difference vegetation index (NDVI) were used for the determination of crop management factor. The average annual soil loss was estimated at 13.1 t·ha-1·yr-1, classifying the Nisava River basin under the high erosion rate category. Abou
