Use of the USLE 2D Model to Assess the Impact of Anti-Erosion Measures on the Extent of Potential Water Erosion in the Research Area of Sobotište

Abstract

The article focuses on assessing the impact of anti-erosion measures on soil water erosion implemented at the Sobotište research site, covering an area of 68 ha. The anti-erosion measures consist of two water retention grass ditches located in the lower part of a slope and a change in the management of the entire slope. The assessment twas conducted by comparing slope conditions before and after implementing anti-erosion measures using the Universal Soil Loss Equation (USLE) and the USLE2D sub-model, which calculates the LS topographic factor. The modelling was conducted in the ArcMap software environment with a digital relief model resolution of 1 × 1m and the LS topographic factor calculation algorithm according to the author McCool [1].
