Abstract

Soil erosion is considered as one of the most common forms of degradation, and as such affects the environment. Nowadays there are various methods to assess the loss of soil due to erosion and represent an alternative means by which it is possible to estimate the amount of soil loss in the given area. In this paper Erosion Potential Method (EPM) is used by applying GIS in the territory of the municipality Beocin. The preliminary parameters in the form of raster maps have been previously prepared: the digital elevation model, the pedological and geological map, the Corine Land Cover, as well as the results of previous pedological studies in order to determine the soil erodibility factor. In the investigated area processes from first to the fifth category of erosion were observed. The degree of threat to erosion processes is in proportion to the extent and type of activity in the investigated area, which was expected due to the high inclination of the terrain and unstable geological substrate. The Erosion Potential Method proved to be suitable for defining erosion processes in the investigated area, although the input parameters were insufficient.

Highlights

Erosion is considered to be a natural phenomenon that leads to the displacement of parts of soil and rock due to water, wind, ice and gravity
The degree of erosion is mainly determined by physical factors, for example, soil characteristics, the formation of rocks, topography and the amount of soil material that is available for transfer, which usually is proportional to the erosion ability of soil and land use (Amiri, 2010)
With a view to assess the intensity of soil erosion and to propose measures for reducing the degradation process, developed many methods for assessing erosion loss of land

Summary

Introduction

Erosion is considered to be a natural phenomenon that leads to the displacement of parts of soil and rock due to water, wind, ice and gravity. The method takes into consideration surface geology and soil properties, topographic features, land use type and distribution and the catchment’s degree of erosion.
