Abstract

Water erosion has become a serious problem at global level. In the conditions of Slovakia, soil erosion processes can be found predominantly in lowland hill land, which have suitable climatic and soil conditions for intense agricultural use. The research of water erosion was carried out in the lowland type of hilly landscape. The aim was to monitor and evaluate the importance of selected factors (slope, slope length, exposure) for the development of water erosion. The first step was to identify erosion. In the research of soil erosion in the model area, the method of identifying the spatial spread of erosion areas. The evaluation was based on analyzes of individual factors and identified areas actually threatened by water erosion. The decisive primary factor for erosion processes is the slope and slope length.

Keywords: identification of erosion, erosion factor, slope, slope length, exposure, lowland type of hilly landscape
