摘要：Soil water erosion represents main wide spread physical degradation process on soils in conditions of Slovakia. This process causes gradual decrease of soil productivity and its ability to infiltrate and store the water, nutrition, organic matter, and soil biota with resulting transformation of soil profile. The soils affected by soil erosion cover approx. 2/3rd of the territory of Slovakia, characterized by undulating topography. Most affected are hilly lands with typical loess soils with intensive agriculture. In case such region is the subject of realization of land arrangement projects, these projects should include the complex proposal for minimalisation of the effect of soil erosion. The complex evaluation of soil erosion risk include the modeling of soil erosion, interpretation of results, validation and proposal for mitigation of soil erosion. Erosion prediction has been most widely used as a tool to guide conservation planning and for this purpose many empirical and mathematical models have been developed. The long-term soil loss predicted by models is often hardly visible in the landscape. Thus various field techniques must be used to evaluate and validate modelling results otherwise model predictions are hardly accepted by agricultural practitioners. These techniques require the evaluation of characteristics of eroded soils, identification, measurement and calculation of erosion gullies, altitude changes of soil surface etc.
