    Abstract

    There has been an increasing interest by decision makers to obtain regional assessments of soil erosion risk, whereas many existing models require substantial amounts of high quality input data with high spatial resolution and they are often only validated at the plot level. Operational models for regional assessments should be based on simple data requirements, must consider spatial and temporal variability in hydrological and soil erosion processes, and must be applicable to a variety of regions with a minimum of calibration. This study aims to assess the applicability of the Erosion3D model for erosion risk assessments at the landscape scale in Slovakia using a combination of quantitative and qualitative methods for assessing spatial prediction patterns. The model was set up for the Paríž catchment (239.93 km2) in south-western Slovakia. The area has been intensively cultivated primarily with cereals, sunflowers and corn and is characterised by poor cultivation practices and use of fertilizers leading to land degradation. As a first step, the initial raster-based modelling of soil loss and deposition has provided acceptable and realistic values. The predicted spatial patterns of erosion are now being identified using farmer participation to ensure that the ‘correct’ hot spot areas are being identified. In the end, scenarios will be set up to assess the effect of farming practices and/or conservation measures on soil erosion rates in the area.
