Description	The EROSION 3D model was applied in the Svacenicky creek catchment (6.3 km2) in the middle of the Myjava Hill Land in Slovakia. The results show the variable influence of each soil parameter. The EROSION 3D model is very sensitive to initial moisture, bulk density and skin factor. Lower affect is caused by organic matter content, and some of the soil parameters had “no influence” on the particular modelled values, respectively runoff-erosion processes. The diversity of the results pointed to complexity of the EROSION 3D model and the complicated assessment of runoff-erosion processes. The strong relationship between the “input” soil parameters and “output” modelled values was also confirmed, which outlines the necessity of correct determination of all input parameters.
