Use of Chosen Methods for Determination of the USLE Soil Erodibility Factor on the Example of Loess Slope

anglais. The investigations were carried out on a loess slope in the Brzeźnica village, in the Rudnik commune. Nine points were chosen, in which particular parameters being parts of the examined models, were determined. On the basis of the literature, eight models for the Universal Soil Loss Equation (USLE) erodibility factor determination were designated. The chosen models were the ones proposed by: Wishmeier, Monchareonm, Torii et al. and Walker (all based on texture and organic matter content, Wischmeier and Smith (based on texture organic matter content and additionally on aggregate classes), Wiliams et al. (based on texture and organic carbon content), Renard et al. as well as Stone and Hilborn (both based only on texture). The investigated site was characterized as well. The statistical conclusions were drawn and the obtained results were compared with the results presented in the literature.
