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

Abstract

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