Description :
The aim of this study was to identify parcels which are severely affected by water erosion and to identify areas at risk for sediment input to surface waters. For this purpose, the ABAG, an adaption of the USLE approach to German conditions, has been employed with the best available data sets on K-, C-, R- and LS-factors. Model results show that soil losses in Hesse vary between 0.5 and 15 tonnes/(ha.year). The mean loss amounts and the sediment delivery ratios for sub-catchments are also evaluated. Uncertainty analyses reveal an overall error of 34 % of the model results and outline the contribution of each input data set. The findings from this study are used for policy support in the field of soil and water resources management.
