Abstract

The AA. proposed a semi-empirical model approach that relates the potential detachment rate by means of a bi-linear combination to the attacking forces of rainfall (characterised as momentum flux of rainfall) and overland flow (characterised as shear stress). Secondly, data from 58 rainfall simulation experiments performed in the Weiherbach catchment (Southwest Germany) were used to parameterise the erosion resistance under field conditions. They found evidence that cultivation was the first order control of the erosion resistance on conventionally tilled loess soils. For bare soils they found a strong correlation between the erosion resistance, surface roughness and clay content. These results can be used to predict the erosion resistance and regionalise it to the catchment scale as input parameter in a soil erosion mode
