Dear Ronni . With regard to your question , there has been lot of developments . Different modelling approaches (PESERA, MESALES, G2, USLE)  have been widely discussed. Moreover, data for the K-Factor (Soil Erodibility), R-factor (Rainfall erosivity), LS-factor (Slope Length and Steepness), P-factor (Support practices) in European level are available. At the end, the assessment of soil erosion in the Alps is presented as well on the European portal.   

Hi

In the case of wind erosion there is no easy way of accounting for the total soil loss.

Usually black storm...

Тhe number of blown soil in some cases reaches a very large size — 120000 to 124000 kg/ha.
