vegetation covers are common. A simulation approach was used to test the hypothesis that hillslope discharge and soil loss could be affected by variation in the spatial correlation structure of coupled vegetation cover and soil patterns alone. The Limburg
This study was conducted in a wind tunnel rainfall simulator facility at Ghent University, Belgium. The AA present experimental results directly obtained on the effect of horizontal wind velocity on sand detachment from splash cups

with sparse vegetation cover. This paper reviews the recent findings in this area obtained from field evidence and numerical simulation experiments, and outlines their implications for soil erosion assessment. VDSH is often observed at 2 scales, individual
and analysed. Although the net erosion rate in the catchment is relatively low, the described event with soil frost is considerably different from the event without soil frost. A model approach, WaSim, to simulate the runoff generation in the catchment during
