Abstract

Recent research has indicated the large spatial and temporal variation in soil erosion resistance against concentrated flow (SER). This study analyzes this variability in relation to rill and gully initiation locations on slopes and the downslope eroded volumes in the Belgian loess belt (Ganspoel catchment). Therefore, concentrated flow paths and topsoil properties were measured in their vicinity. Soil conservation measures affecting one of the soil properties that control soil erodibility (e.g. double drilling of the thalweg, conservation tillage) can decrease the cross-sections of the concentrated flow paths. These findings also indicate that rill and gully initiation points are not only topographically controlled but also depend on the SER, which in turn determines the dimensions of these concentrated flow paths. Hence, knowledge of the variability in SER is indispensable
