WebSince inflection points in slope–area space are thought to indicate changes in process between diffusive hillslope processes and advective fluvial processes at a saturation threshold (Tucker and Bras, 1998; Clubb et al., 2016), these failures probably represent hillslope positions that failed at saturation when throughflow was high. WebChapter structure. Hillslopes are an almost universal landform, occupying some 90% of the land surface. In hilly and mountainous regions, long-term downslope movement of soil on hillslopes can play a crucial role governing the rate at which landscape evolves through time.
