Hillslope position
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. WebDec 1, 2024 · One-way analysis of variance (ANOVA) was conducted to assess the differences in the physical properties between the various soil layers and the different hillslope positions (Lix et al., 1996). ANOVA was also performed to determine the effect of different hillslope positions on the infiltration capacity, preferential flow indices, and root …

WebA catena in soil science ( pedology) is a series of distinct but co-evolving soils arrayed down a slope. [1] Each soil type or "facet" differs somewhat from its neighbours, but all occur in the same climate and on the same underlying parent material. A mature catena is in equilibrium as the processes of deposition and erosion are in balance.
