The effects of incorporated residue on rill erosion include: (1) reduced shear stress on the soil as residue becomes exposed, (2) increased channel stability as residue elements acting as miniature grade control structures reduce the channel grade, (3) decreased channel scouring as the residue halts rill headcut advance, and (4) increased scour hole erosion as runoff moves over the residue elements.
As the residue is exposed the total shear stress is divided between the stress acting on the soil and on the residue. Rill grade stability when the residue acts as a miniature grade control structure. This effect reduces the rill slope and the erosive potential of the flow. Reduction in scouring when the residue halts headcut advance. Scour hole erosion when the residue creates a plunge pool. When the residue creates a stable overfall, a scour hole may form and increase soil loss.
