Soil Erosion by Water/Sediment Continuity

Sediment Continuity

Overall net erosion along a hillslope as function of downslope distance $x$ may be calculated by solving a

steady state sediment continuity equation (Nearing et al., 1989):

$\frac{dG}{dx}=D_{f,r}+D_{f,i}$   (1.31)

whereby interrill erosion $D_{f,i}$is considered to be independent of $x$. Rill erosion $D_{f,r}$is positive for detachment (eqn 1.26, cf. section → Rill Erosion) and negative for deposition (eqn 1.28).
