Soil Erosion by Water/Sediment Continuity

← previous

Sediment ContinuityEdit

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

steady state sediment continuity equation (Nearing et al., 1989)[1]:


whereby interrill erosion  is considered to be independent of  . Rill erosion  is positive for detachment (eqn 1.26, cf. section → Rill Erosion) and negative for deposition (eqn 1.28).
