hillslope_transport_nonlinear

Hillslope mobile-material discharge per unit width following a nonlinear transport rule (Roering et al., 1999)

$$ \bar{q}_s = \frac{D \nabla z}{1 - \left( |\nabla z| / S_c \right)^2} $$

• $\bar{q}_s$: Mobile material discharge per unit width [m² / s]
• $D$: Hillslope diffusivitity [m² / s]
• $S_c$: Critical slope [–]
