Ratio of the nonlinear to linear components of the sediment flux

Compute ratio of the nonlinear to linear components of sediment flux at the base of the hillslope according to roering2001hillslope;textualgeomorphology

hillslope_psi(U, K, L, beta, Sc)

Arguments

U

relative baselevel fall rate (m/a)
K

hillslope diffusion coefficient (m2/a)
L

hillslope length (m)
beta

rock-to-regolith density ratio (-)
Sc

critical hillslope gradient (m/m)

Value

Value of Psi, which can be a vector
