perron_nlhs.RdSolve nonlinear hillslope evolution using perron2011numerical;textualgeomorphology implicit formulation over one time step
perron_nlhs(z, K, beta, Sc, U, dx, dt)
| z | elevation vector (m) |
|---|---|
| K | hillslope diffusion coefficient (m2/a) |
| beta | rock-to-regolith density ratio (-) |
| Sc | critical hillslope gradient (m/m) |
| U | relative baselevel fall rate (m/a) |
| dx | horizontal distance increment (m) |
| dt | time step (a) |
