Numerical scheme for a stratigraphic model with erosion constraint and nonlinear gravity flux
Résumé
In this work, we study an extension of the model introduced by Eymard et al. [Int. J. Numer. Methods Engrg. 60, 527–248 (2004)] for the simulation of large scale transport processes of sediments, subject to an erosion constraint. The novelty we consider lies in the diffusion law relating the flux of sediments and the slope of the topography, that now involves a p-Laplacian with p > 2 in order to get more realistic landscape evolutions. This physical sophistication entails the construction of an entirely new numerical scheme, the details of which shall be supplied.
