Abstract
P001 DEVELOPMENT AND APPLICATION OF A MULTI-LITHOLOGY STRATIGRAPHIC MODEL UNDER MAXIMUM EROSION RATE Abstract 1 We consider here a stratigraphic model coupling a multi-lithology diffusive model with a constraint on the erosion rate. A finite volume implicit in time discretization is derived from this model leading to a non-linear system which is solved using a Newton algorithm adapted to the constraint. However this method can lack robustness especially for small mesh sizes. In this paper we present a simulation of this model on real input data and some techniques to improve the convergence of the Newton method. Finally we will
