Numerical estimation of phenomenological parameters for sand dune formation by solving an inverve problem

摘要

We are interested in this work to a numerical estimation of parameters?intervening in the formation process of the sand dunes. They are in?particular the phenomenological parameters and which influences respectively?the curvature and the slope. We formulate an optimal control?problem (inverse problem) and we implement several numerical methods?to approach the problem. Then we make a comparative study of?these numerical methods in order to choose the best for the analysis.
