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.
