Assimilation de données pour les modèles d'hydraulique fluviale. Estimation de paramètres, analyse de sensibilité et décomposition

Abstract : Flood prediction requires to use every available information. Mathematical equations which allows to build a model, satellite images describing the domain and in situ measurement. Those observations are necessary to make a good prediction because they are the witness of the terrain reality. The aim of this work is to present and test some methods based on the control theory which allows to use optimally every available informations. Some applications of these methods will be treated as parameters estimation, sensitivity analysis and coupling models.
