Séminaire exceptionnel
Résumé : In this talk, the focus will be on kinematic and dynamic properties of dispersive long wave models, such as the Boussinesq and Serre systems. It will be shown how to obtain expressions for momentum and energy densities and fluxes which are given in terms of the principal dependent variables of these systems : the surface excursion and the horizontal velocity. These mechanical quantities can then be used in the analysis of shoaling, wave breaking, and the propagation of undular bores.
