During this presentation\, we first present models able to approximate the hydrostatic Navier-Stokes equations. The associated numerical schemes are endowed with stability properties such as positivity\, well-balancing and discrete entropy inequality. They are confronted with analytical solutions and experimental measurements. Then we propose non-hydrostatic (dispersive) models and numerical procedures to approximate them. But the numerical analysis of such models is complex and several questions remain opened. \nEDP : Jacques Sainte-Marie (INRIA Paris) : Geophysical flows : from hydrostatic to non-hydrostatic models URL:https://lmv.math.cnrs.fr/evenenement/jacques-sainte-marie-inria-paris/ LOCATION:Bâtiment Sophie Germain\, salle G210 CATEGORIES:Séminaire EDP END:VEVENT END:VCALENDAR
