Bien que la circulation Nord Atlantique soit relativement bien connue, la trajectoire des masses d’eau au voisinage de la ride de Reykjanes, sud de l’Islande, reste peu documentée. Cependant cette (...)

Sand transport and morphological change occur in the wave bottom boundary layer due to particle interactions with an oscillatory flow and granular interactions between particles. Although these (...)

Dans l’environnement, les courants de gravité sont des processus clés créés lorsque que des différences de densité apparaissent dans le fluide. Ces courants jouent un rôle majeur dans la circulation (...)

Tidal forcing from the Sun and Moon generates 3.7 terawatts (TWs) of mechanical power, of which 3.5 TWs are dissipated in the ocean. It has become understood how energy is transferred into the (...)

Air pollution is currently a very important subject, with the highest levels being encountered during wintertime anticyclonic regimes. This is all the more true in mountaineous regions, where the (...)

The air-sea interaction at the (atmospheric) synoptic and the meso-scale due to momentum transfer, only, is con- sidered. Two superposed one-layer fine-resolution shallow-water models are (...)

The dynamics of unsteady gravity currents propagating up a slope are investigated by laboratory experiments and Large Eddy Simulations (LES), focusing on mixing processes between the dense (...)

Internal waves are of importance mainly because of their capacity to fluid mixing, especially in the deep ocean where motions are generally dominated by these waves. Vertical mixing of water mass (...)

La théorie de la turbulence d’onde est une théorie statistique qui permet de décrire les échanges d’énergie entre des ondes faiblement non linéaires. Initialement développé par Zakharov, elle est (...)
