The shear resulting from internal wave reflections can play a crucial role in the transport and resuspension of sediments oceanic conditions. In particular, when these waves undergo critical reflection phenomenon, reflected produce very large shear. Separating incident is technical challenge since two share same temporal frequency. our study, we present series experimental measurements configur...

A flow that arises in a turbulent wake behind a body that moves in a stratified fluid is rather peculiar. With a relatively weak stratification a turbulent wake first develops essentially in the same way as in a homogeneous fluid and extends symmetrically. However, buoyancy forces oppose vertical turbulent diffusion. Therefore a wake has flattened form at large distances from the body and, fina...

Stratified flow over topography is studied, with oceanic applications in mind. We develop a model for a fluid with arbitrary vertical stratification and a free surface, flowing over threedimensional topography of arbitrary size and steepness, with background rotation, in the linear hydrostatic regime. The model uses an expansion of the flow fields in terms of a set of basis functions which effi...
