Waves in the coastal environment are one of the major sediment transport factor. It has been shown that sea grass play an important role in their attenuation, but it is currently difficult to (...)

L’Antarctique est une calotte de glace dont l’ épaisseur dépasse par endroit les 3000 mètres. Cette calotte est recouverte d’une surface de neige, souvent plus froide que l’air : on appelle ce (...)

A minimal two-phase model to study turbulent bedload transport focusing on the granular phase is presented and compared with experiments. The model intends to describe bedload of massive (...)

Nowadays measurements of flow velocities of incoming waves on beaches exist mostly of using acoustic instruments. These methods are limited when the sediment concentration becomes large, or for (...)

We consider experimentally the mechanisms of mixing in stably stratified Taylor-Couette (TC) flow in a TC apparatus for which both cylinders can rotate independently. In the case for which only (...)

Experimental results using a PIV measurement technique of gravity currents over concave slopes with different initial slope angles are presented. For large angles, the flow follows a periodic (...)

Wall convection produced by hot walls is of great interest to many industrial and environmental applications. In this experimental-theoretical investigation we consider a turbulent plume (...)

The organization of experimental data is a recurring problem, especially on a large installation such as the Coriolis platform where data from multiple cameras and instruments are used by a group of researchers and must remain accessible several years after the experiments. The tool uvmat under Matlab provides processing programs likes PIV but it more generally proposes a systematic data organisation using the standard binary format netcdf and documenting the processing parameters by xml files. Furthermorte it gives access to the computer cluster in a way transparent for the user.
