Interaction houle-courant par profondeur finie : impact sur la cinématqiue

The aim of this large scale basin experiment on wave current interactions was a better understanding of vertical velocity profiles changes due to progressive surface waves. The instrumentation deployed including wave gauges, pressure sensors and current meters allowed precise measurements along the basin. In particular, the effect of waves on the homogenization of vertical profile was measured, and the effect of current on the underestimate of wave height from bottom mounted pressure sensors was demonstrated. However, the current flow without wave was bi-dimensional and weakly sheared, and no study on the current instability as observed in previous experiment could be achieved.
