Interaction houle-courant en bathymétrie variable via une approche de type boussinesq 5
Guinot, Florent; Le Boulluec, Marc; Rey, Vincent.
Modeling wave-current interaction needs a method combining accurate kinematics and reasonable computing efforts. Refined waves kinematics are described by a Boussinesq-type approach allowing a variable bathymetry. This method is adapted to take current effects into account. Results on Doppler shift, waves blocking and velocity profile are reported in a twodimensional case.

Interaction houle-courant par profondeur finie : impact sur la cinématqiue 5
Rey, Vincent; Guinot, Florent; Le Boulluec, Marc.
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.
