An experimental procedure for studying soliton gases in shallow water is devised. Nonlinear waves propagate at constant depth in a 34\,m-long wave flume. At one end of the flume, the waves are generated by a piston-type wave-maker. The opposite end is a vertical wall. Wave interactions are recorded with a video system using seven side-looking camer...

La turbulence d'onde est un état statistique impliquant un grand nombre d'ondes couplées par effet non linéaire. Cet état générique est potentiellement décrit, dans la limite de faible non linéarité, par la théorie de la turbulence faible. Cette théorie prédit un phénoménologie proche de celle de la turbulence hydrodynamique avec en particulier une...
The nonlinear dynamics of waves at the sea surface is believed to be ruled by the weak-turbulence framework. In order to investigate the nonlinear coupling among gravity surface waves, we developed an experiment in the Coriolis facility, which is a 13-m-diam circular tank. An isotropic and statistically stationary wave turbulence of average steepne...

We report on an experimental realization of a bidirectional soliton gas in a 34-m-long wave flume in a shallow water regime. We take advantage of the fission of a sinusoidal wave to continuously inject solitons that propagate along the tank, back and forth. Despite the unavoidable damping, solitons retain their profile adiabatically, while decaying...
We investigate experimentally turbulence of surface gravity waves in the Coriolis facility in Grenoble by using both high sensitivity local probes and a time and space resolved stereoscopic reconstruction of the water surface. We show that the water deformation is made of the superposition of weakly nonlinear waves following the linear dispersion r...

We discuss the impact of dissipation on the development of the energy spectrum in wave turbulence of gravity surface waves with emphasis on the effect of surface contamination. We performed experiments in the Coriolis facility which is a 13-m diameter wave tank. We took care of cleaning surface contamination as well as possible considering that the...
