Abstract: Surface waves instability has been experimentally studied in a cylindrical basin subjected to a horizontal oscillation. We show that the presence of two modes, respectively parallel and perpendicular to the direction of the forcing, may produce either a stable or a time-dependent superposition of the two modes. The phase diagram of the system, the surface deformation amplitude and the features of the time-dependent regimes are in satisfactory agreement with the available theoretical predictions.
