The results of experiments on the influence of a layer of particles of positive buoyancy on the suppression of the breaking process and the regularization of a standing gravity wave on a free surface of water in a rectangular vessel are discussed. The oscillations of a two-layer system in a barotropic mode are considered. Parametric resonance is used to excite the waves in a rectangular vessel. The effect of increase in the upper layer thickness on the limit steepness of the regular wave and its dissipative properties are considered. It is shown that the use of floating polystyrene particles as the upper layer changes significantly wave mode dynamics, namely, regularization of waves with complete suppression of breaking mechanisms.
