We investigate experimentally and numerically arising of modulations of nonlinear shallow water waves in a resonator with a periodic external excitation.Experiments were carried out in a hydrodynamical channel.The length of the channel was L=17m, its width was d=0,5 m, and the depth of the liquid layer was h=0,17m.A piston type wavemaker consisting of a vertical plate set in motion by DC engine excited waves with frequencies 0,34 Hz < F<0,48 Hz (parameter 0,28 < kh < 0,42, k is for wave number).
