The stability of the plane free surface of water in a vertical vibrated vessel with corrugated bottom.
In this paper, an experiment was conducted to study the vibration of the shallow water in a vessel with corrugated bottom. When the bottom of the vessel is cosinoidal, the conditions of excitation of the surface waves are modified especially vastly, which has been elucidated in detail by Osipov and Garcia [V.V. Osipov, N. Garcia, Phys. Lett. A 283 (2001) 209-215]. The experiments serve to illustrate the effects under discussion and show the vivid phenomenon of localization near the band gaps. Finally we compare the results of the experiment with the theory and discover two special phenomena, which have not been revealed in theoretical computation.
