The article describes the results of laboratory experiments devoted to the estimation of bottom topography influence on the stationary surface waves’ frequencies and forms in a rectangular vessel which oscillates in vertical direction. The effect of one or two elevations at a horizontal bottom and at a linear shoal is considered properly. The resonance deviation with respect to the obstruction position changing is investigated in the experiment at a linear inclined bottom. The mathematical model of seiches based on the accelerated convergence was used to explain the results of experiment in case of abrupt elevation.
