The fluid motion in a cylindrical tank is considered under the influence of constant horizontal disturbing force. Researches have been done with taking into account the forced oscillations of the free surface at the period of the fluid first burst. The results of obtained numerically-parametric investigations allow us to construct the free surface profiles and determine the boundary of transition in perturbed states.
