Abstract:
This paper describes the technique and results of an experimental study of the longitudinal force component, the vertical coordinate of its application point, and the overturning moment for the impact of a bore on a vertical plate. The bore was generated by removal of a shield which produced the initial free-surface level difference in the channel (in the model formulation of the dam-break problem). It is shown that the greatest forces and overturning moments occur at the ratio of the initial headwater and tailwater levels at which a bore with a developed head roller is formed.
