Abstract: The conditions at which buoyant blocks on a stream become unstable and are swept under the downstream floating cover are investigated analytically and experimentally. The theoretical model is based on a one-directional analysis of the flow passing under the floating cover and moment equilibrium of the floe. Laboratory experiments to verify the analysis were conducted in a flume using individual blocks with three different specific gravities and ranges of length and thickness. Values for the moment coefficient arising in the analysis were determined from the laboratory data. Satisfactory agreement was found between the analytical model and laboratory and field data.
