THE BEHAVIOR OF AN INCLINED PONTOON BREAKWATER IN WATER WAVES

The inclined pontoon breakwater, or sloping float breakwater, is a row of bargelike pontoons moored so that, at rest, the shoreward ends, which are ballasted, rest on the seafloor while the seaward ends, which are buoyant, project slightly above the water surface. The development of a prediction technique for wave attenuation, motion, and mooring forces was initiated with the formulation of an analytical model. Experiments in a wave tank with a hinged plate were conducted, and the results confirm certain elements of the mathematical model. Data on wave transmission and mooring forces were obtained from initial experiments with a model barge (pontoon). (Author)
