The use of perforated pile beakwaters to attenuate waves

A laboratory investigation was conducted to compare the transmission characteristics of one-row and two-row submerged perforated pile breakwater models. The laboratory tests were conducted in unidirectional waves with different wave conditions and pile porosity that varied from 0.0625 to 0.48. The i...
