Experimental Study on the Wave Attenuation of Porous Pipe Breakwaters
The dissipation of porous perpendicular pipe breakwaters are studied experientially in this study, the investigations on wave transmission of the porous pipe breakwaters are carried out in the laboratory with different wave conditions and various combinations of pipe diameter and length. The wave energy is mainly dissipated due to the drag and interception of the resultant motion by the pipe breakwaters, the reflectivity of such effect are thus discussed by the evaluation of partly reflected and transmitted ratio, and consequently the performance of the pipe breakwater for predicting wave transmission coefficient is investigated. Experimental results revealed that the attenuation is much effective with the decreasing of pipe diameter than increasing of the length.
