Three-dimensional Variation of Wave Transmission around the Artificial Reefs: An Experimental Study

초록

In this study, three-dimensional experiments were conducted to investigate the spatial variation of wave transmission characteristics under the different types and configurations of the artificial reefs. Partially permeable armored by tetrapods and impermeable structures were deployed with the different gaps. Incident wave conditions included both breaking and non-breaking conditions over the structures. Transmitted wave heights in cross-shore and alongshore directions were compared with the empirical formula. The results showed that the wave transmission phenomena were dependent of the structural type, layout, and gap distance. In the case of single structure, as the length of the structure increased, the transmission coefficient decreased. In the case of multiple structures with a gap, the length of the structures and the gap were inversely proportional to the transmission coefficient.
