碩士 === 東南科技大學 === 防災科技研究所 === 98 === The influence of surface waves scattering by undulating seabed such as sinusoidal bars has been studied, the characteristic of multicarrier impermeable sinusoidal submerged breakwater are investigated experimentally in this article utilizing regular wave, the interaction between waves and the obstacles are discussed by the reflection coefficient and transmission coefficient, the experiments are carried out with various composition of breakwaters collocated with various wave conditions, i.e. different wave period and wave height, the optimization of sinusoidal breakwater are therefore discussed. As the results revealed, desperate diversity are found in the reflection coefficient due to varied height of the breakwater under the circumstances of various wave conditions, i.e. wave height and wave period, whereas the diversity of reflection coefficients are mitigated due to varied width of the breakwaters, furthermore, the reflection coefficient increased accompany with the increasing of breakwater’s width and height, generally. The effectiveness of the dissipation and the optimization of the disposition of sinusoidal breakwaters are therefore discussed.
