홈페이지논문 초록 (Abstract)
Breakwaters are generally constructed to protect the port and harbor fac ilities from dynamic forces of the ocean wave. However, the stability pr oblem of breakwaters has been issued due to the global warming, which ca uses the rising of sea level. A submergedstructure, most effective meth od for resolving such problems, can be expected to improve the stability and the practicality of the breakwater. In this study, a rectangular sh aped submerged structure is chosen because it has known as the most effi cient oneamong other shapes in the literature. Based on results from la boratory experiments, the reflection coefficient and the run-up height o f breakwaters are investigated for different widths and heights of the s ubmerged structure with different distances betweenadjacent two breakwa ters. As the results of experiments in this study, the reflection coeffi cient decreased as the wave steepness increased. The run-up height decre ased because the wave breaking and reflection due to a submerged structu re, when the heightof a submerged structure relative to flow depth was high. Therefore, the dissipation of the incident wave energy can contri buteto improve the stability of the rubble-mound breakwater more stable . The results from this study would be utilized as the basis of the desi gn of a submerged structure.
