潛堤의 反射 및 透過率에 關한 硏究 = A Study on Reflection and Transmission Coefficient of Submerged Breakwater

다국어 초록 (Multilingual Abstract)

The reflection and transmission effects by the change of space and size of the rectangular submerged breakwater installed in the constant depth of sea-bottom water were theoretically estimated and investigated by the potential connecting method and two dimentional hydraulic model test. In case of impermeable submerged breakwater, as it were, the effect of width, space and height of submerged breakwater were investigated sperately by the theoretical analyses and experiments on single and double submerged breakwaters. And, in the event of permeable submerged breakwater, space and height of submerged breakwater were investigated by experiments.
According to this study, the following conclusions were obtained.
1) The theoretical and experimental values were very close in their numerical values in impermeable submerged breakwater.
2) The influences width and space of submerged breakwater on reflection and transmission effects were not constant but the repetition of increase and decrease and its influences became more greater as the height of submerged breakwater was more higher.
On the contrary, there were little influences of width and height of breakwater on reflection and transmission effects in permeable submerged breakwater.
3) Double submerged breakwaters was more effective in wave damping effects than those of single submerged breakwater in impermeable submerged breakwater.
4) Wave damping effects of impermeable submerged breakwater were more greater than those of permeable submerged breakwater.
