本計畫探討波浪通過系列潛堤發生布拉格反射效應。理論解析方面以Miles (1981) 的理論為基礎，推導波浪通過各種複合式系列潛堤佈置之反射率結果；波浪數值模式上採用Hsu等人 (2001) 所發展演進型式緩坡方程式(Evolution Equation for Mild-Slope Equation，EEMSE)，模擬波浪於二維平面上通過各式系列潛堤佈置所產生的布拉格反射現象。最後，應用波浪數值模式於台灣特定海域以進行各項系列潛堤研究，並分析評估各種佈置方案之防禦功效。 In this project, the Bragg reflection for waves propagating over a series of submerged breakwaters is investigated. Based on Miles’ (1981) theory, the wave reflection coefficient for wave propagation over various composite series submerged breakwaters is first derived. The wave model developed by Hsu et al. (2001) is employed to simulate the Bragg reflection of waves passing over a series of submerged breakwaters. Various composite series submerged breakwaters are assessed by numerical results.
