本計畫探討不規則波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，推導不規則波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)，模擬不規則波通過系列潛堤的布拉格反射。並進一步利用試驗進行驗證用以校驗數值模式之適用範圍。同時應用波浪數值模式於特定海域以進行系列潛堤研究，並評估各種複合式系列潛堤配置方案之防禦功效。 In this project, the Bragg reflection for irregular waves propagating over a series of submerged breakwaters is investigated. Based on Miles？HHH？HHH (1981) theory, the wave reflection coefficient for wave propagation over various composite submerged breakwaters is first theoretically derived. The wave model of EEMSE developed by Hsu et al. (2001) is employed to simulate the Bragg reflection of irregular waves passing over a series of submerged breakwaters. The experiments are also performed to verify the validity of the numerical model. The Bragg scattering of water waves propagating over various composite submerged breakwaters is assessed by numerical calculations to examine the usefulness of protection
