本計畫之目的將以方向不規則波之變形為主要研究對象。研究內容分為水工模型試驗和數值模擬。前者利用國立台灣海洋大學之平面水槽，在等水深及均勻坡度之水深佈置離岸堤，量測波浪行經離岸堤之六大變形，即淺化、折、繞射、反射、碎波及能量消散等。本計畫水工模型試驗之配置如圖1 所示，造波條件包括不規則波及方向不規則波兩種。後者將使用 SWE，波浪頻譜模式以及緩坡方程式 MSE 模擬波浪通過離岸堤之變形。期望能從平面水池之試驗結果，校驗各種數值模式之適用範圍及其計算效率。 This integrated project includes four different numerical models and experiments on a large-scale wave basin to investigate wave transformation of irregular waves propagation over a detached breakwater on a sloping bottom. Wave nonlinear shoaling, wave-wave interaction, wave breaking and energy dissipation. All numerical results are compared and validated through experimental data. The project will be concluded during three years. The results are to be shared and submitted to international journals.
