本文主要是以有限差分法所建立的二維數值計算模式，來分析在造波板的運動下，潛堤、浮式防波堤及複合式防波堤等消波結構物與波浪間之互制(interaction)反應分析，並且討論能量在波傳過程的的變化。模式中亦考慮非線性( nonlinear )效應的影響，最後據以進行完整的實例分析，以分析波浪與結構物間的互制關係。

A time-independent finite-difference numerical scheme is developed to study the dynamic responses of both submerged , floating breakwater and composite floating breakwaters under wave force . The composite floating breakwaters is based on a moored floating bodies and submerged obstacle. The fully nonlinear kinematic free surface conditions and dynamic conditions are considered in the analysis .The numerical results were validated by several bench mark studies and existing reporting results. The wave reducing effect of both submerged, floating breakwaters and composite floating breakwaters were analysis and discussed。
