Two-Dimensional Wave Transmission through a Linear Array of Floating Breakwaters

Abstract

A method of numerical analysis on the wave diffraction and radiation by a linear array of identical three-dimensional floating bodies is newly developed by a wave source Green's function method. Using the numerical method, wave transmission characteristics through an infinite array of rectangular floating breakwaters and dynamic responses of these break waters are extensively studied, including directional characteristics of the transmitted waves. It is clarified that obliquely transmitted wave components are predominant behind the floating breakwater array when an incident wave length is less than a center-to-center distance between the neighboring breakwaters.
