Combined diffraction and transmission of water waves around a proous breakawater gap

摘要

An analystic method for the combined diffraction and transmission around a porous breakwater gap is presented.the method cna be usmmarized as follows.First of all,it is necessary to decompose the incident wave into two components,according to the incidence angle and the permeability of the two breakwaters that form the gap.then,let the breakwaters be completely transparent to the relevant component of the incident wave and ascertain the transmission field.next treat the breakwaters as solid to the other ocmponsent of the incident wave and solve the diffaraction field.
