Abstract

A wave equation is presented for predicting reflected and transmitted waves for a permeable submerged breakwater. This equation includes the mild slope equation derived by Berkhoff(1972), which is a vertically integrated refraction-diffraction equation. Therefore, the equation derived can also predict the combined effects of refraction and diffraction. Numerical calculations with a dissipation term due to breaking are performed to obtain reflection and transmission coefficients as well as wave height distributions. Through the comparisons with the experimental results, the validity of the model is confirmed.
