Analytical Method for the Wave Diffraction of Asymmetrically Arranged Breakwaters

The layout forms of several breakwater structures can be generalized as asymmetrical arrangements in actual engineering. However, the problem of wave diffraction around asymmetrically arranged breakwaters has not been adequately investigated. In this study, we propose an analytical method of wave diffraction for regular waves passing through asymmetrically arranged breakwaters, and we use the Nyström method to obtain the analytical solution numerically. We compared the results of this method with those of previous analytical solutions and with numerical results to demonstrate the validity of our approach. We also provided diffraction coefficient diagrams of breakwaters with different layout forms. Moreover, we described the analytical expression for the problem of diffraction through long-wave incident breakwaters and presented an analysis of the relationship between the diffraction coefficients and the widths of breakwater gates. The analytical method presented in this study contributes to the limited literature on the theory of wave diffraction through asymmetrically arranged breakwaters.
