Interaction of Periodic Waves with Inclined Portable Barrier

Abstract

The two‐dimensional problem of the interaction of periodic incident waves with a hinged inclined barrier is investigated theoretically and numerically in this study. A combination of the finite element method and an eigenfunction expansion procedure is used to obtain numerical solutions to this problem. The transmission characteristics and the effectiveness of a partially floating, inclined breakwater are studied. The effects of variations in the wave period, angle of inclination of the barrier, and the bottom gap are investigated. It is shown that results obtained by the numerical method compare reasonably well with the experimental data and other theoretical solutions.
