Abstract

A phase-resolving wave model, combined with a two-dimensional depth-averaged current model, is developed to simulate a series of regular or random waves passing an L-shaped breakwater at an oblique angle. The near-shore wave processes, such as wave shoaling, reflection, refraction, deflection and wave breaking, and the wave-induced currents, such as flow circulation around the L-shaped breakwater, are all well reproduced. The model results of the mean wave heights and currents along 4 longshore and 6 cross-shore profiles generally agree well with the measured data, indicating the accuracy and robustness of the present model in simulating waves and currents around complex structures such as the L-shaped breakwater in this study.
