Abstract

<p> To evaluate the performance of wave dissipation structure, cross-sectional experiments has been performed to measure the reflectance coefficient. However, this method is insufficient, because waves sometimes propagate to a dissipating wave structure in the oblique direction. In constant, in an experiment using a plane water tank, multiple reflections of waves are generated. Thus measuring the flow velocity and wave height is difficult, so that. The experimental conditions that can be examined are limited. Therefore, we studied the oblique incident based on numerical calculation. The results of numerical calculation were generally consistent with the measured values in our experiment. Thus, it is expected that overtopping at oblique incidence using numerical calculation in the future.</p>
