초록

The resonant reflection caused by sinusoidally varying submerged structure and wave could protect coastal facilities from wave attack by reducing wave energy. Water waves deform by not only bottom topography but also interaction with shear currents. In this study, a resonant reflection by a sinusoidally varying topography with various shear currents is investigated. The water depth and the slope of shear currents are represented by a finite number of tiny steps. The proper numbers of steps are proposed and the effects of evanescent modes are shown.
