정현형 지형과 다양한 외부흐름에 의한 반사 = Resonant Reflection by Sinusoidally Varying Topography with Various Shear Currents

다국어 초록 (Multilingual Abstract)

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.

정현형 수중구조물과 파랑의 공명을 이용하여 파랑의 에너지를 감소시킴으로써 파랑으로부터 해안 시설물을 보존할 수 있다. 파랑은 해저지형뿐만 아니라 외부흐름과의 상호작용에 의하여 변형한다. 본 연구에서는 정현형 지형과 다양한 외부흐름에 의한 공명을 해석하였다. 수심과 외부흐름의 경사를 작은 구간의 계단형으로 단순화하였다. 계산에 필요한 적절한 구간의 수를 제안했으며, 소멸파 성분 고려 여부에 따른 차이를 보였다.
