Decomposition of Reflecting Waves by Hyperbolic Model

쌍곡선형 모델에 의한 반사파 성분 분해

  • Published : 1998.12.01

Abstract

An approach of decomposing the reflecting components is proposed by using the mild-slope equation of hyperbolic type which has the similar form to the shallow water equations. The approach is verified on Booij's problem and sinusoidally varying ripples. Inclusion of higher-order bottom effect given by chamberlain and Porter(1995) yields even more satisfactory results than the Berkhoff's mild-slope equation when compared with finite element solution or experiments.

천수방정식 형태의 쌍곡선형 완경사 방정식을 이용하여 파랑의 반사파 성분을 분해하는 방법을 제시한다. 모델의 반사파 산정능력을 평가하기 위하여 Booij 경사면 및 물결사주에 적용한다. Chamberlain and Porter(1995)에 의하여 주어진 수심경사제곱항과 수심곡률항의 효과를 포함하였을 때 Berkhoff의 완경사 방정식에 의한 결과보다 유한요소법 결과나 실험 자료와 비교하여 훨씬 만족할 만한 결과를 보여주었다.
