NONLINEAR WAVE TRANSFORMATION OVER A SUBMERGED TRIANGULAR BREAKWATER

Lifen Dong, Akira Watanabe, Masahiko Isobe

Abstract


This study deals with wave transformation over a submerged triangular breakwater that is composed of a series of elements with a triangular horizontal crosssection. The idea of such a triangular breakwater is founded on the use of the wave refraction due to peculiar spatial change in water depth around it. A numerical model is developed to predict nonlinear wave transformation over and around the breakwater on the basis of fully nonlinear wave equations proposed by Isobe (1994). Laboratory experiment has also been conducted in a wave basin. The validity of the numerical model is examined by comparing the computations with the measurements.
