BREAKING AND REFLECTION OF A STEEP SOLITARY WAVE CAUSED BY A SUBMERGED OBSTACLE

Takashi Yasuda, Masanori Hara

Abstract


A fully nonlinear potential flow theory is solved numerically but almost exactly for a solitary wave passing over a submerged obstacle by using BIM. Based on the numerical solutions, the refraction characteristics and the breaker type and criterion are made clear for a solitary wave up to breaking caused by a step.
