ANALYSIS OF SOLITON RESONANCE BY USING FULLY-NONLINEAR AND STRONGLY-DISPERSIVE WAVE MODEL

Abstract

 Many investigations related to soliton resonance with the large initial amplitude of surface waves have been done in the previous studies by using numerical computaions and laboratory experiments. However, less attention has been paid to small intitial amplitude waves in the analysis of soliton resonance. Therefore, this study aims to investigate soliton resonance with the initial amplitude of 10 % of the total water-depth for surface waves by using the fully-nonlinear and strongly-dispersive wave model. As a result, the amplification rate was found to reach to 3.6 times as large as the initial amplitude. Also, the large amplification rate was found to appear when the initial shape of a solitary wave can be modeled by the KdV theory.
