| Outline of Final Research Achievements |
Video footage of recent severe coastal inundation events due to tsunami, storm surge and stormy waves indicates that combination of waves with different frequencies has significant influence on amplification of coastal inundation. This study first developed a facility, which can generate waves with different frequencies including a bore to represent such wave-wave and wave-surge interactions. The numerical models were then developed for computation of such non-linear dispersive tsunami propagation with soliton fission and interaction of breaking and broken storm waves with storm surge induced by winds and waves. The models were validated through application to various experimental and field cases and it was confirmed that the model reasonably capture the observed amplification of inundation due to wave-wave and wave-surge interactions. The models and experimental facilities are readily applied for estimation of coastal hazard for designs of disaster mitigation.
