数値計算による上甑島浦内湾の副振動特性の検討 [in Japanese] Numerical Study on Secondary Undulation in Urauchi Bay at Kami-Koshiki Island [in Japanese]
Access this Article
Secondary undulations locally called “Abiki” are frequently observed in Urauch Bay at Koshiki Islands. To take countermeasures against the secondary undulations,it is important to understand amplifying characteristics of Urauch Bay under various conditions. In this study,responses of Urauch Bay to several factors affecting amplification of secondary undulations were evaluated by numerical analyses. As the result,it is clarified that amplification factor depends on not only a period of incident waves but also amplitude or a composite effect of those. In addition,change of depth due to a tide and tidal current near straits at the mouth of Urauch Bay have affects on amplification factor of Urauch Bay.
