本計畫針對碎波帶內波生流之水動力及擴散係數特性進行基礎性及實務性研究。研究內容以臺灣東北角福隆海岸為研究動機，即針對其實際海岸特性規劃出四年期的基礎研究，內容包含(1)建構適用於近岸海域尺度的三維大渦波浪及粒子擴散模式、(2)大型平面水池模型試驗(包含規則波浪與不規則波浪)的波生流試驗(包含定床與動床試驗, 浮標估算擴散係數)及空拍水深技術改良及(3)福隆海岸現地量測(包含近岸流場、水平擴散係數及碎波帶內地形)。研究成果將包含波生流特性的學理研究與實務應用。本計畫成果也可作為此海域親水遊憩管理策略及沿岸輸砂管理策略等相關議題之參考依據。The project aims to investigate characteristics of wave-induced hydrodynamics and dispersion coefficient in the surf zone. The study is motivated by the nearshore region of Fulong coast. The goals are (1)a development of three-dimensional large eddy simulation wave model and particle tracking model particularly for nearshore coast.(2)a large-scale laboratory experiment on three-dimensional wave-induced nearshore hydrodynamics subject to regular and irregular waves. The effects of movable seabed is also performed to verify the difference between years 2 and 3. The evaluation of Unmanned Aircraft System on estimation of water depth in the surf zone is also carried out. (3)the field measurements on nearshore hydrodynamics and horizontal dispersion coefficient along Fulong coast. The coming results in this project could be applied to coastal management policy, including coastal recreation, alongshore sediment transport and coastal erosion.
