中文摘要 本研究引進由西班牙Cantabria大學所發展之整合型海岸模擬軟體SMC (Coastal Modeling System)。SMC軟體包含許多模組,各個模組之間的連結良好、運算速度極快,使用軟體視窗化,可於桌面上直接作業。海岸結構物設計時,地形水深檔會自動修正等等優點,使得操作及應用上相當方便。本模式應用於台灣海岸時,可建置台灣周圍海域之地形及海氣象資料庫與SMC軟體互相配合,或因應台灣海域之特性新增模組於SMC軟體內,建立完整地台灣海岸設計規劃及防災軟體。
文中先對SMC軟體內各個模組的功能逐一介紹,並對SMC軟體內波、流場之理論基礎作一簡述。為了證明SMC軟體模擬波流場之正確性,本研究引用許多試驗數據及其他數值模式之結果與SMC模式模擬之結果比對,包含Berkhoff橢圓形淺灘、波浪通過結構物及現場實例等之驗證。校驗結果顯示SMC之適用情形良好,且SMC模式不論與試驗數據或數值模式的比較皆有極佳之成果。
海岸設計規劃方面,本研究選定安平港北側至漁港南側之海域,進行海岸規劃設計之實例應用。海岸結構物之佈置條件為在安平港北堤及漁港南堤兩處各增設一突堤,並配合靜態岬灣理論施以人工養灘,設計灘線位置為原灘線向外35公尺處,以夏、冬兩季季風及50年迴歸期SW向和W向之颱風波浪條件,模擬設計前與設計後當地海域地形變化之差異。由模擬結果發現,原先颱風侵襲時,將會對當地海岸造成侵蝕現象;在配置馬刺突堤後,颱風波浪之能量可以有效地被突堤分散,使近岸處之波高和循環流流速減低,達到保護海岸的成果。
英文摘要 In this study, The Coastal Modeling System (SMC) which was developed by Cantabria University in Spain is introduced to Taiwan coast. The SMC includes many modules:(1) Pre-process Module; (2) Short-term Module; (3) Middle and long term Module; (4) Field Module; (5) Tic Module. There are many excellences such as the connection of each modules is great, the rate of compute is much fast and Window-based, software will automatically revise the topography file when designing the coastal structure. This makes the SMC flexible and simple in the operational stage. When applying the SMC software in Taiwan, we can build a data bank of bathymetry and wave climate which are connected with SMC software to describe wave transformations and morphodynamics around Taiwan coast. We can also additionally develop a new module, like typhoon module, especially for Taiwan coastal waters.
Before introducing SMC to a real problem at Anping coast in southern Taiwan, a series of model tests have been performed to validate the capability of each module, including wave and current modules. The numerical results are compared with available experimental data. The results show that the applicability of the SMC is in good agreement with experimental data.
In practical engineering application, we apply the SMC software to Anping coast. The hydrodynamics before and after construction of two groins in Anping coastal waters is studied. The area of groin construction is located between Anping harbor in south and a fishing port in north, in which one groins is attached on the northern breakwater of Anping harbor, and the other is attached on the southern breakwater of fishing port. The headland theory and artificial beach nourishment are also adopted to design shoreline extension of thirty five meter in offshore direction. The SMC is implemented in simulating and comparing the topography before and after designing with summer monsoon, winter monsoon, typhoon in SW and W direction wave conditions. The results show that typhoon causes erosion at Anping coast before groin construction; after the construction, the wave energy will be dispersed to achieve the goal of protection to the coast.
