商品簡介
有鑑於中社海堤區域灣域為天然岬灣且富珊瑚礁,若貿然將現況突堤延長或佈置其他防護工程,恐對現有天然海岸生態環境造成衝擊。故此計畫針對海象環境之潮汐、波浪及漂砂進行觀測研究,在全面性考量後提出適當之海岸防護方案,為日後海堤設計與管理維護,提供更具完整性之參考建議。
本計畫執行時間自民國98年6月至99年5月,工作項目及內容:(1)基本資料蒐集整理分析。(2)海岸地形水深測量及斷面測量。(3)中社海岸海象資料調查。(4)中社海岸生態資料調查。(5)中社海岸防護工法研擬。(6)海岸景觀營造。(7)工程改善方案及經費概估。(8)舉辦地方說明會。
Jhong-She, the western village of Wang-An island, has been managed to maintain a natural reefy coast. Jhong-She fishery port is an artificial port comprised north and west breakwaters. In order to provide better sheltering and reduce incoming storm wave height in the harbor, the 45 m long groyne southwest side of the fishery port had been constructed in 2006 by 7th River Management Office, Water Resources Agency, MOEA. The major work in this project is to study a valid coastal protect plan to improve the defense of Jhong-She fishery port against storm wave attack.
The main work of this project include the collection of background data, field measurement of wave and bathymetry. Using numerical simulation will be further studied a valid coastal protect method. The following tasks have been carried out in this year: (1)Historical data collection and analysis. (2) Bathymetry survey. (3)Wave climate monitoring. (4)Numerical simulation of nearshore hydrodynamics. (5)Landscape resource evaluation. (6)Marine ecology monitoring.
