中社海岸位於澎湖縣望安島西側中社村，港口朝南地勢平坦單調，無高山亦無河川，海岸多彎曲，附近海中多暗礁，潮流險惡。當地居民靠海為生，漁港為村里船筏基地。居民住宅緊鄰海堤後側道路，附近有保存完善之古厝聚落及天台山崗丘草原帶等觀光資源，每當大潮或颱風侵襲時，常發生波浪越過堤頂至海堤後側路面及民宅之情形。為保障居民之生命財產安全，並考量環境景觀視覺下，地方建議於中社海堤外海處已經設置之45公尺突堤予以延長，以達大浪碎波於外海，以減少海浪越堤造成堤後淹水難退之情形。
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.
