中文摘要	針對豪大雨對海水浴場水質影響進行較深入探討，內容包括於福隆和旗津海水浴場進行每場次連續五天各十場次之密集水質監測，監測項目為大腸桿菌群、腸球菌、鹽度和濁度。並擬定之休憩海域密集監測標準作業程序，包括計畫規劃、採樣與監測及研判結果與具體建議等。以累積50小時雨量做為衡量水質變化有較好的相關性。福隆、旗津海水浴場水質均受雨量(尤其颱風雨)明顯的影響。旗津水質較佳，受降雨影響時間較短，復原也較快，雨停後約一~三天即可恢復正常水質。福隆則較長時間，復原約需三~六天。每一海水浴場密集監測降雨時水質是有必要的，但分成左中右三個測站，水質監測結果沒有顯著差異性，建議往後可改為中測站即可。福隆水海浴場海水之鹽度若小於10.3 ?或13.6 ?的情況下，大腸桿菌群或腸球菌準有很高的機率會超過水質標準。針對福隆、崎頂及旗津海水浴場五公里半徑範圍內之污染源進行調查，主要調查污染類別包括生活污水、工業廢水、畜牧廢水、海洋放流管、河川污染、降雨時之濕沉降及其他非點源污染等。透過採樣時之污染現堪紀錄，整理出海水浴場之污染管理建議，供經營者參考。就海域休閒遊憩區之污染防治及管理措施，進行文獻收集整理，條列出各種污染管理可採行之管理措施，供主管機關擬定管理策略之參考。估算旗津海水浴場之逕流量，以合理公式所得約為單位歷線法之1.2倍，自降雨再經由第一港口擴散至外海約4.5小時以上，才會影響海水浴場。最大尖峰逕流量由合理公式得為506CMS，經驗公式估得為366CMS。福隆海水浴場以合理公式估算者約為台電實測水位經驗法估算之三倍，尖峰逕流約在降雨後28.79小時影響到海水浴場。崎頂海水浴場除由小型排水溝渠所直接排入海水浴場鄰近海域外，不易受到中港溪污染，且其須在尖峰逕流抵達河口之後經8.3小時才會受到洪峰污水影響。福隆海水浴場逕流量對水質影響，初步分析逕流量超過90CMS時，即可能造成4~5天之水質變差。最後，建議海水浴場水質須要更深入研究以便收集到足夠數據供做為較佳管理決策之參考依據。

摘要	This project is designated to perform intensive recreational water quality monitoring of the Taiwan coastal area. Studied beach resorts include Fu-Long beach, Chi-Ting beach and Chi-Jin beach. Main objectives of this project include (1) the investigation of rainfall effects on the beach water quality, (2) the investigation of pollution sources andto propose the best management practices, (3) to estimate run-off flux of rainfalls, and to estimate run-off effects on the beach water quality. Finally, a standard operation procedure (SOP) is proposed for the future beach water sampling activities.To study the effects of rainfalls on the beach water quality, ten major rainfall events are studied. In order to propose a critical timing to close the beach and to investigate the water quality recovery efficiency, each sampling activity requires at least five consecutive days. Parameters investigated include coliform group, enterococci, urbidity, and salinity.Results indicate 50-hour rainfall amount has better correlation with bacteria counts which is proposed as a decision making tool. The beach water quality takes about 3~6 days to recover to normal in Fu-Long beach resort, and only takes about 1~3 day to recover in Chi-Jin beach for a better current circulation. In terms of rainfall effects on the beach water quality, no conclusive result obtained because the collected data is not statistically significant to make conclusion. However, it is conclusive that the beach water quality was significantly affected by the rainfalls. However, it is conclusive that three sampling locations in a beach is not necessary, and suggest to use the center location for future sampling activities. Our preliminary results also indicate that at Fu-Long beach, coliform group will likely exceed beach water quality standard when the salinity drop down to below 10.3 ?, so as enterococci at 13.6?.
