淡水河流域位於台灣北部地區,由三個主要支流匯集而成,即大漢溪、新店溪及基隆河,淡水河流域面積為2,726km2,標高20m以下平地則為243km2,居住人口約6,500,000人,人口密集且為台灣首善之區。然而由於地形特殊,每遇豪雨或颱風時期,低漥地區常遭致淹水,因此,政府於民國五十年代開始陸續進行台北地區防洪計畫,如今已完成堤防長度共計68,100m,水門123座,抽水站79座,疏洪道1座,排水工程及橋樑改建工程。自1996年起,台北地區已能達到二百年頻率的高保護防洪標準,歷經1998年瑞伯及芭比絲颱風、2000年象神颱風、2001年納莉颱風,該計畫均已發揮一定的防洪功能。 而基隆河自南港以上河段則尚在進行堤防興建及排水改善工作,目前最多僅能達到10年頻率的防洪保護標準,因此,基隆河沿岸地區每遇豪雨即造成河水氾濫成災後續基隆河整體治理計畫係以保護基本治理計畫200年發生一次洪峰流量所產生之洪水災害為標準故基隆河整體治理採分洪、滯洪、河道治理及洪氾區管制等縱合措施,達成洪災防範之目標。以長期治理觀點而言,非工程措施如洪水預警報系統、集水區管理、易淹水地區都市更新規劃及防災觀念教育與宣導等落實,使洪災造成之生命財產損失降到最低,以達洪災消滅之效果,此乃為整體治理之目的。
The Tamshui River Basin is situated in northern Taiwan. Its major tributaries include Ta-Han River, Hsin-Tien River and Kee-Lung River. The basin area approximates 2,726Km2, of which 243Km2 plains area lies below an elevation of 20m. The basin is well developed and heavily populated with a population of approximately 6.5 millions. Low-lying areas in the basin are susceptible to flooding due to unique topographic features of the basin. The government started the Greaten Taipei Metropolitan Area Flood Control Project in the 1940's. Structural flood control facilities completed in place as of today include 68, 100m of levees, 123 flood gates, 79 pump stations, 1 flood relief channel, and other drainage works and bridge opening improvements. Flood control in the Greater Taipei Area with a protection level of 200-yr flood has been achieved by 1996 except the kee-lung River basin above Nan-Hu Bridge. The project accomplishments have gone throngh the tropical storms of Typhoons Zeb and Babs in 1998, Typhoon Xangsane in 2000 and Typhoon Nari in 2001, and functioned well as intended. Nevertheless, levee construction and drainage improvements in the upstream reach of the tributary of the Kee-Lung River. above Nan-Kang, where present flood protection level is about 10-yr flood and the area is flood-prone, are still in progress. The flood protect ion level for the Kee-Lung Rver Flood Control Project will be upgraded to 200-yr flood eventually. Flood control measures undertaken for this project include flood flow diversion, flood detention, river channel improvements and flood plain management. In addition, non-structural measures such as flood warning and alarm systems, watershed management, renewal planning for flood-prone urban areas, and enhancement of the public's awareness of disaster prevention should also be undertaker in order to mitigate flood damages and reduce casualties and property losses to a minimal extent.
