由於水庫每逢颱風或豪大雨過後常導致濁度(Turbidity)飆升現象,造成供水停擺,然而翡翠水庫為大台北地區的主要供水水庫,為了防範此現象發生,須有長時期觀測濁度變化系統,以達到監測效果,因此本研究採用遙感探測(Remote Sensin,RS)可即時且大面積觀測之功能,並搭配遺傳運算樹方法(Genetic Algorithm of Operation Tree,GAOT)進行分析,建立衛星影像與濁度間之關係式,研究結果顯示模式之相關性(R)達0.8294,因此應用遙測技術可快速有效觀測大範圍水庫濁度之變 Because the typhoon and storm results in the turbidity increasing frequently,the water demand may not be supplied normally. Feitsui Resrvoir of the case study is the major water source in Taipei area. In order to prevent the serious situation mention abov
