中文摘要 | 淡水河流域目前有石門及翡翠兩座水庫,除在平時可攔蓄水量以供河川低水流量 季節利用外,在洪水時期則可執行調洪及減洪之工作。兩水庫由於集水面積(石門及翡翠兩 水庫分別為 763.4 km �握� 303km �插^合計約佔淡水河全流域面積(集水面積為 2,726km �插^之四成( 39.12% ),因此對流域下游地區洪水位(量)之調節便顯得重要,在颱洪時 期,倘吾人能掌握先機預先對兩水庫採取必要之措施,則可有效防範水患災害於未然而大幅 提高人民生命及財產安全之保障。大臺北地區,除繼續完成各項既定防洪工程之硬體設施外 ,尋求其他非工程結構性之措施-例如於防洪時期,利用淡水河流域兩水庫來調節洪水以消 減洪患,亦不失為另類有效解決方法之一。惟過去乃至目前,吾人對於該兩水庫之防洪操作 ,尚未有人提出量化之充份數據,以彰顯彼等對調節淡水河下游地區洪水量以達減洪目的之 成效。本文利用過去颱洪事件以及石門及翡翠兩水庫實際防洪操作之記錄資料,分析兩水庫 對淡水河流域下游河道洪水位(量)減洪之成效,並進一步探討兩水庫及其防洪操作對淡水 河流域下游地區洪水量之影響。本研究較著重實務應用面,該項研究結果可提供作為水庫防 洪操作決策、淡水河洪水預報以及大臺北防洪檢討等利用。 |
英文摘要 | The purpose of this paper is to provide the results of a preliminary study on the mitigating effects during floods in Tan-shui River system, due to reservoir operations by Shihmen and Fei-tsui Dams. As far as the safety of reservoir is concerned, the current operation rules are employed during the simulations. The simulated results demonstrate that suitable reservoir operations will be able to mitigate the downstream flood disaster. It is hoped that this preliminary study may help to initiate a better solution, a non-structural measures, to the flood control as well as water resources conservation without jeopardizing the dam safety in a near future. |
