The study area is enlarged in the third year study and contains the Central District, Hsien-Ten city and Shi-Ji city. The urban inundation model is applied to simulate the s face inundation in the study area for the Typhoon Zeb event and under the 2 -hour design rainfalls of different return periods with the operation of pumping stations and flood-gates. The study area located in the heart of Metropolis Taipei is selected as the study area, which includes Taipei Downtown, Hsien-Tehn city and Shi-Ji city o Taipei County. The rainfall data, geographic features, capacity of pumping station and flood gate operations are put for numerical simulations. The Typhoon Zeb event occurred in Oct 1998 is used for model verification. The an inundation model is applied to simulate the surface inundation in the study area under the 24-hour design rainfalls of 5-, 10-, 25-, 50-, 100-, and 2 0-yr return periods. Three sets of scenario simulation including (1) all of th pumping stations and flood gates are in the condition of normal operation, ( Shinshan, Shunyuan, and Foyuan pumping stations fail to operate, (3) Tansui No. 3, Keelung No. 4, and No. 9 floodgates cannot be turned off in time. The results are compared to be in good accuracy and assist the authorities concerned in proposing strategies for flood hazard mitigation plans.本研究屬於「台北都會區淹水區域預測之研究」整合計畫中之子計畫五「抽水站與閘門操作對都會區淹水影響之研究」全程三年計畫的第三年計畫，本年度研究區域擴大為台北中央區、台北縣新店市及汐止五堵地區，並完成瑞伯颱風雨不同重視期降與條件在各種不同閘門與抽水站操作方式下之模擬。 本文以台北中央區(含台北市原市區、南港區及文山區)、台北縣新店市及汐止五堵地區為研究對象，在將降雨及流量資料輸入後，配合地文資料與抽水站及閘門之操作情況進行地表淹水與雨水下水道之模擬演算，以87年10月發生之瑞伯颱風作為模擬驗證之依據，並完成進行5年、10年、25年、50年、100年及200年單日重現其降雨條件下之三種不同抽水站與閘門操作情況下之地表淹水模擬，包括(1)所有抽水站與疏散閘門均正常操作，(2)新生、雙園及撫遠抽水站無法正常操作，(3)淡水河三號、基隆河四號及基隆河九號疏散閘門未及時關閉等三種情況，研究結果顯示出本模式具有良好之精度，並可提供水利相關單位研擬水災防救措施。application/pdf7648933 bytesapplication/pdfzh-TW國立臺灣大學生物環境系統工程學系暨研究所Pumping-stationFlood-gateSewer systemSurface inundation收水站閘門雨水下水道系統地表淹水reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/10703/1/892625Z002005.pdf
