104年度八河局轄區洪水預警及防汛整合作業(附光碟)

由於全球氣候變遷效應，臺東地區近年之颱洪事件日益嚴重，降雨量及強度皆有增強之趨勢。為達防災預警功效之短期目標，八河局於101年開始建置卑南溪洪水預警系統，俾於颱洪時期進行即時資料蒐集，並延續前期成果進行資料庫更新維護、系統擴充及更新、水文水理分析參數檢定驗證，完成洪水預警系統建置工作及防汛整合作業。 本計畫根據整體工作項目主要分為以下12大項，分別為更新維護洪水預報系統及相關水文地文資料、洪水預報系統模組之持續參數之檢定驗證、地圖化展示介面功能及圖資擴充、持續介接轄區內相關單位預警系統資料、提供水情資訊研判及諮詢、颱洪時期進駐協勤、颱洪事件預報結果分析、多來源定量降雨預報演算功能研發、洪水預報結果自動化產製與上傳功能研發、颱洪事件淹水災害調查工作、教育訓練及報告與簡報編撰印製。相較於前期計畫，今年度增加多來源定量降雨預報演算功能研發，為配合水利署需求，本計畫建置自動化依三種不同路徑ETQPF(預報路徑、極左路徑、極右路徑)預報降雨，模擬河川洪水位及可因應特定雨量預報輸入條件之嵌入式演算及輸出功能，以利後續洪水預報擴充利用。 本計畫除持續蒐集最新之水文資料、河道斷面資料、監視站資料、防汛資料、歷史致災資料及保全對象等，並針對系統部分進行基本資料更新，包括雨量站、流量站、河川斷面等，因今年度臺東地區尚未有較大之颱洪事件發生，維持103年度之檢定驗證參數，確保模式參數符合集水區現況水文特性。本年度持續更新八河局提供之圖層資料，包含新增縣管河川太平溪與知本溪水系基本圖資及相關基本資料。 今年度已完成104年度八河局轄區洪水預警及防汛整合作業之汛期前教育訓練，其課程安排配合河川局防汛之需求，包含堰塞湖應變手冊及演練操作流程說明、堰塞湖調查作業演練及相關儀器設備操作、淹水調查重點教學及流程說明、淹水調查作業模擬演練等4堂課，共計5小時。 本計畫已於今年度紅霞颱風、蓮花颱風、蘇迪勒颱風、天鵝颱風及杜鵑颱風期間，派員前往八河局進駐協勤，並提供相關事件之水情簡報。因今年度臺東地區尚未有較大之颱洪事件發生，並未啟動淹水現場調查工作。

Since the effects of global climate change, the flooding events in Taitung in recent years were increasingly serious. To achieve the effect of short-term disaster prevention and early warning target, the project began to build Pei-Nan River flood forecasting system in 2012. The systems help people to collecting instant information of the flood forecasting. The project continued updating database, expanding function of the system and flood forecasting integrating work.
Compared to the preliminary plan, the project added multiple sources of quantitative precipitation forecast calculation function development, to meet the needs of the Water Resources Agency. it built automation report which were according to three different paths ETQPF (forecast path, left path, right path) forecast rainfall simulation, and simulating river water level for the flood forecasts.
Before the flood season in 2015, the project had completed education and training of flood warning and integration operations. its included earthquake-induced lake operating procedures, the investigation of focused earthquake-induced lake and he investigation of flood.
The project had sent people to The 8th River Management Office, WRA and provided typhoon information and reports during the flood period of Typhoon Noul, Typhoon Linfa, Typhoon Soudelor, Typhoon Goni and Typhoon Dujuan.
