103年度四河局轄區洪水預警及防汛整合作業(附光碟)

濁水溪流經南投、嘉義、彰化、雲林等4縣21鄉鎮，沿岸人文社經活動居台灣關鍵地位；加強水患防災預警工作，除可保障社會、民眾生命財產安全外，並可提振地區經濟發展。本計畫實施將可更加健全洪水測預報系統模式運作，提昇測預報水準，並提供地方防災資訊。主要工作項目包括：洪水預警成果展示平台建置、國內常用降雨預報模式於濁水溪流域應用評估、納入陳有蘭溪流域雷達雨量修正模式、颱洪期間長期及即時洪水預報、颱洪期間水情調查、防汛宣導及防汛相關協助、系統維護與提供預報諮詢、交辦事項、技術支援及其它、編撰成果報告及簡報等工作。
1.順利完成本(103)年度5場颱洪事件之預警報作業，並於颱洪期間蒐集國內外相關氣象網站資訊，進行即時氣象資訊研判及推估濁水溪流域未來水情變化，予防汛值勤人員參考。
2.建置洪水預警成果展示平台提供即時與預測水情資訊，使相關防汛人員能更快速掌握轄區內水文變化，有效進行防汛應變決策。
3.完成本年度颱洪事件國內常用之各降雨預報模式於濁水溪流域運用測試，並提出初步運用建議。
4.於本年度颱洪事件期間，利用長期程預報模式，提前掌握颱風事件降雨分布及洪水規模；並利用短期程預報模式，掌握瞬間降雨變化及短期(1至6小時)之洪水位變化。
5.已協助完成1場颱洪事件水情調查及防汛手冊更新，並協助辦理仁愛、竹山鹿谷及大城地區等危險潛勢區防洪預警地方說明會，教導民眾防洪預警觀念，以落實全民防災。

The social and economic activities are busy along the bank of Zhuoshui river watershed comprising of four counties, Nan- tou, Chang-hua, Yun-lin and Chia-i, and including 21 villages or towns. To enhance precaution and preparedness against flood disaster not only protects social, public life and property, but also helps the development of local economies. The model of the flood forecasting system will be more mature, progression in the results of prediction and offer the disaster defense information will be improved after this project is implemented. The main assignments of the project include: Building the Flood Warning website, testing the domestic rainfall forecasting model in Zhuoshui river watershed, maintaining the stability and smooth functioning of the system of observation and forecast for runoff within the Zhuoshui river watershed, providing prediction analysis of typhoon information, technology supporting and assigned affairs achieving, report editing and presenting summarized below:
1.The work of precaution was executed successfully for the duration of 5 flood stage.
2.Builded the Flood Warning website can provided information of immediate warning and flood forecasting.
3.Complete the domestic rainfall forecasting model tested in Zhuoshui river watershed.
4.Before a typhoon arrived, we used the long-time model to provide for spatial distribution of precipitation and scale of flood peak for basin; during rainfall, we used the real-time model to forecast the next 1-6 hours Precipitation and flood.
5.Completed Flooding Investigation and held the public forum on the dangerous region of Zhuoshui river watershed.
