本署為經濟部災害緊急應變小組之水災防救幕僚機關，於颱洪期間成立災害緊急應變小組，負責執行「蒐集氣象、水文、蓄水庫現況與水災災情等資訊，經分析研判後適時陳報經濟部災害緊急應變小組，並發布水情通報與洪水預警報」。為因應水情預警報決策支援之需要，本署依據中央氣象局所提供之數值化網格降雨預報資訊，供予所屬各河川局進行各類水情資訊之水文分析與水理演算；並以網頁方式呈現即時水情預警資訊，俾據以評估未來水情與災情發展趨勢，以及提供擬定最佳防災整備與應變調度方案之參考。 上述各系統平台已陸續完成研發與建置工作，主要成果係以地圖化方式呈現全臺各鄉鎮市及河川流域之即時水情預報資訊，並於既有平台開發基礎上，建置水情預警系統入口網頁，以進行展示介面之適切統整與水情資訊之精進提供。此外，亦研發自動化預報雨量與河川水位流量之頻率分析功能；開發雨量預報與淹水預警之手機版展示網頁；另建置自動化水情預警簡報產製功能，俾為災情預警與情資研判時輔助之用；協助進行降雨預報之綜整、解析與提供等作業。此外，颱風豪雨時期則彙整各河川局所提供河川洪水預報資訊，俾供災害應變情資研判之用。

To fulfill the needs of flood early warning for Water Resource Agency(WRA) during flood season, the project executes the forecast data reception, collection and display including precipitation and water level, etc. Furthermore, the project analyzes aforementioned data and develops automation modules and intelligent systems to provide forecast information to users. The results may seem as the reference of disaster prevention preparation and contingency planning. Regular service and maintaining works include collecting the flood forecast information from ten river management offices and integrating them into a brief document based on specified form for decision support; optimizing the hydro forecast information integration display platform such as updating the basic information, adjusting layout of platform based on needs, integrating spatial rainfall information to show water level forecasts from multiple sources; resolving the data of dual polarization radar at Nantun and integrating it into current rainfall data providing workflow and display platform; and maintaining forecast rainfall data providing server to enhance the stability of rainfall data processing flow. Technology research and development works include building an automated information dissemination system which collect water-related information and proactively send early warning messages to inform the relevant personnel; expanding the user-defined path function in the early warning expert system based on typhoon track to instantly search for the rainfall and damage caused by the historical typhoon under different typhoon paths to Taiwan; developing a rainfall forecast correction method to find the possible systematic errors of the rainfall forecast product based on observation data, and provide the adjusted product to the relevant units for reference.
