縣市水災防救整備、應變及復建等工作的推動過程中，水情中心的運作效率將影響整體工作執行的成效，因為縣市水情中心是縣市水災防救業務執行時與中央部會和地方區里單位的橋梁，同時也是水災情資訊彙整、加值和發布的整合單位，如果業務運作過程中無法即時接收、分析和傳送水災情資訊，將可能錯過應變作為執行的黃金時間，導致減災與避災工作成效不如預期。但是目前縣市水情中心的運作，尚缺乏高效能的資料庫整合平台、即時積淹水潛勢評估模式和決策支援系統，所以本研究目標就是要提出一套即時水災情資訊彙整、加值及發布的系統概念。因為2010年凡那比颱風重創臺灣南部地區縣市，尤其是高雄市的淹水災情最為嚴重，本研究與高雄縣政府水利局和國立成功大學防災研究中心合作，於高雄市水情中心來架構本研究所提出的概念系統。本研究所提出的系統應用Google雲端處理技術、地理資訊系統、即時積淹水潛勢評估模式和微軟互動式網路平台等先端工作，並有效的改善過去高雄市水情中心執行業務面臨到的幾個課題，包括有避難疏散資訊的不全、防救災資源調度狀況掌握不易和災害現場資料不足等問題。

For regional flood prevention and response, an effective flood emergency operation center is crucial for the regulators and managers responsible for planning and coordinating a community's preparedness, response and recovery efforts. However, a flood emergency operation center, which has empirically documented links between data bases of hydro information, real-time inundation models and a flood decision-making system, is rare for local governments. Therefore, the aim of this article is to explore how hydro information, real-time inundation models and a flood decision-making system can be integrated to improve the efficiency of flood emergency operation centers. This research involved a case study, namely a local government located in southern Taiwan that suffered a severe flood disaster in 2010 and cooperated with the Disaster Prevention Research Center of National Cheng Kung University (NCKU) to plan and set up a modern flood emergency operation center. Various information techniques are used in the system including Google techniques (Google File System, MapReduce and Google BigTable), GIS (Geographic Information System), the Physiographic Inundation Model and Microsoft Silverlight. Results of this study provide solutions to problems associated with emergency situations, i.e., inadequate evacuation guidelines for people, incomplete geographical information for relief workers, and insufficient on-site information for disaster managers.
