近年全球氣候環境異常，頻繁引發水文極端現象，若能充分掌握與分析水文資訊，適時提供相關管理單位，預作必要因應措施，將可降低天然災害造成之損失。此外，開發低污染或無污染性之再生能源(renewable energy)已成為全球能源產業主流，而水力能為再生能源之一，故推廣水力發電與提高發電效能，勢必將成為未來電源開發之重要選項。依據台灣電力公司民國84年全台水力普查結果，水力發電尚待開發約為2,967MW，故若能配合最新地形與水文資料，重新檢視各地區水力蘊藏量分布，將可增加能源開發之選擇性與可利用性。再生能源中水力發電開發計畫及後續水工設施維護管理，與開發區位流域之地形、水文、水理等特性相互關係影響，因此水文資訊之掌握實為當前重要課題。若可應用地理資訊空間與數值高程資料，結合傳統水文水理分析技術，將可大幅提升規劃與管理單位於水文分析與設計工作之效率。台灣電力公司於105至107年度間完成「秀姑巒溪流域水文與水力蘊藏量分析整合資訊平台」計畫，應用開放原始碼地理資訊系統，整合地形分析、水文學、水力學理論，建置「水文與水力蘊藏量分析整合資訊平台」。本計畫以前期計畫為基礎，針對台灣東部水力蘊藏量豐沛地區-和平溪、南澳溪及花蓮溪流域，整併數值高程資料及數化圖資，建置河川網路空間資料庫，納入現有「水文與水力蘊藏量分析整合資訊平台」。並擴充現有分析計算模組，針對高潛能發電位置，依據其地形特性、可能發電量、發電形式、壩址-廠址距離等因子，初估水力發電主要工程設施之可能費用，藉此作為水力發電選址之參考；新增「特定壩址水力蘊藏量分析模組」，提供使用者針對特定壩址進行線性水力蘊藏量分析，使「水文與水力蘊藏量分析整合資訊平台」更臻完善。本計畫另以Web-GIS技術建置「水文與水力蘊藏量資訊雲端系統」，透過介接即時水文資料與各類開放圖資，並整合「水文與水力蘊藏量分析整合資訊平台」之分析成果，進行基礎圖資瀏覽、地文因子查詢、即時水情查詢、水力蘊藏量資訊上傳與查詢、即時淺層崩塌潛勢區域分析等工作，相關成果並將以空間資料型態發布於網際網路，透過簡單且直覺的地圖與友善操作介面，提供水力資源開發工程規劃參考與維護管理之應用，達成即時傳遞與資料共享之目的。 In considering that the hydropower development plan and subsequent hydraulic facilities maintenance are related to watershed topographic and hydrological characteristics, hydrological analysis work should be conducted efficiently by using the digital elevation models and GIS technologies. Moreover, due to climate variations and environmental changes in recent years, hydrological extremes are more frequent than before. If a web-based platform can be developed to provide the time-varying hydrological information and delivery to the related hydropower plants in time, the losses caused by natural disasters can then be reduced through applying adequate disaster prevention measures. This project integrates digital topographic information and hydrological methods to build up a hydrological and hydropower analysis platform for Heping River, Nanao River, and Hualien River basins in Eastern Taiwan. By using the analysis platform, users can select any point on the river network within the watershed, to perform rainfall analysis, flow analysis, probable maximum flood analysis, landslide analysis, hydropower analysis, discharge-sediment concentration analysis, and annual sediment-discharge analysis. Moreover, for high potential hydropower locations, the possible costs of the major hydropower facilities can be estimated according to local topographical characteristics, hydropower potential, hydropower generation form, and headrace for reference. Based on the Web-GIS technology, a cloud platform was also developed to link the real-time observed data and the analysis results generated from the hydrological and hydropower analysis platform. Users can browse the analysis result maps, check the real-time hydrological information, query the hydropower analysis results, and real-time shallow landslide analysis on the internet. Through an intuited and friendly operation interface, the cloud system can provide vital hydrological information for real-time hydropower facilities maintenance and management. "
