本年度將以卑南溪及四重溪流域為計畫範圍，以建置河川流域地質資訊系統理念，進行地質調查及建立地質詮釋，並將資料充分展示於地質資料系統中，提供後續各河川流域之管理規劃參考應用。

A geological Geographic Information System (GGIS) for the basins of rivers administered by the Water Resource Agency was established and periodically updated in the previous (2004-2014) projects. During 2004-2014, field verification was carried out in 24 river basins (including the Lanyang, Heping, Fongshan, Touchien, Jhonggan, Houlong, Da-an, Dajia, Wu, Jhuoshuei, Beigang, Puzi, Bazhang, Jishui,Zengwun, Yanshui, Erren, Agongdian, Gaoping, Donggang, Hualien, Xiuguluan, DanShui, and Huang River basins) to confirm and to establish the data sets of geo-hazard, geologic outcrop, aerial-photo interpretation, and geologic interpretation of these basins in the GGIS. The objectives of the 2015 project covered (1) collection of new data, (2) field verification of the Beinan and Sizhong basins, (3) system maintenance and user-interface development, (4) implementation of Web-GIS, (5) training courses, and (6) GGIS-application demonstration for bedrock erosion assessment. The total numbers of verification sites of the basin verified in Beinan and Sizhong River basins are 163, which include 39 rock outcrops and geologic structures, 112 sites of riverbed conditions, 12 of geo-hazards. The total numbers of geologic interpretation are 23. The verification results were compiled and built into the GGIS system.

這份報告是經濟部水利署水利規劃試驗所委託國立交通大學執行的「中央管河川流域地質資料查核-卑南溪及四重溪」計畫。計畫旨在更新和維護既有的流域地質資訊系統，並針對卑南溪及四重溪流域進行詳細的地質資料蒐集、現地查核、地質詮釋與建置。 報告內容涵蓋了： * **資料蒐集與建置**：更新並新增了多項地質基本圖資，並蒐集了卑南溪及四重溪流域的歷史影像、斷面測量、河床質粒徑調查等資料。 * **現地地質查核**：對卑南溪及四重溪流域進行了地質露頭、崩塌地、土石流及河道現況的實地勘查，並記錄了相關數據。 * **地質詮釋與建置**：整合了收集到的資料，探討了地質構造對水系及地形發育的影響，並繪製了地質詮釋圖層，以供河川規劃參考。 * **系統維護、教育訓練與加值應用**：對流域地質資訊系統進行了更新與維護，舉辦了教育訓練，並以頭前溪流域為例，示範了如何利用遙測影像及既有資料庫進行河段穩定性評估。 計畫的最終目標是提供完整、更新的流域地質資訊，以協助水利署及其所屬機關進行河川規劃與整治工作。
