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.

本研究由經濟部水利署水利規劃試驗所主辦，國立交通大學執行，旨在進行中央管河川卑南溪及四重溪流域的地質資料查核與更新。計畫涵蓋基本資料蒐集、現地地質查核、地質詮釋與建置，以及流域地質資訊系統的維護更新、教育訓練與加值應用。 研究成果包含建置了卑南溪及四重溪流域的地質露頭、崩塌地、土石流及河道現況等資料，並進行地質詮釋，以了解地質條件對水系及地形發育的影響。同時，也更新了流域地質資訊系統，並舉辦教育訓練，推廣系統應用。此外，計畫還針對頭前溪流域的潛在沖刷河段進行了穩定性評估，並探討了網頁化系統互動功能的可能性。 本計畫的目標是提供水利署及其所屬機關參考，以利於河川規劃整治工作。
