本年度將以秀姑巒溪及和平溪流域為計畫範圍，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 (2004-2013) projects. During 2004-2013, field verification was carried out in 24 river basins (including the Lanyang, Fongshan, Touchien, Jhonggan, Houlong, Da-an, Dajia, Wu, Jhuoshuei, Beigang, Puzi, Bazhang, Jishui,Zengwun, Yanshui, Erren, Agongdian, Gaoping, Donggang, Hualien,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 2014 project covered (1) the collection of new data, (2) the field verification of the Xiuguluan and Heping basins, (3) the maintenance of GGIS and its user interfaces, (4) the implementation of Web-GIS and (5) training courses.The total numbers of verification sites of the basin verified in Xiuguluan and Heping River basins are 169, which include 34 rock outcrops and geologic structures, 91 sites of riverbed conditions, 24 of geo-hazards, and 20 sites of geologic interpretation. The verification results were compiled and built into the GGIS system.

本報告由經濟部水利署水利規劃試驗所與國立交通大學於2014年完成，延續河川流域地質資訊系統(GGIS)建置計畫。主要針對秀姑巒溪及和平溪流域進行地質查核與資料詮釋，並將成果納入GGIS。 計畫蒐集更新地質圖資，並現地查核地質露頭、崩塌地、土石流及河道現況共169筆。報告深入探討兩流域的地形發育、河道變遷及沖淤變化，繪製地質剖面圖。秀姑巒溪因河流襲奪形成獨特地形，和平溪則受地殼抬升影響。 本計畫亦維護GGIS系統，開發網頁化查詢平台，並舉辦教育訓練，旨在提供河川規劃整治的重要地質參考資訊。
