本年度將以花蓮溪、急水溪及朴子溪流域為計畫範圍，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 (2004-2012) projects. During 2004-2012, field verification was carried out in 19 river basins (including the Lanyang, Fongshan, Touchien, Jhonggan, Houlong, Da-an, Dajia, Wu, Jhuoshuei, Beigang, Bazhang, Zengwun, Yanshui, Erren, Agongdian, Gaoping, Donggang, 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 2013 project covered (1) the collection of new data, (2) the field verification of the Hualien, Jishui, and Puzi River basins, (3) the maintenance of GGIS and its user interfaces, and (4) training courses. The total numbers of verification sites of the basin verified in Hualien, Jishui, and Puzi River basins are 383, which include 56 rock outcrops and geologic structures, 276 sites of riverbed conditions, 12 of geo-hazards, and 33 sites of geologic interpretation. The verification results were compiled and built into the GGIS system.

這份由經濟部水利署水利規劃試驗所與國立交通大學於2013年發布的報告，旨在查核花蓮溪、急水溪及朴子溪流域的地質資料，並將其整合至河川流域地質資訊系統(GGIS)。 計畫透過資料蒐集、正射影像判釋及現地查核，記錄了大量地質露頭、崩塌地、土石流潛勢區及河道現況。報告深入詮釋各流域的地形發育、河道變遷及沖淤狀況，揭示花蓮溪受板塊碰撞影響，地殼抬升劇烈，易有河川襲奪及大規模崩滑；急水溪與朴子溪則受斷層控制，上游侵蝕、下游堆積顯著。這些地質詮釋為河川規劃整治提供重要參考，同時也維護更新了GGIS系統並舉辦教育訓練。
