以歷年查核及建立的流域地質資訊系統為基礎，週期性現地複查系統內26條流域河道狀況、土石災害並更新地質鑽探、正射影像、斷面資料、河床質粒徑…等成果，持續性納入新蒐集之圖資並補充地質詮釋資料，另外，並進一步加值應用平台資訊，如軟岩質河段沖刷潛勢評估、易致災河段邊坡岩性組成資料調查評估等。

A geological Geographic Information System (GGIS) for the river basins administered by the Water Resource Agency was established and periodically updated in the previous (2004-2014) projects. During 2004-2014, field verification was conducted 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. User interfaces for GGIS were also developed to enhance user friendliness. The main task for this project is to recheck the current status of the Da-an, Dajia, Wu, Jhuoshuei and Bazhang basins. New data set were compiled and built into the GGIS system after field check. The new data set include 21 sites of landslide and 36 sites of riverbed conditions. In addition, five case studies were presented to demonstrate how to use the data base in the GGIS for the purpose of site-investigation planning or for the evaluation of geological influence. Two training courses were held at the end of this project. This first one covers the geological law, the geo-sensitive zones in Taiwan and the GGIS. The second course covers a few case studies for the geological evaluation of geo-sensitive zones and the usage of UAV (Unmanned Aerial Vehicle) in constructing DSM (Digital Surface Model). The training courses help to prompt the application of the GGIS for the engineers in river management and water resource planning.

本報告由經濟部水利署水利規劃試驗所委託國立交通大學執行，旨在維護更新並應用「流域地質資訊系統」。計畫內容包含基本圖資更新、週期性現地複查中央管河川流域（大安溪、大甲溪、烏溪、濁水溪、八掌溪），並探討河道穩定性案例，如和社堰塞湖再發生性、固床工河道穩定性、堤防設計參數評估等。同時，報告也詳述了系統的維護、資料建置、平台更新與推廣使用，並包含教育訓練。透過此系統，可提供地質資訊，協助水利規劃與災害防治。
