水利署第八河川局(以下稱本局)歷年辦理河川水文量測，限於人力及安全考量，高流量情況下之觀測有其困難。實際操作過程中，因天候不佳，視線不良，人員安全考量或橋梁封閉的情況下，難以實施全日人工觀測。加上受限於人力及設備，單次人工觀測的時間通常為2小時以上，每日能作業時間及得到的數據組數很少，難以充份掌握整個洪水流量變化過程，對於預警及事後檢討幫助有限。 自動化水文量測系統具有不受天候、視線、封橋、人員安全及疲睏問題等影響，所能量測資料之數量及品質優於人工方式，故建置自動化儀器為未來水文測驗工作發展之趨勢。 爰此，本計畫於本局所轄台東大橋水位流量站辦理固定式自動化水文觀測作業，進行水深、濁度、表面流速、河床沖刷量測及閉路電視(CCTV)回傳現場影像等工作，並使其於高流量下具自動化量測功能，冀能提高水文量測之能力及品質。 同時將固定式之概念整合水文觀測儀器於本局既有之水文工作車上，使其具備高度自動化之特性，達到「單人即可完成河川水文量測」之理想（基於安全理由，出外作業時仍以至少兩人為一組進行）。

The 8th River Management Office has difficulty to measure high flow discharge due to limitation of manpower, safety, bad weather, poor visibility and bridge closure. In real situation, it takes at least 2 hours to complete single manual observation, resulting in very few data collected during one typhoon period. The automated hydrology observation system had advantage of not affected to the above problems, and the data quality is better than manual observation. Therefore, establishing automatic sensoring system is a future trend. The project install a stationary automated hydrology observation system at the Tai-tung Bridge to measure flow depth, turbidity, surface velocity, bed erosion during high flow discharge, and the system can deliver live video back to the control center with a CCTV. Another toget is to use the concept of stationary automated hydrology observation system to integrate instruments on a car; it is highly automated and mobile and achieves a goal of "one person can complete the measurement of river hydrology". (However, for security reasons, the field work still needs at least two people to complete).
