基於整合型研究計畫目標，本研究計畫以全流域觀點為目標，建立中上游河川至河口水動力及輸沙機制之自動化量測系統以及相關河道水理演算。透過研究標的河川水文及底質資料，分析國內外河川水動力與輸沙傳輸經驗公式，進行河川懸浮質及底質採樣率定輸沙公式的性用性及開發可用於颱洪期間河渠量測技術方法；以質點追蹤進行全流域現地河川流量量測及量測技術驗證術，特別是在洪氾期間河川流速量測及輸砂量推估，發展及率定河川水動力及輸沙模式；分析全流域水動力及相關地形變化耦合模式。
Based on the objectives of the integrated research project, this study aims to establish an automated measurement system of hydrodynamic and sediment transport mechanisms in the middle and upper reaches of the river to the estuary and the hydrological calculation of related river basins. Through the study of the target hydrological and sediment information of the river, the domestic and international empirical formulas of river hydrodynamic and sediment transport are analyzed, and the usability of the sediment transport formula of suspended sediment and sediment sampling in the river is developed. The PT is then used to conduct in-situ river flow measurement and measurement verification in the whole basin, especially river flow rate measurement and sand production estimation during the flood season, to develop and rate the river hydrodynamic and sediment transport modes. Finally, the coupling model of hydrodynamic and related terrain changes in the whole basin is analyzed.
