控制淡水河河口輸沙的主要因素為潮汐、波浪、河川流量、河口地形及懸浮質及底床質特性等。為建立適用於淡水河口輸砂之理論模式，並提供淡水河河口漂沙及台北港漂沙之防治方法，本研究擬以三年為期，首先收集淡水河河口輸沙資料，並彙整及探討適用於淡水河口輸砂之理論；其次以實驗方式或現場資料檢定河口輸砂理論之適用性，並輔以現場資料調查，提出淡水河河口漂沙及台北港漂沙之防治方法。 The mechanisms controlling the sediment transport around Danshui river mouth and the surrounding coastalines are tides, waves, river flow, suspended load and bed load. In order to establish a mathematical tool to evaluate the suspension load and the stability of the Danshui river mouth, the proper evaluation of sediment transport in this region is required. In this study, we will explore the sediment transport process around Danshui river mouth in a three-year span. First, the hydraulic data is collected , and will be used to calibrate the suitable sediment transport equation. The model will be evaluated by either experimental or field studies. The goal of this study is to provide some alternatives to resolve the sediment erosion and accretion problems around Danshui river mouth and the Taipei Harbor. 研究期間：9505 ~ 9512
