中文摘要：
长江下游大通以下河道宽阔、支汉众多，同时受径流、潮流双重作用，水沙运动非恒定性强．基于以上特点，建立了长江下游大通至徐六径具有河网特点的一维非恒定流悬沙数学模型．经验证，模型能够反映径流、潮流双重来流、来沙条件下本河段内的冲淤．
英文摘要：
In the estuary reach of the Yangtze River downstream of Datong Station, the river channel is multi- branched and broad, and the flow and sediment transportation is unsteady under the interaction of runoff and tidal current. According to its characteristics, a 1-D unsteady mathematical model for suspended sediment with the channel network character is proposed to simulate the process of flow and sediment transportation in the reach from Datong to Xuliujing. Validation of the model shows that the model can simulate the scour and silting in the reach under the interaction of runoff and tidal current.
