采用MIKE21软件中的水动力模块与泥沙模块，对不同上游流量、不同泥沙中值粒径条件下的喇叭口型感潮河口的泥沙输移进行了数值模拟，并通过实测水文资料对数值模型进行了验算。结果表明：喇叭口型感潮河口的水位在丰水期和枯水期的变化规律基本一致，泥沙中值粒径对水位的影响很小，潮水位的影响起主导作用；淤积区域也基本一致，多集中于进口处和出口处，不同的是，丰水期冲刷区域位于河道两岸，呈条形分布，枯水期冲刷区域集中于进口与出口之间。

This paper used hydrodynamic module and sediment module of the MIKE21 software to conduct numerical simulation of the trump-et-shaped tidal estuary under different discharges of the upstream and different median diameters and verified the numerical model through ac-tually measured hydrologic data. The simulation results show that a trumpet-shaped tidal estuary basically has the same changing pattern in flood season and dry season;median diameter has very small influence on water level,the tidal levels plays a dominating role;the sedimenta-tion area is largely the same,centralizing in the inlet and outlet. The different point is that the eroding area in the flood season is on the two banks of the river,distributing in strips,while the eroding area in dry season is centralized on the middle section of the inlet and outlet.
