长江口悬沙含量垂向分布数值模拟

Numerical simulation of vertical distribution of suspended sediment in the Yangtze River Estuary

根据长江口北槽和南槽实测的水沙资料,利用垂向一维悬沙数学模型模拟了长江口悬沙含量及其分布,并对摩阻流速和临底悬沙含量进行了简要分析.结果表明,计算值与实测值较为吻合.

Based on the measured data of the north-trough and south-trough in the Yangtze River Estuary, the vertical distribution of the suspended sediment concentration in the Yangtze River Estuary is simulated by using a one dimensional numerical model of the suspended sediment, and the friction velocity and close-to-bed suspended sediment concentration are briefly analyzed. Comparison results show that the calculated data have a pretty good coherence to the measured data.
