| 摘要: |
| 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。 |

| Abstract: |
| 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. |
