| 中文摘要: |
| 本文建立了剖面二维水流泥沙数学模型。采用贴体坐标及有限差分方法，用流函数-涡量为变量的零方程率流模型求解流速场。对横向槽沟内泥沙淤积与水平轴环流进行了数值模拟，并分析了槽沟内泥沙淤积与水平轴环流变化的关系。 |
| 英文摘要: |
| A 2-D flow-sediment mathematical model is established.The flow field is calculated by using zero-equation turbulence model with boundary-fitted coordinate system.The concentration field of suspended sedimentis calculated by using diffusion equation.The sediment deposition and the horizontal axis circulation flow are simulated and their relationship is also analyzed. |
