| 摘 要： | 以含沙水流为研究对象,采用一般曲线坐标系下平面二维水沙输移数学模型对长江武汉河段岸边高浓度泥浆排放所形成的浓度场进行了数值模拟.模型重点考虑了高浓度泥浆在输移扩散过程中与河床的交换以及泥沙级配、河床变形对水沙运动的影响,计算结果能为工程单位决策提供科学依据. |
| 关 键 词： | 输移扩散 一般曲线坐标 水沙数学模型 河床变形 |

| Abstract: | An unsteady two-dimension(2-D) horizontal mathematical model for flow and sediment in generalized curvilinear coordinate is employed to simulate the contaminated zone induced by side-discharged dense slurry in Wuhan reach of the Yangtze River.The exchange between suspended silt and riverbed,sand graduation and riverbed deformation are taken into account in the model.The results can give reliable and scientific base for engineering organization to make a decision. |
| Keywords: | disperse and transport generalized curvilinear coordinate model for water flow sediment riverbed deformation |
