摘要
针对钱塘江河口潮强流急,动力、泥沙含量变化复杂,建立了二维水流泥沙数学模型,模拟水流运动及含沙量变化,通过实测资料率定,模型较好地模拟了河口沿程水位、测点流速、含沙量过程以及断面输沙量,并对潮流泥沙特性和泥沙分布平面特征作了分析。
This paper presents a 2D numerical model of shallow flow that was developed to simulate the strong tidal flow and sediment transport in the Qiantang estuary,and was calibrated by using the measured data of the cross-sectional averages of water level,flow velocity and sediment concentration and the cross-sectional distribution of sediment transport load.An analysis of the tidal flow and sediment transport behaviors is also presented.
