| 摘 要： | 针对窄深的潮汐河口建立了沿宽度方向积分平均的垂向二维悬沙输移数学模型,潮流场的模拟采用三维MOHID模型,悬沙对流扩散方程采用Galerkin有限元法进行求解。利用该模型模拟了长江口北槽段潮流输沙过程,计算结果与实测资料较好吻合,表明了该模型能够模拟窄深的潮汐型河口地区悬沙输移过程。

| Abstract: | A laterally-averaged 2-D vertical mathematical model is presented for the suspended sediment transport in the tidal estuary using Galerkin finite element method.The tide field is simulated by the 3-D MOHID model and the convection-diffusion equation is discreted by using Galerkin finite element method.This model is adopted to simulate the suspended sediment transport at the north passage of Changjiang River Estuary and the calculated results coincide with the field data,which validates this model can simulate the suspended sediment transport process in the tidal estuary. |
