导出了风浪和潮流共同作用下的悬沙输移方程式和扶沙能力公式,建立了河口海岸平面二维泥沙数学模型。验证表明,此模型可以较好地模拟风浪和潮流作用下河口海岸区含沙量分布场和海底冲淤变化,为研究和解决河口海岸工程中的泥沙问题提供了新手段。
The equations of suspended sediment transport and sediment carrying capacity under the combined action of wind wave and tidal current are derived, and the mathematical model of two-dimensional sediment in estuary and coast is established. The results show that this model can simulate the changes of sediment distribution and seabed sediment changes in the estuarine and coastal waters under the influence of storms and tidal currents, which provides a new method for studying and solving sediment problems in estuarine and coastal areas.
