| 摘 要： | 本文针对黄河三角洲海岸潮间带广阔、黄河入海水沙变化剧烈、近岸及河口区水动力条件复杂的特点 ,建立了 1个潮流作用下的平面二维动边界全沙数学模型。动边界的处理采用窄缝法 ,并利用此模型对黄河三角洲洪、枯季时悬沙分布以及底床的冲淤进行了数值模拟 ,进而据此探讨了黄河三角洲洪、枯季的冲淤变化规律。

| Abstract: | In this paper, a H2DMB NSM (Horizontal Two-Dimensional Moving-Boundary Numerical Sediment Model) is developed, which takes into consideration of the characteristics of the tidal land of the Huanghe Delta, such as its extensive stretch, radical changes in water discharge and sediment infusion and complex dynamics. The slot method is used to deal with the moving boundary. The suspended sediment distribution in the supposed estuaries and the bottom erosion and deposition are simulated. The result shows that the model is generally effective.= |
