| 摘 要： | 针对渤海海域开展了波致底切应力对泥沙作用的数值估计。针对浅水条件,通过理想试验估算了波致底切应力对波流耦合底切应力的贡献。针对渤海大风过程,利用ECOMSED模式,通过波流耦合底边界层模型模拟了渤海区域的泥沙浓度,并利用遥感资料对表层泥沙浓度的数值模拟进行了检验。对比结果表明,考虑波浪作用的情况下,模拟结果在总体分布上得到明显的改善。在大风过程中波浪对0~20 m近岸区域的泥沙再悬浮起主导作用。

| Abstract: | The wave effect on sediment transport is analyzed in the Bohai Sea area. First, a series of ideal experiments were carried out to investigate the characteristics of wave-current coupled bottom shear stress and the proportion of wave-induced bottom shear stress. Second, a numerical simulation of suspended sediment concentration was compared with the remote sensing data during a gale process in the Bohai Sea. The results indicate that the model output is improved much when the wave-induced bottom shear stress is considered. The wave plays a key role in the resuspension of sediment in the shallow water of 0-20 m depth during the gale weather. |
