摘要
采集长江口潮滩的天然沙,利用华东师范大学河口海岸学国家重点实验室的波、流水槽,进行了波浪作用下悬沙垂向扩散特性的实验研究.根据实验数据,分别获得规则波和随机波作用下悬沙浓度垂线分布,并确定了在不同波浪作用条件下的悬沙垂向扩散系数以及其它垂向分布.
Experiments on sediment mixing characteristics under waves were carried out by using of a wave-flow-sediment flume. From experimental data, the vertical distributions of suspended sediment concentration （SSC） and vertical sediment mixing coefficients were determined under regular and irregular waves, respectively. It is found from experimental results that the vertical distribution of SSC agrees well with natural logarithm and the vertical sediment mixing coefficient may be described as εy = C1 e^D1 Y.
