沙丘后混合层中的流动过程提供了水流、泥沙输移和床面形态之间的反馈，这被认为是沙丘发展和持续的原因。它是试图分类这些流动过程中的相干结构，其中上游边界层的涡量集中。流动显示的信息被用来描述这些旋涡结构。通过文献回顾，寻找类似流动情况下的理论和实验结果，这些结果可以提供基本的概念。
Flow processes in the mixing layer behind dunes provide the feedback between flow, sediment transport and the bed forms, which is assumed to be responsible for the development and persistence of dunes. It is attempted to classify these flow processes in terms of coherent structures, in which the vorticity of the upstream boundary layer is concentrated. Information from flow visualization is used to describe these vortical structures. The literature was reviewed to search for theoretical and experimental results of similar flow situations, which can provide the essential concepts.
