In this study, the coherent structures formed in the wakes of barchan dunes are investigated using mea- surements of the flow over fixed-bed (i.e., solid) barchan models, both in the wake of an isolated barchan and the interdune region between interacting barchans (Fig. 1(a)).	cache/ispiv-79.pdf	txt/ispiv-79.txt
