On the effect of two-direction seasonal flows on barchans and the origin of occluded dunes
Willian Righi Assis, Danilo da Silva Borges, Erick de Moraes Franklin
We inquire into the morphodynamics of barchans under seasonal flows. For that, we carried out grain-scale numerical computations of a subaqueous barchan exposed to two-directional…
