Horns of subaqueous barchan dunes: A study at the grain scale
Horns of subaqueous barchan dunes: A study at the grain scale
Many complex aspects are involved in the morphodynamics of crescent-shaped dunes, known as barchans. One of them concerns the trajectories of individual grains over the dune, and how they affect its shape. In the case of subaqueous barchans, we proposed in Alvarez and Franklin [Phys. Rev. Lett. 121, 164503 (2018)] …
