Barchan-barchan and barchan-obstacle interactions: insights from grain-scale studies
Erick de Moraes Franklin, Willian Righi Assis, Danilo da Silva Borges +1
Sand dunes are bedforms that grow due to the action of a fluid flow over a sand bed or pile. Whenever the fluid flow is mainly in one direction and the availability of sand is limi…

Barchans interacting with dune-size obstacles: details of the fluid flow and motion of grains
Nicolao Cerqueira Lima, Willian Righi Assis, Danilo da Silva Borges +1
We investigate details of the interaction of subaqueous barchans with dune-size obstacles by carrying out numerical simulations where the fluid is solved at the grain scale and the…
