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…
Resultant force on grains of a real sand dune: How to measure it?
Renato F. Miotto, Carlos A. Alvarez, Danilo S. Borges +2
Dunes are bedforms found on sandy terrains shaped by fluid flow on Earth, Mars, and other celestial bodies. Despite their prevalence, understanding dune dynamics at the grain scale…
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…
Detection and tracking of barchan dunes using Artificial Intelligence
Esteban Andrés Cúñez Benalcázar, Erick de Moraes Franklin
Barchans are crescent-shape dunes ubiquitous on Earth and other celestial bodies, which are organized in barchan fields where they interact with each other. Over the last decades,…
Barchan dunes cruising dune-size obstacles
Willian Righi Assis, Danilo da Silva Borges, Erick de Moraes Franklin
We investigate the behavior of subaqueous barchans reaching dune-size obstacles by carrying out experiments where we varied the obstacle shape and size, the flow strength, and the…
