Grain-scale computations of barchan dunes
Nicolao Cerqueira Lima, Willian Righi Assis, Carlos Azael Alvarez +1
Barchans are crescent-shaped dunes commonly found in diverse environments and scales: from the 10-cm-long barchans found under water to the 1-km-long barchans on Mars, passing by t…
Growth of barchan dunes of bidispersed granular mixtures
Carlos Azael Alvarez Zambrano, Fernando David Cúñez Benalcázar, Erick de Moraes Franklin
Barchans are dunes of crescentic shape found on Earth, Mars and other celestial bodies, growing usually on polydisperse granular beds. In this Letter, we investigate experimentally…
Force distribution within a barchan dune
Carlos Azael Alvarez Zambrano, Erick de Moraes Franklin
Barchan dunes, or simply barchans, are crescent-shaped dunes found in diverse environments such as the bottom of rivers, Earth's deserts and the surface of Mars. In a recent paper…
Horns of subaqueous barchan dunes: A study at the grain scale
Carlos Azael Alvarez, Erick de Moraes Franklin
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 h…
Shape evolution of numerically obtained subaqueous barchan dunes
Carlos Azael Alvarez Zambrano, Erick de Moraes Franklin
In the realm of granular bedforms, barchan dunes are strong attractors that can be found in rivers, terrestrial deserts and other planetary environments. These bedforms are charact…
Role of transverse displacements in the formation of subaqueous barchan dunes
Erick M. Franklin, Carlos A. Alvarez
Crescentic shape dunes, known as barchan dunes, are formed by the action of a fluid flow on a granular bed. These bedforms are common in many environments, existing under water or…
