Evolving dunes under flow reversals: from an initial heap toward an inverted dune
Willian Righi Assis, Erick de Moraes Franklin, Nathalie Vriend
Sand dunes are ubiquitous in nature, and are found in abundance on Earth and other planetary environments. One of the most common types are crescent-shaped dunes known as barchans,…
Strain hardening by sediment transport
Fernando David Cúñez Benalcázar, Erick de Moraes Franklin, Morgane Houssais +2
The critical fluid-shear stress for the onset of sediment transport, , varies with the history of applied shear. This effect has been attributed to compaction, but the role of…
Morphodynamics of barchan-barchan interactions investigated at the grain scale
Willian Righi Assis, Erick de Moraes Franklin
Corridors of size-selected crescent-shaped dunes, known as barchans, are commonly found in water, air, and other planetary environments. The growth of barchans results from the int…
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…
A comprehensive picture for binary interactions of subaqueous barchans
Willian Righi Assis, Erick de Moraes Franklin
We investigate experimentally the short-range interactions occurring between two subaqueous barchans. The experiments were conducted in a water channel of transparent material wher…
