Dunes form where winds blow over a bed of mobile sediment grains–conditions that are
common in our solar system. On Earth, dunes abound in arid continental interiors and along …

Wherever a loose bed of sand is subject to sufficiently strong winds, aeolian dunes form at
predictable wavelengths and growth rates. As dunes mature and coarsen, however, their …

We consider the possibility that aeolian (wind blown) processes occur on small, 1 to 100 km
diameter, planetesimals when they were embedded in the protosolar nebula. Drag from a …

Turbulent flows above a solid surface are characterised by a hydrodynamic roughness that
represents, for the far velocity field, the typical length scale at which momentum mixing …

Titan has a diverse range of materials in its atmosphere and on its surface: the simple
organics that reside in various phases (gas, liquid, and ice) and the solid complex refractory …

Loose sand, blown away from source regions by winds, is transported across Mars's surface
into sand sheets and dunes and accumulates within topographic sinks. In the absence of …

The Stimson formation is a late‐infilling eolian sandstone in Gale crater, Mars that formed
from sand accumulation in a dune field analogous to the modern active Bagnold dune field …

Bedforms emerge in a variety of shapes and sizes when a granular erodible surface is
subject to a strong enough shear flow, as observed in topographic data from submarine …

We use an established discrete element method (DEM) Reynolds-averaged Navier–Stokes
(RANS)-based numerical model to simulate non-suspended sediment transport across …

Nous passons en revue les principaux processus qui déterminent la morphodynamique des
dunes, c'est-à-dire leur croissance en hauteur, leur migration et leur élongation, et nous …
