The transport of sand and dust by wind is a potent erosional force, creates sand dunes and
ripples, and loads the atmosphere with suspended dust aerosols. This paper presents an …

For more than four decades remote sensing images have been used to document and
understand the evolution of aeolian sand dunes. Early studies focused on mapping and …

We introduce a novel agent‐based model for simulating interactions between migrating
barchan dunes. A new two‐flank representation of barchans allows modeling of bedform …

We investigate experimentally the short‐range interactions occurring between two
subaqueous barchans. The experiments were conducted in a water channel of transparent …

Sand dunes rarely occur in isolation, but usually form vast dune fields. The large scale
dynamics of these fields is hitherto poorly understood, not least due to the lack of longtime …

Barchan dunes are three‐dimensional, crescent‐shaped bedforms found in regions of
unidirectional flow and limited sediment supply, and while most commonly associated with …

Barchans are eolian dunes of crescent shape found on Earth, Mars and other celestial
bodies. Among the different types of barchan‐barchan interaction, there is one, known as …

We apply a mean-field model of interactions between migrating barchan dunes, the CAFE
model, which includes spontaneous calving, aggregation, fragmentation, and mass …

Three dimensional dunes of crescentic shape, called barchans, are commonly found on
Earth and other planetary environments. In the great majority of cases, barchans are …

Roughness elements of varied scale and geometry commonly appear on the surfaces of
sedimentary deposits in a wide range of planetary environments. They perturb the local fluid …
