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 …

Nature-based solutions to mitigate the impact of future climate change depend on restoring
biological diversity and natural processes. Coastal foredunes represent the most important …

Barchan dunes—crescent-shaped dunes that form in areas of unidirectional winds and low
sand availability—commonly display an asymmetric shape, with one limb extended …

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 …

The physics of dunes relies on the interaction between a wind flow and an erodible
topography. Thus, if strong enough to transport grains, the wind shapes sandy areas into …

The present work examines the temporal evolution of dune number density in desert
barchan dune fields and the effects of wind velocity, particle diameter and sand supply …

The Precambrian is associated with a set of geologically unique palaeoenvironmental
conditions arising from differences in the Earth's atmosphere, biosphere and geosphere …

Sand dunes are ubiquitous in deserts, on coasts, on the sea bottom, and on the surface of
Mars, Venus and Titan. The quantitative understanding of dune dynamics is thus of …

Barchan dunes migrate in swarms, with rich but not fully revealed self-stabilization
mechanisms. The interaction between dunes is considered as one of the key reasons for …
