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 …

Based on four decades of research by Professor Andrew Goudie, this volume provides a
state-of-the-art synthesis of our understanding of desert geomorphology. It presents a truly …

The movement of active dunes is tightly linked to climatic conditions (eg, wind regime,
temperature and precipitation) as well as human influence (eg, grazing, dune fixation 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 …

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 …

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 …

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 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 …

In nature, barchan dunes typically exist as members of larger fields that display striking,
enigmatic structures that cannot be readily explained by examining the dynamics at the …
