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 …

Granular materials are ubiquitous in our daily lives. While they have been the subject of
intensive engineering research for centuries, in the last two decades granular matter has …

Untitled Page 1 Page 2 GEOMORPHOLOGY OF DESERT DUNES Sand dunes cover up to a
quarter of many desert regions. Determining the factors that determine their shape, size and …

Dunes are present in nearly all fluvial channels and are vital in predicting flow resistance,
sediment transport, and deposition within many rivers. Progress in understanding the fluid …

Aeolian processes involve the wind action on a sedimentary substrate, namely erosion,
sand transport and deposition. They are responsible for the emergence of aeolian dunes …

The present review summarizes experimental and theoretical work dealing with self-
organized solitary localized structures (LSs) that are observed in spatially extended …

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 …

Earth's surface is composed of a staggering diversity of particulate–fluid mixtures: dry to wet,
dilute to dense, colloidal to granular and attractive to repulsive particles. This material variety …

The linear stability analysis of the equations governing the evolution of a flat sand bed
submitted to a turbulent shear flow predicts that the wavelength λ at which the bed …

Field studies of barchans—crescent-shaped dunes that propagate over solid ground under
conditions of unidirectional wind—have long focused on the investigation of an equilibrium …
