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 …

Abstract Knowledge of wind erosion as a dynamic phenomenon changing in space is of
importance in measuring and modeling soil erosion. While, many erosion studies have been …

Aeolian ripples are common in sandy environments on Earth and Mars. On Earth, ripples in
sorted dune sands typically are< 1 cm high and are erased in high winds. On Mars in similar …

Laboratory experiments indicate that the fluid threshold friction speed, u* tf, required to
initiate fully developed aeolian saltation is much higher on Mars than on Earth. A …

Sand bed length is an important parameter that affects soil wind erosion. Although there has
been a series of studies about the effect of sand bed length on wind erosion rate, many …

The surface of Pluto is more geologically diverse and dynamic than had been expected, but
the role of its tenuous atmosphere in sha** the landscape remains unclear. We describe …

Abstract The Mars Science Laboratory rover Curiosity visited two active wind‐blown sand
dunes within Gale crater, Mars, which provided the first ground‐based opportunity to …

Subaqueous and aeolian bedforms are ubiquitous on Earth and other planetary
environments. However, it is still unclear which hydrodynamic mechanisms lead to the …

One of the physically least understood characteristics of geophysical transport of sediments
along sediment surfaces is the well-known experimental observation that the sediment …

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 …
