Quantifying the form-flow-saltation dynamics of aeolian sand ripples
J. M. Nield, M. C. Baddock, G. F. S. Wiggs +9
Ripples are the most fundamental and ubiquitous aeolian bedforms formed on sandy surfaces, but their small size and fast response times make them inherently difficult to measure. H…

Aerodynamic roughness of rippled beds under active saltation at Earth-to-Mars atmospheric pressures
C. A. Alvarez, M. G. A. Lapôtre, C. Swann +3
As winds blow over sand, grains are mobilized and reorganized into bedforms such as ripples and dunes. In turn, sand transport and bedforms affect the winds themselves. These compl…

Modeling the dynamics of aeolian meter-scale bedforms induced by bed heterogeneities
C. Rambert, J. M. Nield, C. Narteau +6
Desert surfaces are typically non uniform, with individual sand dunes generally surrounded by gravel or non-erodible beds. Similarly, beaches vary in composition and moisture that…
