Measurements of the aeolian sand transport saturation length
B. Andreotti, P. Claudin, O. Pouliquen
The wavelength at which a dune pattern emerges from a flat sand bed is controlled by the sediment transport saturation length, which is the length needed for the sand flux to adapt…

Bedforms in a turbulent stream.Part 2: Formation of ripples by primary linear instability and of dunes by non-linear pattern coarsening
A. Fourrière, P. Claudin, B. Andreotti
It is widely accepted that both ripples and dunes form in rivers by primary linear instability, the wavelength of the former scaling on the grain size, that of the latter being con…
