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…
Comment on "Solving the mystery of booming sand dunes"
B. Andreotti, L. Bonneau, E. Clement
We show here that the standard physical model used by Vriend et al. to analyse seismograph data, namely a non-dispersive bulk propagation, does not apply to the surface layer of sa…
Integral method for flows down an incline: viscous, turbulent and granular cases
A. Fourrière, P. Claudin, B. Andreotti
The integral method can be used to model accurately flows down an inclined plane. Such a method consists in projecting the full 3D equations on a lower dimensional representation.…
Aeolian sans ripples: experimental study of saturated states
Bruno Andreotti, Philippe Claudin, Olivier Pouliquen
We report an experimental investigation of aeolian sand ripples, performed both in a wind tunnel and on stoss slopes of dunes. Starting from a flat bed, we can identify three regim…
Dynamic and instability of submarine avalanches
F. Malloggi, J. Lanuza, B. Andreotti +1
We perform a laboratory-scale experiment of submarine avalanches on a rough inclined plane. A sediment layer is prepared and thereafter tilted up to an angle lower than the spontan…
