Barchan-Parabolic Dune Pattern Transition From Vegetation Stability Threshold

, 2010
Many dune fields exhibit a downwind transition from forward-pointing barchan dunes to stabilized, backward-pointing parabolic dunes, accompanied by an increase in vegetation.

Morphodynamics of barchan and dome dunes under variable wind regimes

, 2018
International audienceDome dunes are traditionally interpreted as a transient or an independent class of bed-forms because of their rounded and smooth shape without slipfaces. Here we show that they can also reach a steady state and form dome dune fields,

A model of Barchan dunes including lateral shear stress

, 2005
Barchan dunes are found where sand availability is low and wind direction quite constant. The two dimensional shear stress of the wind field and the sand movement by saltation and avalanches over a barchan dune are simulated.

Morphodynamics of barchan and transverse dunes using a cellular automaton model

, 2010
International audienceWe analyze the morphodynamics of bedforms produced under unidirectional flow conditions by a lattice gas cellular automaton designed to study sediment transport.
