Sand dunes as migrating strings

open access: yesPhysical Review E, 2013
We develop a reduced complexity model for three-dimensional sand dunes, based on a simplified description of the longitudinal and lateral sand transport. The spatiotemporal evolution of a dune migrating over a nonerodible bed under unidirectional wind is reduced to the dynamics of its crest line, providing a simple framework for the investigation of ...

Fine dust emissions from active sands at coastal Oceano Dunes, California [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
Sand dunes and other active sands generally have a low content of fine grains and, therefore, are not considered to be major dust sources in current climate models.
