Morphogenesis and Dynamics of Barchan Dunes

, 2004
Barchans are crescentic and mobile dunes which develop on a firm ground under a (roughly) mono directionnal wind. Since the Pioneering work of R. A. Bagnold, many studies have been performed; directly on the field or with the help of numerical models. However, barchans have a very striking property : no barchans smaller than, typically ten meters wide ...

Global barchans: A distributional analysis

Aeolian Research, 2020
Abstract Analysis of Google Earth imagery shows that barchans have an uneven global distribution. Nevertheless, they are widespread, and found in many of the world’s deserts, as well as from some moist coastal areas. Most barchans occur in 11 main provinces, and some of these are great in extent and contain large numbers of individual dunes.

Barchans of Minqin: Morphometry

Geomorphology, 2007
The barchans on the border of Minqin oasis, China, were surveyed. Our data reconfirmed that the height of slipface is proportional to the width of horns and the baseline can be roughly described by parts of an ellipse and a parabola. We attempted to study dune geomorphology using the theory of differential geometry.
