Size distribution and structure of Barchan dune fields [PDF]
Nonlinear Processes in Geophysics, 2011 Barchans are isolated mobile dunes often organized in large dune fields. Dune fields seem to present a characteristic dune size and spacing, which suggests a cooperative behavior based on dune interaction. In Duran et al.

Migration and Morphology of Asymmetric Barchans in the Central Hexi Corridor of Northwest China
Geosciences, 2018 Crescent-shaped barchan dunes often display an asymmetric shape, with one limb longer than the other. As shown in previous studies, asymmetric bimodal winds constitute one major cause of barchan asymmetry, but the heterogeneous conditions of sand ...

Exploring the transition between water- and wind-dominated landscapes in Deep Springs, California, as an analog for transitioning landscapes on Mars [PDF]
Earth Surface Dynamics, 2023 Many planetary surfaces have been shaped by eolian and fluvial processes, and understanding the resulting landscape is of critical importance to understanding changes in climate. Surface features on Earth and Mars are commonly observed using a variety of

How attractive is a barchan dune?
New Journal of Physics, 2009 The spatio-temporal behaviour of barchan dunes is investigated experimentally with downsized longitudinal barchan dune slices generated in a narrow water flow tube. The development towards a shape attractor is shown on the basis of four different starting configurations in qualitative observation and quantitative analysis.

Diachronic analysis to detect and monitor Barchan dune migration in Ain Salah (Algeria)
Geoadria, 2022 The aim of this work is to analyze deposit patterns and their effect on urban and agricultural areas in the Ain Salah region in southern Algeria. A supervised classification of Landsat images over a 13-year period (2005, 2009, 2013, and 2017) was applied

Binary collision of barchan dunes
, 2021 In nature, barchan dunes usually move in groups in most cases, and their sizes are roughly close to each other. A major cause of such stability is the binary collision among the dunes.
