Morphodynamics, Genesis, and Anthropogenically Modulated Evolution of the Elfeija Continental Dune Field, Arid Southeastern Morocco

open access: yesEarth
The Elfeija Dune Field (EDF) is a continental aeolian system in an arid region of southeastern Morocco. Studying this system is critical for understanding the effects of mounting climatic and anthropogenic pressures.

Morphogenese et Dynamique des Barchanes

open access: yes, 2004
Lyderic Bocquet, Tomas Bohr, François Charru, Eric Clément et Francois MétivierBarchans 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

Shape of barchan dunes as an indicator of wind regime: a case study from the Moroccan Western Sahara

open access: yes, 2012
Barchans are characterized by a symmetric shape independently of their stage of development and the axis of symmetry parallels to the dominant wind direction. However, shape of the dunes can be modified by several factors, among which most important are:

On the genesis and evolution of barchan dunes: morphodynamics

open access: yes, 2017
Barchan dunes are crescent-shaped formations of sand that can dominate both desert and subaqueous landscapes when the supply of sand is scarce. Because of the complexity and scale of the underlying phenomena, the mechanisms governing the entire process ...

Evolving Dunes Under Flow Reversals: From an Initial Heap Toward an Inverted Dune

open access: yes
Sand dunes are ubiquitous in nature, and are found in abundance on Earth and other planetary environments. One of the most common types are crescent‐shaped dunes known as barchans, whose mid‐line could be assumed to behave as 2D dunes.

Barchan morphometry: examples from Earth and Mars

open access: yes, 2019
Electronic Thesis or DissertationBarchans are a common sand dune type found on both terrestrial and Martian surfaces. The morphometry of individual barchans and barchan groups has been measured extensively in past studies. Within each dune field, similar

Characterization of barchanoid dune systems on the Cap Ferret spit (Aquitaine)

open access: yes
International audienceThe Cap Ferret spit (Atlantic coast, France) is defined by barchanoid dune systems formed by a large input of sand remobilized by aeolian dynamics.
