Remote Sensing, 2019 A barchan dune near Tarfaya in Morocco has been surveyed using ground-penetrating radar (GPR) revealing packages of dipping strata within the dune that are truncated by bounding surfaces. The bounding surfaces dip in the downwind direction, truncate sets

The evolution of snow bedforms in the Colorado Front Range and the processes that shape them [PDF]
The Cryosphere, 2019 When wind blows over dry snow, the snow surface self-organizes into bedforms such as dunes, ripples, snow waves, and sastrugi. These bedforms govern the interaction between wind, heat, and the snowpack, but thus far they have attracted few scientific ...

Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract Transverse aeolian ridges (TARs) on Mars exhibit distinct characteristics relative to other aeolian features, yet their formation and evolutionary mechanisms remain unclear. A comprehensive investigation of TAR's distribution, morphology, composition, and environmental influences is critical for advancing our understanding of their development

On the genesis and evolution of barchan dunes: morphodynamics
, 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 ...

High-precision remote sensing mapping of aeolian sand landforms based on deep learning algorithms
Open Geosciences, 2022 It is significant to adopt deep learning algorithms and higher-resolution remote sensing images in mapping large-scale and high-precision of aeolian landform. In this study, the western part of Horqin Sandy Land was taken as the study area.

Terrestrial Analogs to Titan for Geophysical Research
Reviews of Geophysics, Volume 64, Issue 2, June 2026.Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Sedimentology, Volume 73, Issue 3, Page 620-644, April 2026.ABSTRACT The Gollum Channel System is a land‐detached large‐scale canyon‐channel system situated offshore southwest Ireland on the Northeast Atlantic margin. The system has been considered inactive with downslope gravity flows since the last glacial period, but geophysical data in some of its branches do suggest Holocene activity.

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.
