Detection and tracking of barchan dunes using artificial intelligence [PDF]
Scientific ReportsBarchans are crescent-shape dunes ubiquitous on Earth and other celestial bodies, which are organized in barchan fields where they interact with each other.

Dataset of turbulent flow over interacting barchan dunes [PDF]
Data in BriefBarchans are dunes commonly found in dune fields on Earth, Mars and other celestial bodies, where they can interact with each other. This article concerns experimental data for the flow over subaqueous barchans that are either isolated or interacting ...

Migration and Morphology of Asymmetric Barchans in the Central Hexi Corridor of Northwest China
Geosciences (Switzerland), 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 ...

Barchan Dunes Cruising Dune‐Size Obstacles
Geophysical Research Letters, 2023 We investigate the behavior of subaqueous barchans reaching dune‐size obstacles by carrying out experiments where we varied the obstacle shape and size, the flow strength, and the grains' properties.

The genetic diversity of the genus Mus (Linnaeus, 1758) in the eastern part of the North Caucasus [PDF]
BMC Zoology, 2021 Background There are two species of Mus in the Caucasus: M. musculus and M. macedonicus. M. musculus is widespread in the Caucasus, where the species is found everywhere from the Black to the Caspian Sea. M. macedonicus is ubiquitous Transcaucasia.

Vegetation covers change and its impact on Barchan Dune morphology in Parangtritis Coast, Indonesia [PDF]
E3S Web of Conferences, 2020 Barchan dune is a peculiar type of dune that forms in wind corridors at the Inner Zone of Parangtritis Sand Dune. Their existence is increasingly threatened by land-use changes, especially vegetation coverage.

Morphodynamics of Barchan‐Barchan Interactions Investigated at the Grain Scale [PDF]
Journal of Geophysical Research: Earth Surface, 2021 Abstract Corridors of size‐selected crescent‐shaped dunes, known as barchans, are commonly found in water, air, and other planetary environments. The growth of barchans results from the interplay between a fluid flow and a granular bed, but their size regulation involves intricate exchanges between different ...

Linear Dunes: Morphology from Google Earth [PDF]
Desert, 2023 Linear dunes are widespread in the Earth’s deserts and also in some extraterrestrial locations such as Titan and Mars. They show great variety in their forms, and occur in three main classes: simple, compound and complex.

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
