UAV-SfM based field quantification of barchan dune celerity and morphodynamics in Gonghe Basin [PDF]

Barchan dunes do not often coexist with grasslands. However, in Gonghe Basin, north-eastern part in Qinghai-Tibetan Plateau (QTP), China, many barchan dunes are distributed on the grassland at high altitude.

CNN training of satellite images for "Detection and tracking barchan dunes using Artificial Intelligence"

This is part of the dataset concerning the YOLO training of satellite images (Barchan dunes). In this dataset, you find the "YOLOv8 train" folder that contains the structure and images obtained from HiRISE, CTX global mosaic, Google Earth Pro ...

Shape evolution of numerically obtained subaqueous barchan dunes

, 2020
In the realm of granular bedforms, barchan dunes are strong attractors that can be found in rivers, terrestrial deserts, and other planetary environments.

Wind-transport of barchan dunes in modulated gravity

, 2008
Barchan dunes can be found in sand barren regions under steady wind conditions. They translate in the direction of the wind while their shape remains unchanged.

Strong-wind events control barchan dune migration

Communications Earth & Environment
Wind is the most important external force in shaping aeolian landforms. Yet, it remains unclear what role the strong-wind events will play in the development of aeolian landforms compared with the effect of regular winds.

Barchan dunes: why they cannot be treated as 'solitons' or 'solitary waves'

, 2005
Schwämmle and Herrmann (Nature, 2003, vol. 426, p. 619) have suggested that two sub-aerial barchan sand dunes could 'pass through one another while still preserving their shape' in a manner similar to solitons or solitary waves. A wide range of published

Vegetation and induration as sand dunes stabilizators [PDF]

, 2008
Sand dunes are found in a variety of shapes in deserts and coasts and also on the planet Mars. The basic mechanisms of dune formation could be incorporated into a continuum saltation model, which successfully reproduced the shape of the barchan dunes and

Reproducing size distributions of swarms of barchan dunes on Mars and Earth using a mean-field model [PDF]

, 2022
We apply a mean-field model of interactions between migrating barchan dunes, the CAFE model, which includes spontaneous calving, aggregation, fragmentation, and mass-exchange, yielding a steady-state size distribution that can be resolved for different ...
