Surface airflow patterns at a barchan dune field in Hellespontus Montes, Mars [PDF]

Mobile barchan dunes are well-developed in a crater in the Hellespontus Montes region on Mars. Previous studies of their temporal evolution show that the barchans maintain their shape and migrate in a uniform pattern.

A Preliminary Study on Variation in Wind Velocity and Sediment Transport Rate on Windward Slope of Barchan Dune

Shuitu baochi yanjiu, 2006
Field measurement of surface wind velocity and sediment transport rates was made on barchan dune in Wulanbuhe desert to understand.The results show that the wind velocities increasing upon windward slopes of the dunes vary with both slope morphology and ...

Hydrodynamic significance of variable ripple morphology across deep-water barchan dunes in the Faroe-Shetland Channel

, 2002
A combination of high-resolution (30 kHz) sidescan sonar and seafloor photography has been used to image barchan dunes and sand ripples in the Faroe-Shetland Channel.

Satellite remote sensing and field analyses of megaripples and dunes in the Skeleton Coast National Park, Namibia

Science of Remote Sensing
The morphology of aeolian bedforms is controlled by the boundary conditions during their formation and evolution, playing a crucial role in reconstructing current and past environmental settings.
