Numerical Simulation of Barchan-barchan repulsion
The dataset shared within these files consists of the full setup to perform a numerical simulation of a subaquous barchan-barchan dune interaction. The simulation was carried out using the open-source free CFDEM software, which couples the open-source ...

When Barchan Dunes Move Over Craters
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract We investigate the possible outcomes of a subaqueous barchan moving over a crater‐like depression in the bed. For that, we carried out experiments where we varied the dune size, crater and grain diameters, and flow velocities. We found that subaqueous barchans can be blocked, destroyed, or pass over craters, with transitional situations, and ...

Transient Hydrology in Amazonis Planitia (Mars) in the Aftermath of the Tooting Impact
Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.Abstract Hydrological flows generated by meteoroid impact are still largely unexplored on Mars and may also have implications for Earth. We reconstructed the hydrological sequence initiated on Mars by a less than 3 Ma old meteoroid impact that formed the 28 km‐wide Tooting crater on Amazonis Planitia, an ice‐bearing region.

The morphology of barchan-shaped sand banks from western Torres Strait, northern Australia
, 2007 Large barchan-shaped sand deposits have been observed in the north west of Torres Strait. These deposits share characteristics of both subaerial barchan dunes and subaqueous sand banks.

Groundwater Altered Water Balance and Plant Water Use Efficiency in Desert Ecosystems
Water Resources Research, Volume 61, Issue 11, November 2025.Abstract Groundwater is an important water source in water‐limited desert ecosystem. Less attention has been paid to how the water balance and plant performance in such ecosystems vary with the presence or absence of groundwater. Appropriate replanting strategies play a pivotal role in preventing desertification.

The flow structure of interacting barchan dunes [PDF]
, 2010 High-resolution particle-image velocimetry (PIV) experiments have been conducted over a fixed-bed to examine the effects of interacting barchan dunes on the flow structure.

Slowdown of Dune Migration in East Asia's Inland Deserts: A 35‐Year Response to Wind Stilling
Geophysical Research LettersGlobal terrestrial stilling, the recent decrease in near‐surface wind speeds, has significant environmental impacts, including reduced dust storms and vegetation recovery in East Asia's drylands. However, direct evidence of stilling effects on sand dunes
