On the testing of grain shape corrections to bedload transport equations with grain-resolved numerical simulations
Yulan Chen, Orencio Durán, Thomas Pähtz
Using grain-resolved LES-DEM simulations, Zhang et al. (J. Geophys. Res. Earth Surf. 130, e2024JF007937, 2025) aimed to validate a grain-shape-corrected bedload transport equation…
Emergence of wind ripples controlled by mechanics of grain-bed impacts
C. W. Lester, A. B. Murray, Orencio Duran +2
Periodic sediment patterns have been observed on Earth in riverbeds and sand and snow deserts, but also in other planetary environments. One of the most ubiquitous patterns, famili…
Coevolving aerodynamic and impact ripples on Earth
Hezi Yizhaq, Katharina Tholen, Lior Saban +11
Windblown sand creates multiscale bedforms on Earth, Mars, and other planetary bodies. According to conventional wisdom, decameter-scale dunes and decimeter-scale ripples emerge vi…
Addressing bedload flux variability due to grain shape effects and experimental channel geometry
Thomas Pähtz, Yulan Chen, Jiafeng Xie +8
The study-to-study variability of bedload flux measurements in turbulent sediment transport borders an order of magnitude, even for idealized laboratory conditions. This uncertaint…
Scaling laws for planetary sediment transport from DEM-RANS numerical simulations
Thomas Pähtz, Orencio Duŕan
We use an established discrete element method (DEM) Reynolds-averaged Navier--Stokes (RANS)-based numerical model to simulate non-suspended sediment transport across conditions enc…
