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…
Megaripple mechanics: bimodal transport ingrained in bimodal sands
Katharina Tholen, Thomas Pähtz, Hezi Yizhaq +2
Aeolian sand transport is a major process shaping landscapes on Earth and on diverse celestial bodies. Conditions favoring bimodal sand transport, with fine-grain saltation driving…
Unified model of sediment transport threshold and rate across weak and intense subaqueous bedload, windblown sand, and windblown snow
Thomas Pähtz, Yonghui Liu, Yuezhang Xia +3
Nonsuspended sediment transport (NST) refers to the sediment transport regime in which the flow turbulence is unable to support the weight of transported grains. It occurs in fluvi…
