The physics of sediment transport initiation, cessation, and entrainment across aeolian and fluvial environments
Thomas Pähtz, Abram H. Clark, Manousos Valyrakis +1
Predicting the morphodynamics of sedimentary landscapes due to fluvial and aeolian flows requires answering the following questions: Is the flow strong enough to initiate sediment…
Universal friction law at granular solid-gas transition explains scaling of sediment transport load with excess fluid shear stress
Thomas Pähtz, Orencio Durán
A key interest in geomorphology is to predict how the shear stress exerted by a turbulent flow of air or liquid onto an erodible sediment bed affects the transport load $M\tild…
Fluid forces or impacts: What governs the entrainment of soil particles in sediment transport mediated by a Newtonian fluid?
Thomas Pähtz, Orencio Durán
In steady sediment transport, sediment deposition is balanced by entrainment of bed particles by fluid forces or particle-bed impacts. Here we propose a proxy to determine the role…
The Cessation Threshold of Nonsuspended Sediment Transport Across Aeolian and Fluvial Environments
Thomas Pähtz, Orencio Durán
Using particle-scale simulations of non-suspended sediment transport for a large range of Newtonian fluids driving transport, including air and water, we determine the bulk transpo…
The fluctuation energy balance in non-suspended fluid-mediated particle transport
Thomas Pähtz, Orencio Durán, Tuan-Duc Ho +2
Here we compare two extreme regimes of non-suspended fluid-mediated particle transport, transport in light and heavy fluids ("saltation" and "bedload", respectively), regarding the…
Origins of barchan dune asymmetry: insights from numerical simulations
Eric J. R. Parteli, Orencio Durán, Mary C. Bourke +3
Barchan dunes --- crescent-shaped dunes that form in areas of unidirectional winds and low sand availability --- commonly display an asymmetric shape, with one limb extended downwi…
