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…
Limitations of empirical sediment transport formulas for shallow water and their consequences for swash zone modelling
Wei Li, Peng Hu, Thomas Pähtz +2
Volumetric sediment concentrations computed by phase-resolving swash morphodynamic models are shown to exceed unity minus porosity (i.e. the maximal physically possible concentrati…
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…
