Evaluation of threshold-based models to account for surface moisture in meso-scale aeolian sediment transport simulations
(2023) p.670-683- Abstract
- Aeolian transport rates decreases during wet conditions as the threshold shear velocity for initiation of transport increases over moist sand. This study investigates the influence of surface moisture on meso-scale aeolian transport simulations. Yearly transport rates towards the dunes are simulated with ten different threshold-based models to account for moisture effects. The ten models show large variability when comparing the wet threshold shear velocities for a range of surface moisture conditions. However, for yearly simulations of aeolian transport towards the dunes, all models resulted in similar transport rates, which were considerably lower than simulations not accounting for moisture effects. The results suggest that in... (More)
