Vortex Trapping Of Suspended Sand Grains Over Ripples
--
https://doi.org/10.1029/2023JF007620 <-- shared paper
--
“KEY POINTS
• Observations of vortex-trapped grains suggest delayed settling of advected grains, as well as delayed advection of grains mobilized from the bed
• Quantitative comparisons of vortex-trapped sand grains compared well with theoretical formulations by Nielsen (1992, https://doi.org/10.1142/1269) for a forced vortex
• Improved understanding of vortex trapping effects on sediment dynamics may decrease uncertainty in large-scale coastal model predictions..."
