Brady Couvillion
2023, Report, 2023 Louisiana’s comprehensive master plan for a sustainable coast
Coastal Louisiana is a complex landscape. The composition of the landscape, as well as the processes which influence said landscape, vary in both space and time. The models used in the 2023 Coastal Master Plan must attempt to reflect that spatial and temporal variability. It is therefore of the utmost...
Vortex trapping of sand grains over ripples under oscillatory flow
Donya P. Frank-Gilchrist, Allison Penko, Margaret L. Palmsten, Joseph Calantoni
2023, Conference Paper, Proceedings of MARID VII
Sand ripples significantly impact morphodynamics in the nearshore by generating coherent vortices, which can transport suspended sediment to greater heights in the water column than above flat beds. Coherent vortices can trap sediment grains if the settling velocity of the grain is smaller than the maximum vertical fluid velocity in...
