Storm surge caused sheet flows in coastal regions lead to massive amount of sediment transport. We conducted full-scale lab experiments to study sheet-flow sediment transport for a sloped bottom. Net transport rates were measured and analysed.
A semi-analytical model was proposed for coastal sheet flow sediment transport
A two layer numerical model was proposed and developed in MATLAB for coastal sediment transport.k−ωmodel was used.
Wall-modelled LES was developed and applied to study vortex ripples based on OpenFoam.
