Abstract

Numerical model predictions and experimental measurements of oscillatory sheet flow sediment transport processes are compared. The experimental data comes from full-scale experiments carried out in a large oscillatory flow tunnel. Two numerical models are considered: a 2-phase, 1DV model in which complete fluid-particle interactions are included and a 2-layer 1DV model in which the description of processes within the sheet flow layer is empirically based. Comparisons are made of measured and predicted time-varying erosion depths, velocity, concentration and flux profiles as well as net sand transport rates. The models are seen to predict reasonably well the net transport rates, especially for the medium and coarse sands, as well as much of the detailed velocity and concentration behaviour.
