(Figure 6a) Computed wave parameters and critical velocities for two dominant grain sizes

Seabed-orbital velocity (calculated using model runs on wave data and equation (5), from which the 10% (fair), 50% (median) and 90% (storm) probabilities were calculated). The critical velocities for the two dominant grain sizes (150 mm and 400 mm) that were calculated using equations (6) and (7).
