Fig. 4

Comparison between the experimental and simulated evolution of sediment transport: (above) simulated morphology of sediment in volume concentration at 10 s and 15 s, respectively (DPM 10); the dotted lines indicate the sediment profile at the similar view to the experimental observation; and (below) observed morphology of sediment after particle injection for 10 s and 15 s, respectively; the dotted lines indicate the sediment profile from the simulated results at the same time for comparison
