Resumen
Numerical calculation of flow structure and the suspended sediment concentration over seaweed bed under surface wave is conducted using the k- E turbulence model. Velocity distribution and suspended sediment concentration over seaweed bed, which is made of a plastic sheet, are measured by use of the electromagnetic current meter and a turbidity meter, respectively. The characteristic phenomenon such as the vortex formation over seaweed bed is simulated and the calculated vertical profile of suspended sediment concentration is similar to that of experiment. The value of drag force coefficient of seaweed is a few times larger than that of rigid seaweed.
