Suspended sediment concentration profile in flow through a Typha latifolia canopy

This study used laboratory experiments and random displacement model (RDM) to investigate the distributions of suspended sediment concentration (SSC) within a Typha latifolia canopy. The SSC profile in the Typha canopy differed significantly from the profile in open channel. a model for vertical diffusivity was validated with tracer data within cylinder array and then modified to reflect the specific morphology of the Typha canopy. RDM simulations using the modified diffusivity model produced good agreement with the measured suspended sediment concentration. This work could provide insight into guiding marsh restoration and land-building.
