Sediments and water fluxes in a muddy coastline : interplay between waves and tidal channel hydrodynamics

Auteur(s) et Affiliation(s)



Description :
To investigate the processes that regulate sediment fluxes in muddy coastlines, the AA. measured tidal velocity and sediment concentration in Little Constance Bayou, a tidal channel in the Rockefeller State Wildlife Refuge, Louisiana, USA. The tidal measurements were integrated with measurements of wave activity in the bay at the mouth of the channel, thus allowing the quantification of feedbacks between waves and sediment fluxes. Results indicate that the sediment concentration in the channel is directly related to the wave height in the adjacent bay during flood and high slack water, whereas the concentration during ebb depends on local channel velocity.
