Fundamental aspects related to sediment transport in sandy coasts

Marine sediment transport processes occur mainly in coastal areas, where the presence of waves and slowly varying currents is the main hydrodynamic feature. Several processes taking place at different time and space scales are involved. On the inner shelf, waves generate turbulence next to the bed largely responsible for sediment resuspension. Over the bottom boundary layer, mean currents control horizontal motion of suspended sediment while the falling of grains is compensated by the upwards diffusion resulting from the turbulent motion close to the bed . Here, the total stress depends on the... Mehr ...
