The transport of fine sediment transport basins: Humber case study

This report describes the processes that govern the net transport of fine sediment in the mouth of estuaries and tidal basins in general, and of the Humber mouth in particular. These processes have been identified on the basis of literature surveys and further analysis of data and numerical modelling results. From these analyses it is concluded that: The net sediment import into estuaries and tidal lagoons is largely governed by channelshoal interactions. Moreover it is concluded that the water-bed exchange processes on these intertidal areas is much larger than commonly predicted with the current class of engineering models for cohesive sediment predictions. Further distribution of the fine sediments within estuaries and tidal lagoons is governed by temporal variations in driving forces and biological activity.
