Entrance
to Bembridge Harbour demonstrating the complex configuration of the inlet
and the abundance of sediment seaward of the harbour entrance (21.09.98).
Bembridge Point (1) and its attached intertidal sandbank (2) have grown
northward progressively infilling and deflecting the tidal channel. The
St Helens Duver (3) a vegetated dune system has grown southward by shore
drift. A notable flood tidal delta (4) has developed as silt and sands
are driven into the inlet. A morphological interpretation of the main
directions of transport is indicated by the arrows. Sediments entering
the main inlet channel are believed to be transported seaward by tidal
currents eventually becoming re-circulated shoreward by wave action. Sediments
may therefore bypass the inlet and move northward towards Nettlestone
Point.
