Shoreface Connected Ridges Along the Dutch Coast

Document Type: Proceeding Paper

Part of: Coastal Sediments

Abstract:

Quasi-synoptic current measurements were obtained across the Dutch shoreface connected ridges using an acoustic Doppler current profiler. The measurements are used to evaluate the role tidal currents play in the formation and maintenance of these ridges. The data show marked differences between the flow patterns during ebb and flood. During ebb, the flow veers towards the crest as predicted by Huthnance (1982), whereas during flood no flow response was observed. Residual currents (averaged over one tidal cycle) show a net landward directed cross-bank component.
