Optimised Harbour Layout

Facing the need to accommodate larger fishing vessels, Hvide Sande Harbour, on the very exposed West Coast of Denmark with a net littoral drift in the order of 1,000,000 m³/year, wishes to increase the navigation depth in front of the harbour entrance while at the same time reducing the sedimentation in the access channel.

In collaboration with the Danish Coastal Authority and Hvide Sande Harbour, a new scheme has been developed by DHI consisting of a combination of new streamlined breakwaters to increase the bypass of sediment past the harbour mouth and a dredged retreat of the coastal profile to help maintain the required additional water depth needed. The morphological study carried out showed that the proposed scheme results in an increased equilibrium depth of the bypass bar in front of the harbour without increasing the downdrift erosion, and an improved natural bypass of the littoral drift.
