On an exposed sandy beach coastal impacts and sedimentation are important aspects in the optimization of a harbor layout. Hanstholm harbor on the West Coast of Denmark is an example of a very successful harbor located near a headland on an exposed coastline. The harbor is a fishery and ferry port originally designed by Professor Helge Lundgren and was built in the 1960s at a critical location with about 0.4 million m3/year net northward transport and a gross transport of around 1.5 million m3/year. The symmetrical and streamlined layout creates a smooth convergence of the flow past the harbor entrance and has in combination with vertical breakwaters resulted in acceptable sedimentation rates both updrift of the entrance and within the outer harbor. The sedimentation is localized in the outer harbor immediately inside the entrance, and a natural depth in the entrance area is about 9 m. The average yearly sedimentation in the harbor is 80,000 m3. The flow around Hanstholm harbor is mainly driven by meteorological forcing, variations in wind and pressure, and, to a less extent, by wave breaking. Tide is very limited in this area. An extension is planned on the western side of the existing harbor. The implications of the extension on the sedimentation in the outer harbor are the topic of the present paper.
