Vlugtenburg

.

Vlugtenburg area is in the Delfland coast, the 15km long coastal stretch between Hoek van Holland and Scheveningen. This is one of the Zwakke Schakels (weak links) along the Dutch coastline. That means that this part of the coast is recognized as not being sustainable for the coming 50 years and in urgent need of reinforcement to guarantee the safety of the hinterland against the impact of the sea.

The sandy coast is characterized by the presence of a relatively high elevated subtidal bar.

The range between high and low waters, referred to as the tidal range, is of about 1.5m during neap tide and about 2m during spring tide.

Concerning the wind, the dominant direction is from south-west during both summer and winter season.

Waves with a significant wave height of 2.5m up hardly occur during the summer season. Besides, the summer season clearly demonstrates the prevailing, wave direction is north-west, closely followed by south-west. Concerning the winter season, the occurrence of waves with a significant wave height of 2.5m up is about 10% for each of the offshore directions. This means that on one out of ten days a wave height of at least 2.5m is observed, on average.

Data analysis points out that under moderate to rough, dominant southwesterly wave conditions the sediment has been redistributed mainly in longshore, northward direction. Offshore losses of sediment beyond the -5m depth contour line are neglected.
