Wave overtopping and scale effects: Experimental case study New Afsluitdijk

After more than 85 years, the iconic Afsluitdijk is in need of a reinforcement. During the latest safety assessment of Rijkswaterstaat the dike did not meet the standards at two components; the amount of wave overtopping (>10 l/m/s) and armour stability. This research goes into detail about the overtopping on the Afsluitdijk. In the new...

Wave impacts on storm walls, a study on scale effects

Low-lying countries such as Belgium and the Netherlands are naturally susceptible to overtopping wave attacks. Coastal regions are therefore facing the threat of such events causing damage to dike-positioned structures and buildings. Research in this filed is often conducted using scaled-down 2D hydraulic physical models, which introduces so...

Quantification of measurement errors, model and scale effects related to overtopping

CLASH is concentrating on investigations of wave overtopping for different structures in prototype and in laboratory. The model investigations have focussed on wave overtopping and the comparison of overtopping results from small-scale model tests and prototype measurements. Possible differences in the results from small-scale tests and...

Laboratory measurements on the Zeebrugge breakwater

Within WP4 laboratory investigations for the Zeebrugge rubble mound breakwater have started in the wave flume of Leichtweiß-Institute for Hydraulic Engineering of the Technical University of Braunschweig (hereafter LWI) and in the wave flume of the Universidad Politécnica de Valencia (hereafter UPVLC). In order to check any influence that is...

Final report on laboratory measurements Samphire Hoe

Following this introductory section, Chapter 2 discusses the Samphire Hoe field measurements and results, Chapter 3 the design and operation of the laboratory measurements and the results are described in Chapter 4. Finally in Chapter 5 the data are compared and the principal conclusions are given.
