New results on scale effects for wave overtopping at coastal structures, the CLASH programme

It is proven that wave run up on rough slopes is underestimated in small scale model tests due to scale / model effects. Given this fact, the same effects are suspected to be present for wave overtopping. A thorough comparison between prototype measurements of wave overtopping at three different coastal structures and scale model tests of these...

Report on additional tests – Part C: Influence of low wave steepness

Within the framework of the CLASH-white spot tests, wave overtopping tests on a smooth sloping structure have been performed at UGent. 3 different geometries have been tested during these tests 1) simple smooth dike 2) simple smooth dike with a small vertical part (same crest level as geometry 1) 3) simple smooth dike with a small vertical part...

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...

Sytnthesis and design guidelines for overtopping

The CLASH project (Crest Level Assessment of Coastal Structures by Full Scale Monitoring, Neural Network Prediction and Hazard Analysis on Permissible Wave Overtopping, www.clash-eu.org) funded by European Union (EU) through contract no. EVK3-CT-2001- 00058, investigated wave overtopping for different structures in prototype and in laboratory ...

Final report on laboratory measurements on the Ostia case

Within WP4.2 laboratory investigations for the Ostia rubble mound breakwater are performed in the wave flume of Ghent University (later UGent) and in the wave basin of Flanders Hydraulics (hereafter FCFH). In order to check any influence that is typical for laboratory measurements and to identify possible causes for differences in results, tests...

Report on full scale measurements in Zeebrugge, 2nd full winter season

The present report describes the full scale measurements at the Zeebrugge breakwater within the framework of Workpackage 3: Full Scale Measurements of the CLASH-project. First a general description of the field site is given. Afterwards, two types of full scale measurements are described: on the one hand the wave overtopping measurements and on...
