ABSTRACT

The hydraulic performance and wave loads of single screens and chamber systems were investigated within an extensive test programme in the Large Wave Flume (GWK), Hannover, of the “Forschungszentrum Küste (FZK)”, a joint coastal engineering research centre of both universities of Hannover and Braunschweig. A comparison of One- and Multi-Chamber-Systems in terms of the reflection properties and the wave loads demonstrates the advantages of systems with more than one wave chamber. The analysed phase lag between front wall and rear wall of One-Chamber Systems is also investigated and discussed in this paper.

RÉSUMÉ

L'efficacité hydraulique d'écrans simples et des systèmes à chambre(s) a été étudiée du point de vue fonctionnement et sollicitations hydrauliques lors d'un vaste programme expérimental dans le Grand Canal à Houle (GWK) de Hanovre. Une comparaison des systèmes monochambre et multichambre en termes de pouvoir réfléchissant et des efforts de la houle illustre clairement les avantages des systèmes multichambres. Les différences de phase entre la paroi amont et la paroi arrière sont également examinées.
