Van der Neut, E.M. (author)When designing a rubble mound breakwater, one would like to predict the stability of the armour layer of the breakwater. For this purpose several armour layer stability formula are developed. The most reliable is considered to be the stability formula of Van der Meer (1988). With this method, the armour layer stability is predicted based on...master thesis 2015

Mellink, B.A. (author)The design formula for rubble mound breakwaters by Van der Meer has an unclear Notional Permeability term. This term causes a lot of confusion for designers. In the past many people have tried to derive a better formulation for that term by experimental and analytical research. The goal of this study was to obtain a better formulation along a...master thesis 2012

Zeelenberg, W. (author), Koote, M. (author)In this report will be explained how breakwaters can be made with the use of Elastocoast, a sort of glue. This makes it possible to fix the individual rocks, and allows repetitive tests possible with exactly the same layer properties. We made six samples of breakwater rock layers, made with Elastocoast and stones, which can be placed and tested...bachelor thesis 2012

Van Broekhoven, P.J.M. (author)In JUMELET [2010] a method with a physical basis (so called “Volume Exchange model”) to determine the ‘notional’ permeability coefficient P was developed. The ‘notional’ permeability coefficient was previously introduced in the stability formula of the armour layer; see VAN DER MEER [1988]. In this latter study this coefficient was empirically...master thesis 2011

Jumelet, H.D. (author)This study describes a theoretical approach of a physical description of the notional permeability factor in the stability formulae of Van der Meer [1988]. Caused by the empirical character of these stability formulae a physical description is not available for the notional permeability factor. In practice this leads to ambiguities in...master thesis 2010
