Van den Bos, J.P. (author), Verhagen, H.J. (author), Kuiper, C. (author)This paper presents the results of a systematic validation of numerical simulation of reflection and transmission of rubble-mound breakwater structures. The aim of the study is to provide a body of validation measurements for increasingly complex situations, starting simple and building up the comlexity in terms of breawater geometry, wave...conference paper 2015

Van den Bos, J. (author), Verhagen, H.J. (author), Zijlema, M. (author), Mellink, B. (author)A more detailed understanding of porous flow inside a rubble-mound structure may have potential benefits in breakwater design. Numerical models are expected to be a useful additional research tool in this field, provided that their calculation results can be validated against measurements. This paper presents the results of a systematic effort...conference paper 2014

Kik, R. (author), Van den Bos, J.P. (author), Maertens, J. (author), Verhagen, H.J. (author), Van der Meer, J.W. (author)Different layer design of a rock slope and under layers has a large effect on the strengths on the rock slope itself. In the stability formula developed of VAN DER MEER [1988] this effect is represented by the term Notional Permeability with symbol P. A more open, or permeable, structure underneath the armour layer has the ability to dissipate...conference paper 2012

Van den Bos, J.P. (author), Verhagen, H.J. (author), Olthof, J. (author)The Paintal (1967) formula can be used to estimate transport rates of coarse-grained bed material (such as stones from a bed protection) under low hydraulic loads just above the threshold of motion; the application however is limited to steady currents. This paper presents research aimed at extending the range of application to a combination of...conference paper 2010
