Dynamic Cobble beaches as sea defence

Van Gent, M. R. (2010). Dynamic cobble beaches as sea defence. In Proceedings International Coastlab Conference 2010.

The study presented here focussed on fundamental aspects of revetments with dynamic rock slopes and gravel beaches. Obviously, the response of gravel beaches and cobble beaches depend on parameters such as the wave height and the stone size. Here, other parameters such as the permeability of the subsoil and the influence of sand in the pores of gravel have been studied. This study is based on laboratory investigations in three types of facilities: A wave flume for small-scale tests, a wave flume for large-scale tests at a close-toprototype scale, and a wave basin for 3D tests. The results also provide insight into the magnitude of scale effects.
