| Abstract |
A new shallow water wave basin has been built at Flanders Hydraulics Research. One of the interests is to study the effect of very shallow foreshores on wave directional spreading and overtopping processes for three-dimensional sea states. To do that, the basin has been equipped with a multi-directional piston-type wave generation system and a measurement system up to sixty-two devices. The main characteristics of the new wave basin are described in the present work, together with the first experimental campaign that has been carried out in it. The model tests consist of long- and short-crested waves interacting with sea dikes in presence of a very shallow and gentle foreshore slope. On top of the sea dikes, vertical walls are built to mimic the presence of apartment buildings. Such a dike layout configuration, very typical for low-lying countries, is defined as a multi-functional sea dike. The experimental campaign is one of the few cases of a detailed study of wave overtopping and post-overtopping processes in very shallow water conditions and for three-dimensional sea states, which will provide a unique database for numerical model validation and new insights of the effects of shallow water conditions on phenomena dominated by the so-called infragravity waves. |
