| Abstract |
There is a chance that storm surges occurring in coastal areas cause overtopping over wide crested dikes. The overtopping water results in a hydrodynamic load on the structures built on top of the dike crest. This is for example the case at the Belgian coast where houses and hotels are constructed on top of sea dike crest. In the present study, physical model tests were carried out on a schematized model scale 1:30. The main aim is to develop a relationship to describe the force on a vertical plane exerted by the overtopping water as a function of wave parameters and geometrical characteristics. Due to time limitations the number of flume tests had to be restricted to only a limited number of parameters which can be varied. Despite these restrictions, the experiments revealed the most important mechanisms of the wave impact processes for two dike configurations. The first configuration includes: the dike side case with dike crest width of 0.0 m and the inland case with dike crest of width 0.50 m in model scale. |
