APPLICATION OF OVERTOPPING MODELS TO VERTICAL WALLS AGAINST STORM SURGES

[摘要] The use of different wave overtopping models has been analysed. These overtopping models were applied to vertical walls with different geometries built for the protection against storm surges in the harbour of Hamburg (Germany). A comparison of existing overtopping test data and results from specific hydraulic model tests for existing geometries in Hamburg was also performed. A simple design diagram to predict both the overtopping rate q and the required freeboard Rc is presented. Furthermore, a simple engineering approach is proposed for the reduction of the horizontal wave load of the harbour walls due to wave overtopping. Finally, conclusions are drawn to come up with a "general overtopping formula" and further research work is outlined.
