| Abstract |
| Overtopping calculaiton method using SWASH was defined in the methodology book (cfr 14_014) for the safety assessment 2015. However this method does not give so much differences in overtopping discharges between 2 different bathymetry conditions, with and without a dry sandy berm in front of dike. This is because no bottom friction was used in SWASH (n=0.000). In this project a new bottom friction setting will be explored in order to take into account the influence of sandy berm for the overtopping calcualtion. On top, influence of the infiltration (ground water flow) will be also investigated |
