Average wave overtopping discharges for complex geometry: A case study for the prediction of average wave overtopping discharges with stepped revetment in the cross-section

Witteveen+Bos as part of construction consortium Nautilus, has prepared the design of a sea defence system in Middelkerke. The very shallow water conditions (h/Hm0 = 0.3) and complex geometry of the structure, i.e. a high berm and stepped revetment, caused uncertainties in the usage of the empirical equations from the EurOtop Manual (2018) for...

Validation of Swash for wave overtopping

Comparison of measured overtopping data with computations with Swash. The SWASH output discharges are smaller than the 5% lower limit of Eurotop and Neural Network predictions. Nevertheless, they were close values and they have the same order of magnitude, which is very important when comparing overtopping values. No refection analysis was done....
