Abstract
The variety of design formulas for the determination of wave action (run-up, overtopping) at coastal structures indicates uncertainties in the interpretation of results from hydraulic and numerical model tests. Two sources of data scatter are discussed in the following: varying statistics of wave heights in the irregular wave trains used in the physical models the use of the reference wave parameters at the toe of sloped sea dikes, recommended in the more recent literature without considering energy flux (shoaling) and possibly refraction effects. To quantify the influences of wave irregularity, overtopping rates from regular wave tests were used in combination with the probability calculation method to calculate irregular wave results at vertical walls. The range of the influence of the reference wave height parameter in case of sloped structures is demonstrated by varying the reference water depth and applying the currently recommended design formula from EurOtop; furthermore by measurements in regular waves. The influence on wave run-up in oblique waves is demonstrated on the basis of measurements in irregular waves.
