A theory on reflection of nonlinear short-crested wave groups

For marine and coastal structures, that are totally reflective and subject to the action of sea waves, it is necessary to evaluate the correct wave pressures acting on the structure and the relative wave loads. In fact, they both represent a key factor into the design process and a fundamental aspect, which has to be analysed, for the stability analysis of these coastal structures. By applying the nonlinear solution, derived in this study, for the interaction between wave groups and a reflective breakwater, the effect of non-linearity on the wave pressures will be analysed, when an exceptionally high crest elevation occurs on the structure.
