A sea-dike system is of importance for the protection of the hinterland. However, the effect of very gentle and shallow sloping foreshores (in the order up to 1 in 1000) on wave overtopping processes has not yet been quantified enough and, thus, so far is not well understood. This dissertation seeks an answer to the question of whether the existing formulae are suitable for these slopes, and which approach is the most appropriate to quantify the wave overtopping discharge and volume for these typical (e.g. gentle and shallow) slopes. Along the way, comparative research between the results of numerical analysis and those of existing studies is conducted. Subsequently, new empirical equations are formulated, using a series of test cases in the numerical modeling for this type of slopes, using a Least Squares method.
First, recent state-of-the-art research for wave overtopping behavior and the relevant parameters is investigated.
