Comparison of existing formulae for estimating the overtopping rate in harbour breakwaters

The research that is summarized in this article, resultant of diverse studies realized in the CEDEX, has for object a comparative analysis of methods of overtopping rates developed by different authors. For that, the summary was realized first and the analysis of the existing formulations to estimate the rate of overtopping on rubble mound and vertical breakwaters. Later, there was carried out the contrast of the above mentioned formulations by the results obtained in a serie of hydraulic model tests of the Hydraulic Research Laboratory (the Center of Studies of Ports and Coasts of the CEDEX, Madrid, Spain).

Comparison of Existing Formulae for Estimating the Overtopping Rate in Harbour Breakwaters

The purpose of the research work resulting from various studies undertaken in the CEDEX, as summarized in this article, is to make a comparative analysis of methods for calculating overtopping rates developed by different authors. To this effect, in the first place, existing formulae for estimating the overtopping rate on rubble mound and vertical breakwaters were summarised and analysed. Later, the above mentioned formulae were compared using the results obtained in a series of hydraulic model tests at the CEDEX (the Center of Studies of Ports and Coasts of the CEDEX, Madrid, Spain). A calculation method based on the neural network theory, developed in the European CLASH Project, was applied to a series of sloping breakwater tests in order to complete this research. The results obtained in the Ferrol, Ciervana and Alicante breakwaters tests are presented here.
