Full-Scale Measurement of Wave Overtopping at Ostia-Rome Yacht Harbour Breakwater

This paper describes new wave overtopping field measurements at Ostia yacht harbor breakwater (Rome, Italy). The structure, the measurement strategy and the equipment are described in some details. Preliminary results of a recently measured overtopping storm, which are occurred in October of 2003, are presented in the paper. The activities are carried out within the framework of the European Union research project CLASH, aimed at studying model scale effects in overtopping studies and at providing scientific and professional communities with reliable crest level design criteria for coastal structures.
