Analysis of the incident sea - waves in the Rodbreak experiment

Abstract

The RODBreak experiment aimed at characterizing wave run-up, overtopping and damage in rubble-mound breakwaters with oblique wave incidence. a stretch of a rubble-mound breakwater was built in the wave basin of the Leibniz Universität Hannover. Under extreme wave conditions, with different incident wave angles (from 40° to 90°), a total of 49 tests were performed. Each test had different testing parameters, such as significant wave height (Hs), peak period (Tp) and wave direction. Also, for each test, different types of measurements were considered. This paper presents the results of processing some of the wave data measured in this experiment. After this chapter of introduction, there is a brief description of the scale model tests, focusing on the measurements made. It describes the techniques employed to analyze the measured wave data as well as the results of such processing. Some conclusions on the characteristics of the sea-waves generated in this experiment are also drawn.
