OBREC was demonstrated to capture the waveenergy similarly to TRMBs. The introduction of the nose was shownto be indispensable to limit the structure overtopping, but at thesame time the wave loading on the structure increased by thepresence of the nose. According to the experiments, OBREC wascharacterized by average reflection coefficients as for TRMBs. It wasconvenient, by the way, to develop the research on OBREC performance to understand how to increase the wave overtoppingdischarge in the front reservoir without augmenting the reflectioncoefficient.
