The present paper provides the results of an experimental and numerical investigation on a submerged rubble-mound breakwater with the aim to study its performance in terms of wave transmission in condition of large tidal range. The experimental investigation has been conducted at the EUMER laboratory of the University of Salento. In the 2D wave flume, a small-scale physical model of a submerged breakwater has been constructed and exposed to different wave conditions and water levels. The experimental observations have been used to calibrate the numerical model CSHORE and to investigate the fraction of the different energy dissipative contributions due to wave breaking, to bottom friction and to porous mound. Additional tests have been numerically conducted to cover a wider range of wave conditions and water levels, allowing to better evaluate the behavior of the submerged rubble-mound breakwater in condition of large tidal range.

Abstract
The present paper provides the results of an experimental and numerical investigation on a submerged rubble-mound breakwater with the aim to study its performance in terms of wave transmission in condition of large tidal range. The experimental investigation has been conducted at the EUMER laboratory of the University of Salento. In the 2D wave flume, a small-scale physical model of a submerged breakwater has been constructed and exposed to different wave conditions and water levels. The experimental observations have been used to calibrate the numerical model CSHORE and to investigate the fraction of the different energy dissipative contributions due to wave breaking, to bottom friction and to porous mound. Additional tests have been numerically conducted to cover a wider range of wave conditions and water levels, allowing to better evaluate the behavior of the submerged rubble-mound breakwater in condition of large tidal range.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
