In this work, we investigate the interaction between the combination of wind-driven
and regular waves and a chamber defined by a rigid wall and a thin vertical semi-submerged barrier.
A series of laboratory experiments were performed with different values of incident wave height,
wave period, and wind speed. The analysis focuses on the effect of the geometry of the system
characterized in terms of its relative submergence d/h and relative width B/L. Results show that for
the case of d/h = 0.58 a resonant effect takes place inside the chamber regardless of the wind speed.
Wind-driven waves have a higher influence on the variation of the wave period of the waves seaward
and leeward of the plate, as well as on the phase lag. Results show that the amplification or reduction
of the wave energy inside the chamber is closely related to the wave period as compared to the 1st
order natural period of the chamber.
