A small-scale field experiment on a submerged breakwater for absorbing wave energy

The paper concerns results obtained in a small-scale field experiment on Boccotti’ submerged caisson breakwater, which absorbs wave energy and is able to defend a coast with a very small environmental impact. An experiment on the 1:10 scale model of a caisson of this breakwater was carried out on a seabed 2.6 m deep. All the records of the experiment confirmed that it is possible to obtain a strong natural resonance between the random process of wave pressure at the outer opening of the caisson and the random process of oscillations inside the caisson. Furthermore the paper shows a test on both the computational algorithm, by means of the output of the field experiment, and a procedure for tuning the plant.
