Evolution of a Beach With and Without a Submerged Breakwater: Experimental Investigation

In the present report experimental results about the efficiency of a submerged structure are presented. The experiment, carried out with random waves, covered about 2500 hours until equilibrium profile was reached. The most significant results are the good behaviour of the tested breakwater as a sand holding structure and its slowing effect produced on the shoreline backing, whereas the final position of the shoreline was nearly the same with and without breakwater.
