Beach nourishment is not a new method, but it hasn’t been applied in this region since the 80s, so the beaches almost lost their capacity. Nowadays, their width is much decreased due to the erosion. Submerged breakwaters and the existing structures functioned well in the beginning of their operation when they were built, but nowadays their effect is almost negative because they stop the sediment transport that is predominantly from north to south, which is the natural way of beach nourishment. So, most of the beach is deprived of sediments.
