“…In the region of Niigata, the offshore abrasion of the bottom is up to 1 m (Funakoshi et al, 1994;Homma and Horikawa, 1961;Kuroki et al, 2002;Ranasinghe and Turner, 2006;Shiraishi et al, 1960). In the case of Pellestrina (the Adriatic Sea), the bottom was strongly abraded as a result of intensive flows and eddies Sumer et al, 2005;Zyserman et al, 2005).…”

“…In many cases, however, they have not produced the desired effects. Waves energy dissipation was too small (Lamberti and Mancinelli, 1996;Ranasinghe and Turner, 2006), while the bottom in the neighborhood and in the shade of the construction was extensively washed out (Burcharth et al, 2007;Funakoshi et al, 1994;Homma and Horikawa, 1961;Kuroki et al, 2002;Lamberti et al, 2005;Shiraishi et al, 1960;Sumer et al, 2005;Zyserman et al, 2005). Positive effects have been observed in addition to adverse ones.…”

Submerged breakwaters (SBWs) were used for the first time on the Polish coast in 2006, in the western coast of Gdańsk Bay, in the area of Orłowo Cliff. They were built to prevent the abrasion and inundation of areas situated in the hinterland, especially in the conditions of storm surges. The main objective of the study was to determine their effect on the morphology and grain size composition in the seashore and nearshore zone.Based on the conducted research and analysis, it has been found that the construction has a minor impact on the modification of the shore and nearshore zone morpholithodynamics, which is evidenced by a sinuate shape of the shoreline and a relatively stable cape in the central part of the area, present both before and after SBWs were built. Furthermore, the progressive abrasion, the lack of significant changes in the morphology and particle size distribution of the beach and the nearshore zone, as well as the fact that those changes are limited only to the immediate surroundings of the submerged breakwaters prove their neutral impact.
