Environmental impact of submerged and emerged breakwaters. [PDF]
Heliyon, 2022 السواحل مهددة باستمرار بالتآكل. هناك حاجة متزايدة إلى هياكل دفاع ساحلية فعالة ذات آثار بيئية أقل. تم تنفيذ حواجز الأمواج المغمورة والناشئة على مستوى العالم، بينما أحدثت تأثيرات إيجابية أو سلبية على البيئة. أحد أهم المخاوف في تطبيق حواجز الأمواج هو كيفية تقليل عواقبها غير المرغوب فيها على البيئة.

International Journal of Naval Architecture and Ocean Engineering, 2020 A numerical model is established to investigate the run-up of a solitary wave after propagating over a triangular saw-tooth-shaped submerged breakwater. A rectangular-shaped submerged breakwater is simulated for comparison. Several factors, including the

SEABED SCOUR AROUND SUBMERGED BREAKWATER [PDF]
The Egyptian International Journal of Engineering Sciences and Technology, 2005 This research presents the results of an experimental study on seabed scour around a submerged breakwater exposed to regular waves. The transmission coefficient as well as the maximum equilibrium scour depth and maximum equilibrium deposition height recorded for different wave frequencies and different relative breakwater heights.

Wave Transmission by Rectangular Submerged Breakwaters [PDF]
Computation, 2020 In this paper, we investigate the wave damping mechanism caused by the presence of submerged bars using the Shallow Water Equations (SWEs). We first solve these equations for the single bar case using separation of variables to obtain the analytical solution for the wave elevation over a rectangular bar wave reflector with specific heights and lengths.

Journal of Marine Science and Engineering, 2023 Submerged breakwater, as an important marine engineering structure, can effectively absorb wave energy and is widely used in marine engineering protection. As a new type of breakwater, porous medium breakwater has a certain influence on wave propagation.
