Environmental impact of submerged and emerged breakwaters. [PDF]

open access: yesHeliyon, 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.

Experimental and Numerical Study of the Nonlinear Evolution of Regular Waves over a Permeable Submerged Breakwater

open access: yesJournal of Marine Science and Engineering, 2023
The permeable submerged breakwater has gained popularity in recent days due to its merits of reducing incident wave energy without negatively impacting the aesthetics of the ocean view and allowing for water exchange.

Numerical Study on the Effects of the Multiple Porous Medium Breakwaters on the Propagation of the Solitary Wave

open access: yesJournal 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.

Numerical study of the run-up of a solitary wave after propagation over a saw-tooth-shaped submerged breakwater

open access: yesInternational 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

Numerical Study on Hydrodynamics of Submerged Permeable Breakwater under Impacts of Focused Wave Groups Using a Nonhydrostatic Wave Model

open access: yesJournal of Marine Science and Engineering, 2022
Extreme waves, called rogue waves or freak waves, usually occur unexpectedly and with very large wave heights. In recent years, extreme waves were reported not only in deep ocean waters but also in shallow waters, which threaten the safety and intactness

Non-Hydrostatic Numerical Model of Bragg Resonance on Periodically Submerged Breakwater

open access: yesJournal of Marine Science and Engineering, 2023
The Bragg resonance (BR) of a reflection coefficient resulting from the propagation of monochronic waves over periodically submerged breakwater was studied using the non-hydrostatic numerical model SWASH (Simulating WAves till SHore).
