Abstract Careful design of the high-tech semi-circular breakwaters (SBW), which are used for protection against sea waves, is essential to avoid failure these large-scale projects. An improved tool adopting numerical simulations, complemented with experimental measurements introduced. Unstructured boundary-fitted grids model curved SBW boundary accurately and resolve flow adjacent it. Experimen...

Nowadays, the existence of a huge number aging harbor defense structures and climate change-induced forcing variability highlight need for methodology able to deal with uncertainties which arise during design new above all upgraded structures. In present work, probabilistic based on Monte Carlo simulation technique assessment failure probability due independent modes factor change method inclus...

The floating breakwater is a protective structure that can absorb waves and be used effectively in coastal areas with moderate wave environmental conditions. stability of the affected by tension mooring line weight anchor. This research was conducted experimentally model scale 1:10 on systems concrete anchor blocks three types configurations. experiment carried out irregular following variation...

This paper utilizes ANSYS-AQWA hydrodynamic simulation analysis software (2022 R2) to investigate the wave dissipation performance of an Oscillating Water Column (OWC) perforated floating breakwater under irregular conditions. The study examines effect spacing, width OWC opening, water depth, incident angle, and significant height on breakwater. results indicate that OWC-perforated surpasses si...

It is widely recognised that coastal-defence structures generally affect the structure of the assemblages they support, yet their impact on adjacent systems has been largely ignored. Breakwaters modify the nearby physical environment (e.g. wave action) suggesting a local impact on biological parameters. In the present study, an ACI (After-Control-Impact) design was used to test the general hypo...

Most coastal structures have been built in surf zones to protect coastal areas. In general, the transformation of waves in the surf zone is quite complicated and numerous hazards to coastal communities may be associated with such phenomena. Therefore, the behavior of waves in the surf zone should be carefully analyzed and predicted. Furthermore, an accurate analysis of deformed waves around coa...
