“…Devising a headland bay beach system in static equilibrium in such a way that the reorientation of the shoreline cancels the longshore sediment transport is called "headland control", and can be considered as a valuable option for coastal stabilization, which is frequently addressed via traditional detached low-crested breakwaters [5,6] or artificial reefs [7,8].…”

For crenulate-shaped bays, the coastal outline assumes a specific shape related to the predominant waves in the area: it generally consists of a tangential zone downcoast and a curved portion upcoast. Many coastal engineers have attempted to derive an expression of the headland bay shapes that emerge when a full equilibrium is reached (stable or dynamic). However, even though models for static equilibrium bays exist, they are merely of an empirical kind, lacking further insight on relationships between incident wave characteristics and beach shape. In addition, it is commonly believed that shoreline profiles tend to follow wave fronts, but this has been never fully verified. In this paper, we investigate a possible correlation between static equilibrium profiles and wave front shapes. Numerical experiments have been performed using the MIKE 21 Boussinesq Wave module, and the generated wave fronts have been compared to the hyperbolic-tangent equilibrium profile. A thoughtful analysis of results revealed that a single-headland equilibrium profile is merely the wave front translated perpendicularly to the wave direction at the headland tip, without any influence of wave period or in wave direction. A new function called the “wave-front-bay-shape equation” has been obtained, and the application and validation of this formula to the case-study bay of the Bagnoli coast (south-west of Italy) is described in the paper.

“…The relationship between the hydrodynamic characteristics and the ecological environment construction of artificial reefs is still unclear. With the severe erosion of the global coastline and the shortage of renewable energy, some researchers began to combine artificial reefs with the underwater breakwaters, the wave-dissipating structures, and the renewable energy devices (Srisuwan and Rattanamanee, 2015;De Almeida, 2017;Jiao et al, 2017;Kim et al, 2020;Ghiasian et al, 2021;Marin-Diaz et al, 2021). These multi-functional artificial reefs can not only fulfill the functions of ocean structures, but also enrich the diversity of marine organism.…”

Artificial reefs are beneficial to restore fishery resources and increase fishery production. Meanwhile, they play a significant role in improving ocean ecology and accelerating the evolution of fishery industries. Since they are generally affected by currents, waves, and other hydrological factors, the flow field around artificial reefs and their stabilities have become a research hotspot in recent years. Research on artificial reefs is a systematic process consisting of four aspects: Firstly, the significance, the definition, the mechanism, and the present research progress were introduced for artificial reefs in detail. Secondly, the development trend of the sit-bottom artificial reef and that of the floating artificial reef were summarized, respectively. Thirdly, it was found that the combination of traditional artificial reefs and emerging ocean engineering has a great development potential in practical engineering. Finally, the existing problems related to the hydrodynamic characteristics of the artificial reefs in China were summarized, and the prospects of artificial reefs were proposed. The purpose of this study is to provide a scientific reference for the ecological and sustainable development of the large-scale construction of artificial reefs in the ocean.

“…First, positive attitudes were expressed towards natural reefs and stream deltas [22]. As an alternative method for dealing with increasing erosion pressures with limited resources, artificial reefs range from rock mounds parallel to the shore to prefabricated units with various types of structures, such as a concrete box, tunnel, dome, leg, or more complex shapes [25,26] with features of submergence and porosity. The deployment objectives in recent research have shifted from improving fisheries as a resource to rehabilitation of the marine ecosystem, improving surfing or diving conditions, recreational fishing, and coastline protection [27].…”

For observation on the influence mechanism of environmentally and aesthetically friendly artificial submerged sand bars and reefs in a process-based way, a set of experiments was conducted in a 50 m-long flume to reproduce the cross-shore beach morphodynamic process under four irregular wave conditions. The beach behavior is characterized by the scarp (indicating erosion) and the breaker bar (indicating deposition), respectively, and the scarp location can be formulated as a linear equation regarding the natural exponential of the duration time. Overall, main conclusions are: (1) the cross-shore structure of significant wave height and set-up is mainly determined by the artificial reef (AR); (2) the cross-shore distribution of wave skewness, asymmetry, and undertow (indicating shoaling and breaking) is more affected by the artificial submerged sand bar (ASB); (3) the ASB deforms and loses its sand as it attenuates incident waves, which leads to a complex sediment transport pattern; (4) the scarp retreat is related to the beach state, which can be changed by the AR and the ASB; (5) the AR, the ASB, and their combination decrease wave attack on the beach. In conclusion, this study proves positive effects of the AR and the ASB in beach protection through their process-based influences on beach behaviors and beach states for erosive waves.
