Special Issue Information

Dear Colleagues,

Coastal environments are some of the most populated on Earth, but with greater challenges projected in the future due to climate change and urbanisation, their healthy existence is increasingly perilous. Increased storm surge, flooding and erosion due to sea-level rise (SLR) and land subsidence (LS) are major natural hazards that coastal regions will face in the 21st century, with potentially high socioeconomic impacts. Furthermore, industrial spillages, effluents from sewage, refineries, urban and storm water runoff or oil leakages from broken ships can cause water quality issues, especially if the contaminants are dispersed under specific wave and current conditions, generating impacts on the livelihoods of people, public health and local water quality.

Therefore, there is a strong need to develop sustainable techniques that could protect coastal regions from meteorological and hydrological hazards and the diffusion and dispersion of pollutants. Additionally, a better understanding of coastal processes, which is significant to coastal protection, is highly encouraged. Furthermore, it is necessary to provide better predictions and improve the modelling of the influence and the secondary effects that coastal structures may have on local conditions, taking into consideration future uncertainties associated with climate change and urbanisation.

By protecting against storm damage, flooding and erosion, these living habitats can keep people safe and can help to mitigate economic loss of personal and public property, cultural landmarks and natural resources.

This Special Issue is set up to receive original research papers investigating the hydrodynamics, sediment transport, beach erosion, water quality and ecology of coastal environments to improve the scientific understanding of coastal processes as well as to identify new sustainable coastal protection structures or optimize existing ones. This Special Issue is open to experimental and numerical studies, theoretical ones and field works.

An artificial floating reef is an important part of the coastal ecological corridor. The large-scale construction of floating reefs by optimizing mooring methods can effectively improve the ecological effects of coastal projects. The artificial floating reef belongs to coastal engineering, and wave resistance is fundamental to its structural design. In this paper, the method for processing coupling forces and motion, the method for judging the floating reef out of water surface, and the method for correcting velocity and acceleration of water mass points are elaborated in detail by using the finite element method and lumped-mass mooring model. By comparing and analyzing the results of physical experiment and numerical simulation, the correctness of the numerical model is verified. Finally, the diachronic variation of pitching angle of floating reef, the tension of the mooring rope, and the total tension of the fixed points of the fishing net were analyzed by the dynamic response numerical mode with a new type of mooring. The purpose of the current study was to provide a basis for the optimization of structure shape, the matching of floating body, and the counterweight of artificial floating reef. Full article
