Special Issue Information

Dear Colleagues,

The accurate and cost-effective prediction of hydrodynamic and environmental parameters is essential for optimizing marine resource management, assessing environmental risks, and developing effective policies. However, the destructive impact of climate change on the coastal environment and marine ecosystems worldwide poses a significant challenge. This Special Issue aims to showcase the latest improvements in numerical simulation and the application of this in coastal environments and marine waters to address the pressing challenges of the impacts of climate change. The objective of this Special Issue is to disseminate new knowledge of the prediction and characterization of hydrodynamic and environmental parameters using advanced simulation techniques to mitigate the destructive impact of climate change on marine resources and ecosystems. Contributions to this Special Issue can range from novel models for hydrodynamic parameter estimation to the development of innovative simulation techniques related to ocean engineering and marine environment monitoring. In summary, this Special Issue presents a unique opportunity to advance our understanding of how simulation techniques can help us address the pressing challenges facing marine resources caused by climate change and pave the way for the use of more sustainable and efficient practices in coastal and ocean engineering. The Special Issue invites contributions which focus on the following topics: Advanced modeling for coastal and offshore structure; numerical simulation of extreme ocean event; analysis of climate change impacts on coastal engineering; marine pollution detection and management; and the development of models for coastal hazard assessment.

The Bonnet Carré Spillway is a large flood control structure that diverts Mississippi River floodwaters into Lake Pontchartrain and the Mississippi Sound to prevent flooding in southern Louisiana and New Orleans. When operating at full capacity, the Spillway releases water at a rate of 7080 m3/s. Spillway openings regularly last a month or more. The enormous amount of freshwater that is diverted through the Spillway impacts salinity and nutrients in the Mississippi Sound. The objective of this research is to use a hydrodynamic model to simulate the impact of Bonnet Carré Spillway openings on the salinity of the Mississippi Sound over multiple years. Specifically, four hypothetical simulations of Spillway openings are compared to simulations during the same time when the Spillway is closed. The results show by how much, for how long, and where salinity is impacted in the estuarine system. The maximum difference in salinity at any given location over the mapped dates between the non-opening and hypothetical opening scenarios varies between 22 and 30 in each year. Differences in salinity between the opening and non-opening scenarios begin to decline in the study area approximately 18 days after Spillway closure. Decreases in salinity in Lake Borgne persist over a year. The Bonnet Carré Spillway affects salinity mostly in Lake Borgne and along an east/west ribbon that embraces the Mississippi coastline. Decreases in salinity caused by Spillway openings are seen up to 200 km east of the Spillway. These results are important for planning management strategies for estuarine resources during Spillway openings. Full article

The vulnerability to coastal disasters resulting from storm surges and wave overtopping (WOT) during typhoon intrusions is significantly escalating due to rising sea levels. In particular, coastal seawalls constructed along the coast through engineered assessments are experiencing an increase in the frequency of WOT and associated flooding in proportion to the reduction in freeboard due to rising sea levels. This study employed a unified modeling system that combines an empirical formula for estimating WOT volumes with a numerical model simulating tides, waves, and storm surges. The analysis was conducted across the Northwest Pacific (NWP) Ocean, encompassing coastal seawalls and terrestrial regions, using an integrated seamless grid system, which utilized ADCIRC + SWAN + EurOtop, for the present day, 2050, 2070, and 2100 to investigate how vulnerability to WOT changes with sea level rise. The maximum envelope of WOT inundation results for three historical and two 100-year return period synthetic typhoons confirms that vulnerability to WOT intensifies with rising sea levels. The single-process integrated model applied in this study can serve not only for long-term coastal seawall protection design but also for the short-term early warning system for storm surges and WOT, contributing to immediate preparedness efforts.

The use of the heavy hammer compaction method can enhance the bearing characteristics of underwater rubble-mound foundations. This is crucial to ensure the safety and stability of port and coastal engineering projects. In the present work, a combination of image-recognition technology, 3D laser scanning technology, a discrete element numerical simulation, and a field test was first utilized to establish riprap particles and reconstruct a discrete element numerical model of a rubble-mound foundation, and then the effects of various influencing factors on the bearing characteristics of the rubble-mound foundation were studied. The main conclusions are as follows. (1) The load–settlement curve of the rubble-mound foundation can be divided into three stages: rapid growth stage, slow growth stage, and failure stage. (2) The ultimate bearing capacity of the rubble-mound foundation is positively correlated with the vibration time and vibration amplitude. The riprap particle size and the foundation thickness have negligible effects on the ultimate bearing capacity of the rubble-mound foundation. (3) When adjusting the vibration time, vibration amplitude, and foundation thickness, the settlement value of the rubble-mound foundation tends to increase as the compactness increases. On the other hand, the effects of factors such as the riprap particle size, riprap particle gradation, and vibration frequency on the compactness and settlement value of the rubble-mound foundation are less significant.
