Special Issue Information

Dear Colleagues,

We are delighted to invite contributions to a Special Issue on "Critical Issues in Ocean and Coastal Engineering". Ocean and coastal environments play a pivotal role in shaping our planet and are of paramount importance for both natural ecosystems and human societies. In recent years, the challenges faced in these areas have become increasingly complex and pressing due to factors such as climate change, rising sea levels, extreme weather events, and growing coastal populations.

This Special Issue aims to bring together cutting-edge research and insights from experts in the field of ocean and coastal engineering. We seek to explore the most critical and contemporary issues facing coastal and marine environments, with a focus on innovative solutions, sustainable practices, and interdisciplinary approaches. We invite researchers, engineers, and scientists to contribute their original research, review articles, and case studies to foster a deeper understanding of these challenges and to pave the way for informed and effective strategies.

Topics of interest for this Special Issue include but are not limited to:

  • Coastal erosion and shoreline management;
  • Sea-level rise adaptation and resilience;
  • Coastal infrastructure and maintenance;
  • Sustainable coastal development;
  • Marine renewable energy systems;
  • Coastal and ocean modelling;
  • Innovative coastal and ocean engineering;
  • Disaster risk reduction in coastal regions;
  • Eco-engineering in coastal zones;
  • Social and economic impacts of coastal engineering projects.

We encourage contributions that offer new perspectives, innovative methodologies, and practical insights into addressing the critical issues faced by ocean and coastal engineers today. Your work can contribute significantly to advancing our knowledge and facilitating the sustainable development and protection of these vital environments.

We look forward to receiving your contributions and fostering an enriching dialogue on the critical issues in ocean and coastal engineering. Together, we can strive for a more resilient, sustainable, and harmonious coexistence with our oceans and coastal regions.

We eagerly anticipate your valuable contributions to this Special Issue.

It is crucial for reef revetments to respond dynamically to rigorous wave actions for structural stability and safety. A comprehensive analysis of the interaction between the wave force and wave overtopping in a reef revetment project was conducted based on wave flume experiments. This study explored how wave conditions, the water depth along the reef flat, and the proximity of the reef edge to the revetment project influenced wave overtopping and wave force patterns. The results indicate that as the incident wave height, period, and water depth along the reef flat increased, the average wave overtopping within the revetment project also increased. Additionally, higher levels of average wave overtopping occurred with the decrease in the distance between the revetment project and the reef edge. The peak wave force on the seawall of the revetment project was studied in response to various factors, including wave period, wave height, water depth along the reef flat, and distance to the reef edge. The changes in the maximum wave force reflected those of the average wave overtopping, with a strong linear correlation. The quantitative relationship between these variables was determined, and the wave forces on the seawall could be indirectly estimated using the average wave overtopping volume. This study provides an efficient methodology for assessing the dynamic attributes of revetment projects and the disaster risk of these structures. Full article

The construction of coastal infrastructure alters the natural hydrodynamics, leading to irreversible changes in coastal morphology. Furthermore, there has been an increasing concern about global climate change in recent years, which requires examining how climatic shifts impact the mechanisms that govern oceanic processes, the trends in morphological changes, the extent of the impacts, and the corresponding weightings assigned to coastal infrastructure. This study aims to assess the impacts of climate change on the wave distribution and coastal morphology around the two breakwaters perpendicular to the shoreline of Hsinchu Fishery Harbor in Taiwan at the end of the 21st century. The findings reveal that, by the end of the century, during extreme climatic events, such as typhoons (increasing the maximum wind speed and extreme sea levels), the wave heights around the Hsinchu Fishery Harbor, compared to the present day, may increase by 5.94% to 81.25%. Regarding the potential coastal morphological changes, erosion trends are evident around the harbor, but there is a pronounced tendency toward accretion in the sheltered area. The impact range and weightings of the Hsinchu Fishery Harbor breakwaters under climate change on coastal morphology were then determined based on historical bathymetric data and simulated bathymetric changes using the empirical orthogonal function (EOF) method. Under different-intensity climate change scenarios, the EOF analysis indicates no significant differences in the impact range and weightings on coastal morphological changes. In light of the analysis results, it is evident that structures have a much more substantial impact on coastal morphological change than climate change does. Full article
