Special Issue Information

Dear Colleagues,

Coastal areas represent one of the most vulnerable environments worldwide due to their high population densities and the pressure of human activities; sea level rise and increases in stormy weather due to climate change are expected to increase coastal flooding and intensify the frequency and magnitude of coastal impacts, posing a threat to coastal communities. The population exposed to coastal flooding is predicted to increase to up to 1.52–3.65 million by the end of the century. Meanwhile, there are also many ports and coastal and marine infrastructures that also place tremendous pressure on coastal and marine environments and their management. It is important, therefore, to strive for improved coastal management and marine environmental sustainability.

  • We invite you to submit your latest research works on subjects including, but not limited to:
  • Environmentally friendly structures, coatings, construction technologies, and management;
  • Environmentally friendly water quality inspection technology;
  • Environmentally friendly soil inspection techniques;
  • Foundations or structures suitable for soft soil;
  • Utilization technology of dredged silt;
  • Coastal and offshore energy systems;

Urbanization and land development in Asia, including Malaysia, have led to an increase in offshore sand mining activities, leading to significant environmental and social issues. Excessive sand extraction disrupts the ocean system equilibrium, necessitating sustainable management strategies. This study examined Malaysian offshore sand mining practices to recommend sustainable management approaches to be adopted. Using case studies involving interviews and document analysis, data were collected from 34 participants from six federal and state government departments, business owners, technical agencies, and community groups (including environmental non-governmental organizations from environmental action and consumer rights). The thematic analysis conducted in the case study revealed the need for six key strategies for sustainable management: (1) institutional strengthening, (2) adopting flexible technologies, (3) implementing comprehensive policy measures, (4) fostering stakeholder engagement, (5) capacity building, and (6) enhancing monitoring and enforcement. This study bridges the theoretical gap in sustainability management of offshore sand mining by examining the governance challenges faced and proposing strategic policy enhancements. This offers practical implications for designing policies that strengthen regulatory frameworks and improve mechanisms for sustainable development. Ultimately, this study underscores the importance of understanding management and policy structures and their implications for driving sustainable transformation in regional contexts. Hence, it offers a valuable planning and management framework for authorities, enabling effective and timely decision making in managing offshore sand mining in Malaysia. Full article

Large storage tanks situated in coastal areas are vulnerable to environmental hazards, with earthquakes being one of the most destructive forces threatening their structural safety. Additionally, differential settlement can significantly alter conditions in the tank, including the inclination, thereby changing the direction of external applied excitation forces and affecting the liquid sloshing response. To investigate the coupled effects of structural settlement and external excitation, model tests were conducted in series to analyze liquid sloshing behavior in a tilted tank subjected to harmonic excitation. The results revealed that the liquid response under combined environmental loads displayed distinct characteristics compared with that under single excitation. While the inclination angle had minimal influence during the unstable sloshing stage, it became crucial during the stable stage, particularly for third-order resonant responses, leading to intensified sloshing. More specifically, as the tilt angle of the storage tank from 0° to 8°, the steady-state wave height at third-order resonance increased by approximately 69%. This highlights the amplified risks to the structural stability and safety posed by differential settlement. Furthermore, variations in steady-state wave heights due to differential settlement conditions were investigated. The water level elevation along the tank walls varies as the inclination angles increase, which leads to potential risks to the stability of liquid storage under forced motion, especially under symmetric structural designs, and increases the likelihood of structural instability, oil spills, and other coastal disasters. These results provide valuable insights into the safety risks and sustainable utilization of coastal infrastructure, serving a basis for assessing and mitigating the risks associated with structural settlement and seismic excitations.

Chloride ion erosion in seawater is a major cause of durability damage to reinforced concrete structures. Most of the currently used anti-corrosion coatings are organic polymer coatings, which are prone to aging and peeling off and polluting the environment. Inspired by the underwater adhesion behavior of mussels, a green substance-tannic acid (TA) is found and used as the main material of anti-chloride coatings. Three assembly methods of green concrete chloride-resistant coatings fabricated by the oxidative self-polymerization of tannic acid, coordination-driven one-step assembly and multistep assembly of tannic acid (TA), and trivalent iron cation (Fe(III)) on a concrete surface are proposed. Compared to the other two assembly methods and existing coatings, the one-step assembly of the TA and Fe(III) coating was recommended to be the first choice because of its good continuity; shortest time-consumption (just 10 min); lowest price (only one-third of epoxy coating); and the best chloride-resistant effectiveness per unit thickness reaching 52.17%, far better the multistep assembly method and the oxidative self-polymerization method by 12.67% and 2.42%, which is 79-times higher than that of epoxy resin A. This study offers a TA-based concrete coating fabricated by the one-step assembly method with an excellent anti-chloride performance and cheap price, which is promising for a wide range of applications for the chloride-resistant corrosion protection of steel-reinforced concrete in seawater environments.
