    In recent, industrial behavior by humans has caused heavy coastal erosion, and the global warming is deteriorating the coastal safety. Therefore, the research on safety of a coastal dike and a seawall is becoming very important, and Ioroi, et al. presented two methods for predicting the suction rates of backfilling materials from those bodies because the main reason why those in the shallows are broken by small waves is the suction. In this paper, the authors improve their methods in order to raise the accuracy and consider the influence of uniformity coefficient and dry density of backfilling materials to the suction.

    Strategic reverse logistics management is a key driver of sustainability in supply chains, where challenges in recyclable waste must be aligned with transportation systems to achieve optimal outcomes. A systematic review using the PRISMA methodology was conducted in December 2024 by searching Scopus, Google Scholar, and Thai Journals Online to examine the global research landscape and the strategic approaches applied in reverse logistics for recyclable waste and transportation. Analysis of 32 publications shows a steady rise in research, with most studies in Asia and dispersed across multiple journals, reflecting the field’s multidisciplinary nature. Four strategic approaches were identified. Model-driven approaches demonstrate strong capability through mathematical, computational, conceptual, and hybrid models, achieving reductions of 44% in climate impacts and 34% in costs. Technology-driven approaches contribute innovations to enhance battery transport safety. Exploratory approaches reveal contextual policy gaps and financial limitations. Hybrid approaches can improve efficiency and reduce CO<inf>2</inf> emissions. The future development of hybrid approaches still offers substantial room for broader application and deeper integration. This review supports the development of more effective systems, policies, and future research.

    Evaluation method of suction rate of backfilling materials from a coastal dike or a seawall

    Evidence shows that coastal dikes and seawalls could be damaged or destroyed by coastal scours and the suction of backfilling materials. As the impacts of coastal erosion and global warming become severer, it is necessary to be able to predict the suction rate of backfilling materials from underneath a dike or a seawall with sufficient accuracy. Therefore, this research paper proposes a method that can predict the suction rate of backfilling materials from a dike or a seawall. The findings show that the estimates of the suction rate using the proposed method were very similar to the measured field data. This fact indicates that the proposed method can predict the rate of suction with sufficient accuracy. Copyright © 2014 by the International Society of Offshore and Polar Engineers (ISOPE).
