Summary: This study applies a two-dimensional, non-linear, finite difference, hydrodynamic model to investigate the changes in tidal current asymmetries along the San Pedro channel. The results show that after reconnecting the main channel to a previously desiccated tidal lagoon, the current asymmetries become stronger and directed towards ebb. The influence of upstream intertidal flats on tidal current asymmetries and residual currents is found to be more pronounced during spring tides.

Summary: Reclamation of tidal flats is a common method used in coastal areas to expand land area and develop the economy. This study investigates the impacts of reclamation on tidal and suspended sediment dynamics using numerical modeling in the Oufei tidal flat at the Wenzhou coast. The results show that reclamation reduces the tidal flat area, weakens tidal currents, and reduces suspended sediment concentration. The construction of the Oufei dike also alters sediment circulation and enhances landward sediment transport inside the estuary. The findings of this study can be used as a reference for analyzing suspended sediment transport in other sites affected by tidal flat reclamation.

Summary: The tidal channels and mudflats in estuarine wetlands are ecologically important for aquatic organisms and nutrient exchange. This study established a geomorphological model to understand their dynamics. The model was validated in the Tanshui River estuary, and findings revealed that soil properties and erosion rate were the most influential factors. The asymmetry between ebb and flood tides contributed to the maintenance of tidal channels. River floods transported sediment and accelerated wetland siltation. Reduced tidal range and suspended sediment input were effective measures to prevent channel deposition.

Summary: This study evaluated the response of cordgrass seed bank dynamics to changing physical disturbance at tidal flats, revealing that wave disturbance reduced the persistence of seeds on the surface, while amplified sediment disturbance lowered the persistence of both surface and buried seeds. This indicates that increasing storminess and associated sediment variability under climate change threatens seed bank persistence in tidal flats.

Summary: Coastal tidal flats are important ecosystems, but they are highly vulnerable to tidal dynamics, sea-level rise, and human activities. This study examined the hydrodynamics, sediment transport, and morphological changes on two tidal flats in the Yellow River Delta with different tidal regimes. The results showed that longer inundation periods under diurnal tides led to more sediment deposition, while semi-diurnal tides resulted in increased wave impact and tidal flat erosion due to lower water depths. These findings highlight the joint role of tidal regime and powerful waves in controlling sediment availability and tidal flat evolution. This has implications for managing erosion and restoring vegetation in the Yellow River Delta.

Summary: The study found that flow and SSC surges occur during periods of very shallow water on tidal flats, with flood surges in the lower intertidal flat being erosive and leading to local resuspension, while weaker surges in the middle intertidal flat do not resuspend bed sediment. Surges on the lower intertidal flats contribute up to 25% of onshore-suspended sediment flux during flood tides, despite lasting only 10% of the flood duration.

Summary: This study used the waterline method to construct digital elevation models (DEMs) of tidal flats around Tongzhou Bay on the Jiangsu coast, and analyzed the topographic evolution characteristics. The results showed that the tidal flats were overall in a state of deposition, the reclamation activities affected the topography but had a rapid recovery, the reclamation project directly influenced the erosion and siltation distribution, and the sandbars in Tongzhou Bay generally had a southward-moving trend. This study provides a remote sensing solution for the topographic evolution of large tidal flats under the influence of human reclamation activities.

Summary: The study investigated the spatial and vertical distributions and compositions of microplastics (MPs) in tidal flat sediments along the west coast of Korea. The abundance of MPs in surface and core sediments ranged from 20 to 325 and 14 to 483 particles per 50 g dry weight, respectively. Polypropylene (51%) and polyethylene (36%) were the most dominant MPs with a size <0.3 mm, and mostly appearing as fragments and fibers. The abundance of MPs in sediments has increased rapidly since the 1970s but recently showed a slight decrease. Scanning electron microscope analysis revealed that the MPs in tidal flats were highly weathered mechanically and/or oxidatively. This study provides valuable baseline data on the distribution of MPs in tidal flats.

Summary: Repetitive loads lead to fatigue cracking failure of concrete pavements. This study investigated the enhancement of mechanical strength and flexural fatigue resistance of normal concrete by utilizing natural rubber latex (NRL). The effect of water to cement (w/c) and dry rubber to cement (r/c) ratios on compressive and flexural strengths as well as flexural fatigue behavior was examined. It was found that higher r/c ratios resulted in lower compressive strength but higher flexural strength. Concrete modified by NRL had lower plastic deformation and higher fatigue life compared to normal concrete. The NRL-concrete pavement with optimized r/c ratio had a thinner thickness and reduced operational cost.

Summary: The study focused on heavy metal pollution in the green vegetation of a suburban industrial area in Tuokexun County, Xinjiang, China. The results showed that the overall level of heavy metal pollution in the soil was minor, with mercury (Hg) being the most severe contamination, likely caused by human activities. The composition of heavy metal elements in trees was more stable compared to grass and shrubs, with varying concentrations across different vegetation. Shrubbery was found to be the most effective in heavy metal restoration, and there were disparities in heavy metal enrichment among different vegetation types.

Summary: Plastic pollution has significant environmental impacts, largely due to chemical additives. However, the behavior of plastic additives in marine environments is not well understood. A marine deployment experiment was conducted to investigate the effects of weathering on the extractables profile of four types of plastics in New Zealand over a period of nine months. The concentration of additives in polyethylene and oxo-degradable polyethylene was strongly influenced by artificial weathering, while polyamide 6 and polyethylene terephthalate showed minimal change. These findings emphasize the importance of considering leaching and weathering effects on plastic composition when assessing the potential impact and risk of plastic pollution in receiving environments.

Summary: Few studies have examined the impact of urbanization and meteorological events on microplastics discharged into the sea through rivers. Surface water samples were collected from two Lebanese rivers, with differing degrees of urbanization, during dry and wet periods. The results showed that the most industrialized river had a significantly higher abundance of microplastics compared to the less-industrialized river. There was also a correlation between particle contamination and the season at each site, with microplastic concentrations highest on the first day of the wet season. These findings highlight the importance of considering meteorological events in accurately assessing plastic pollution influx into coastal waters.

Summary: This study investigated the variability in phytoplankton functional structure using a trait-based approach and explored the relationship between species traits and environmental factors, as well as their impact on ecosystem functioning. The results revealed that morphological traits, temperature, and ammonia played a decisive role in the seasonal succession of phytoplankton species. It was found that certain traits favored higher biomass production but might hinder energy transfer efficiency. The strong correlation between environmental variables and phytoplankton functional structure supports the practical implementation of a trait-based approach in studying phytoplankton community dynamics under different environmental conditions.
