Summary: This study investigated sediment resuspension under hydraulic disturbances by sampling sediment columns from different points in Chaohu Lake and conducting laboratory experiments. The results showed that the response of the sediment surface to hydraulic disturbances varied depending on the strength of the disturbance and sediment surface shear stress. The plankton layer and the new sediment layer were found to play important roles in sediment resuspension.

Summary: This study quantified the effect of hydraulic disturbances on sediment phosphate release in a representative shallow lake in China. The results showed that the release rate of phosphate increased with the intensity of hydraulic disturbances, and varied among different regions. These findings have important implications for water quality assessment and pollutant management in shallow lakes.

Summary: Based on the study, resuspension is a crucial process for the release of endogenous pollution from shallow lakes. Sediment elution technique can effectively remove fine particle sediment and inhibit the release of ammonium nitrogen and total dissolved phosphorous. Moreover, it alters the microbial community structure and decreases the concentration of nitrogen and phosphorus pollutants in pore water.

Summary: Sediment-water interfaces are important in lakes and are connected to various environmental and ecological issues. Waves induced by wind can lead to secondary pollution through sediment resuspension. A coupled model was developed to examine sediment resuspension and phosphorus release, considering different sediments with varying adsorption-desorption capabilities. The study found relationships between wind speed, wave characteristics, sediment distribution, and phosphorus concentration. Higher wind speeds were negatively correlated with sediment desorption release. When sediment resuspension occurs under low or moderate wind speeds, there is a sudden increase in phosphorus concentration in the overlying water, hindering diffusion. Phosphorus release is concentrated in a small region, resulting in rapid changes in the water environment.

Summary: We examined the factors of warm air temperatures, high solar radiation, and weak wind speeds in causing hypoxia in a shallow lake during a heat wave. By simulating dissolved oxygen concentrations in the lake's bottom water, we compared the concentrations in 2022 with the average concentrations of the past 30 years. Our findings showed that wind speeds had the greatest impact on hypoxia occurrence. Insufficient convection led to hypoxia when wind speeds were low, but there was no hypoxia when the wind speed matched the 30-year average. However, if solar radiation and air temperatures matched their respective 30-year averages, hypoxia did not occur even with low wind speeds. Therefore, we concluded that the combination of weak winds and either high solar radiation or air temperatures induced hypoxia during the 2022 heat wave.

Summary: This study assessed microplastic pollution in tropical shallow lakes and found different types and colors of microplastics in lake sediments. The results showed that environmental factors influenced the concentration of microplastics, but there was only a small difference between different regions. The study also suggested that pollution from sanitation, sewage effluents, and solid waste may be the main factors contributing to microplastic contamination.

Summary: The study demonstrated that adding phosphorus adsorbents can effectively reduce phosphorus release in sediment cores from a shallow eutrophic lake exposed to anoxic and sediment resuspension conditions. Both CFH-12 (R) and Phoslock (R) showed high efficiency in phosphorus removal, making them promising agents for lake restoration under such circumstances. Further research on the performance of CFH-12 (R) under different factors is needed.

Summary: This study investigates the drivers of water column light attenuation (K-d) in Lake Fil, Denmark, after its re-establishment in 2012. The findings show that higher wind speed increases K-d on the same day and the next day, with significant influence from wind direction. The fast variations in K-d highlight the importance of wind on the light climate and subsequent biological elements in shallow lakes.

Summary: Although cyanate concentrations in estuarine systems have not been studied, this research examines the variations and sources of cyanate in the Lafayette River. The results indicate that cyanate concentrations are correlated with chlorophyll biomass, biomass degradation, and sediment resuspension events. Algal decomposition is suggested as a source of cyanate, and bottom water cyanate concentrations are related to wind-induced sediment resuspension. Additionally, cyanate concentrations in sediment pore water vary between years. The study also confirms that cyanate is an early product of organic matter decomposition and that production and uptake of cyanate are tightly coupled with a high affinity of microbes for cyanate.

Summary: Top-down surface mixers are effective in preventing stratification, controlling cyanobacteria, and limiting sediment release of soluble manganese in drinking water reservoirs. However, their limited range of influence leaves a majority of the reservoir exposed to potential issues such as stratification, anoxia, and internal loading of inorganic nutrients and metals.

Factors such as seasonal mixing and near-bottom anoxia influence arsenic uptake. Monitoring and risk assessment of arsenic contamination should focus on shallow zones in lakes.

Summary: In this study, the researchers used acoustic Doppler current profilers to investigate the mechanisms of water and sediment transport in Onsan Bay. They found that water circulation in the bay was influenced by freshwater discharge from the river and exchange with the open sea, as well as by wind-induced currents. The sediment transport within the bay was mainly controlled by estuarine residual circulation, and frequent resuspension events contributed to an increase in sediment concentration. Considering the prevailing winds in the area, sedimentation is expected to persist in Onsan Bay.

Summary: Research indicates that bubble-plume diffusers introduce mixing energy and subtle changes in water quality and thermal structure in lakes and reservoirs, necessitating consideration of the complex interaction between plumes and reservoirs. Wind-driven internal seiches are found to be the primary driver of internal circulation in reservoirs, with oxygen exchange controlled by internal-seiche driven transport through basin constrictions and plume-induced circulation.

Summary: Mediterranean wetlands are expected to experience amplified water level fluctuations due to global climate change, which will impact phosphorus dynamics and greenhouse gas emissions. While desiccation may increase CO2 emissions and inundation decrease cumulative CO2 emissions and N2O emissions while increasing CH4 emissions, there is still a lack of knowledge on the net effect of water level fluctuations on greenhouse gas emissions. Further research is needed to assess the role of these ecosystems as a source of greenhouse gases and as a feedback mechanism for global warming.

Summary: Temporary Mediterranean wetlands exhibit both intra and interannual variations in environmental conditions, impacting the structure and dynamics of aquatic communities. Chlorophyll-a concentration, Secchi depth, total nitrogen concentration, wetland area, and depth were found to have significant influences on zooplankton community, leading to species replacement patterns. Optima and tolerance of zooplankton species were identified based on their positions within a CCA diagram, enabling the grouping of species along the hydroperiod. Monitoring of zooplankton community and environmental conditions is crucial to assess the potential impacts of anthropogenic activities on these unique and endangered aquatic ecosystems in the future.
