Summary: A study has found that the location of river avulsions is controlled by multiple factors, including changes in valley confinement, flow deceleration or acceleration within the backwater zone, and the extent of flood-driven erosion upstream. These findings have important implications for predicting and mitigating avulsion hazards, as well as understanding the impacts of land use and climate change.

Summary: Climate change has a stronger impact on water yield compared to landuse change, while landuse change has a more significant effect on sediment yield. The conversion of rangelands to barren land is identified as a critical factor increasing sediment yield. The combined effects of climate and landuse change are projected to have the most significant impact on water balance in the future.

Summary: Humans have significantly disrupted the global sediment cycle, affecting river morphology and ecosystems. Based on satellite observations from 1984 to 2018, the RivSed database provides a spatially explicit view of river sediment, revealing declining trends in sediment concentration in 32% of US rivers. Most rivers show decreasing sediment concentration downstream, primarily due to large dams. Comparing observations with models, there are differences in longitudinal sediment concentration patterns. RivSed has important implications for river geomorphology and ecology, illustrating human impacts on US river corridors.

Summary: Sediment transport load monitoring is important in civil and environmental engineering fields. This study proposes estimation models for the suspended-to-total load fraction using dimensionless hydro-morphological variables, and reveals the relations between them using symbolic regression methods. Clustering analyses help identify the underlying relationships between variables. These models are practical and easy to implement in other suspended sediment monitoring methods.

Summary: Global compilations of river sediment loads show that mountainous areas contribute significantly to the sediment transported to the oceans. This study focused on estimating the contemporary sediment loads of 16 gravel bed rivers draining the Ecrins-Pelvoux Massif in southeast France. The results indicate a linear relationship between bed load fluxes at channel-forming flows and downstream increases in discharge, as well as a linear scaling of annual sediment loads with drainage area.

Summary: Vegetation plays a crucial role in riverine environments by influencing hydrodynamics and morphodynamics. This study derived analytical formulations to predict the thresholds for vegetation colonization based on flow velocity and Froude number, considering submergence conditions. The results highlight the importance of vegetation characteristics and flow regime in determining the thresholds, and provide insights for river restoration projects and understanding bio-morphological changes.

Summary: Bedload is difficult to measure and model, and its dynamics in most fluvial systems worldwide remain unknown. This study presents a global scale bedload flux model that predicts the distribution of water discharge, suspended sediment, and bedload, and analyzes the sensitivity of bedload predictions to various factors. The results show that river discharge and slope are the key drivers of bedload trends.

Summary: Temporary rivers in the Mediterranean region pose a challenge for environmental regulations, but there is a lack of comprehensive analysis of their ecological status and stressors. This study compiled data on 1504 temporary rivers in seven Mediterranean countries, finding that over 50% of the water bodies reached good or high ecological status. Land use intensity was found to have the overarching effect on the ecological status, and biomonitoring systems need to be updated for the specific situation of temporary water bodies.

Summary: Intermittent rivers are common in Europe, with increasing numbers of zero-flow days observed, particularly in southern Europe. Local catchment properties have a significant impact on the seasonal patterns of intermittence and zero-flow days. The SPEI is strongly related to the occurrence of zero-flow days at most stations, while there is a weaker dependence on large-scale circulation indices.

Summary: A simplified approach was developed to explore nutrient deliveries from watersheds to coastal zones, indicating that coastal morphology and hydrological conditions are key factors in eutrophication. Intervening in the agricultural system of upstream watersheds to reduce pollution is identified as the most effective control measure. Achieving a comprehensive understanding of river and coastal water degradation involves interdisciplinary collaboration and modeling approaches, promoting sustainable environmental choices for all citizens.

Summary: In vulnerable areas with frequent floods, participatory workshops have been proven to be highly effective in decision-making and integrated management. This paper examines Nature-Based Solutions (NBS) for flood risk mitigation and proactive adaptation in the Kalloni river basin in Greece, a highly flood-prone area. Using participatory methods and community-based approaches, stakeholders prioritized and evaluated NBS options based on sustainability at social, economic, and environmental levels. Small-scale mountainous dams, afforestation, and planting measures were found to be the most acceptable alternatives. Construction sites for gabion and wooden wall dams were selected based on examination of elevation models and estimated water and sediment flow. This study shows that NBS strategies, dependent on stakeholder involvement and government intervention, can drive sustainable change.

Summary: Research indicates that Mediterranean rivers will undergo significant changes in hydrological characteristics as climate change intensifies, posing a major threat to intermittent flow rivers and ephemeral streams. Over the next 100 years, a significant decrease in annual flow and an increase in extreme flood events are predicted for the Tsiknias River in Greece. The occurrence patterns of hyporheic and edaphic aquatic states are also expected to be affected due to climate change.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
