Summary: Stream nitrate nitrogen (NO3) concentrations and concentration-discharge (C-Q) relationships in the Spree catchment were investigated to understand their long-term variability and response to climate change. The study revealed that while nitrate inputs were decreasing, stream NO3 concentrations varied at different spatial scales and showed seasonal differences. The upper catchment, with a high proportion of farmland, had high levels of stream NO3 concentration, while the mid-and lower-catchment areas showed a positive correlation between stream NO3 concentrations and streamflow. The stream NO3 concentrations were also affected by drought conditions and hydrological connectivity.

Summary: A recent drought in Southeast Brazil affected the water supply to Sao Paulo megacity, raising concerns about the impact of climate change on water resources. The study found that changes in rainfall are the key factor influencing the water budget. Higher carbon dioxide concentrations reduced evapotranspiration but increased discharge. These findings have significant implications for water management.

Summary: Rivers play a crucial role in the transport and retention of macroplastics in the environment. Understanding these processes is essential for determining the fate of macroplastic in the environment. A study conducted during a flood event found that smaller macroplastics were flushed away from riverbanks, while larger soft plastic fragments and wet tissues were deposited. These findings suggest that plastic deposition and remobilization processes differ between extreme flood and normal conditions, contributing to a better understanding of macroplastic fate.

Summary: Climate change is causing more frequent extreme weather events, such as floods, droughts, and heatwaves, which are impacting water supply systems globally. Water agencies and utilities need to develop resilient and adaptable systems to cope with these challenges. Case studies, like the one on water quality and supply management in New South Wales, demonstrate the importance of effective water treatment processes and collaboration among local governments to ensure a secure and reliable water supply during extreme weather events.

Summary: This study examined the impact of the 2018 drought on the water quality of the Rhine and Meuse rivers in Western Europe, focusing on parameters like water temperature, salinity, and select pharmaceuticals. The results showed a general deterioration in surface water quality due to low flow and high temperatures, with significant increases in water temperatures and salinity levels, and slight increases in some pharmaceutical concentrations. The main factors contributing to the decline in water quality were limited dilution from point sources and salinity intrusion in the lower part of the Rhine-Meuse delta.

Summary: The analysis of the water balance in the southwestern United States from 1900 to 2018 revealed that during the turn-of-the-century drought, warm season soil moisture and runoff were at their lowest levels, with increased temperatures identified as a significant factor driving these conditions. However, during the cool seasons and the water year of the drought period, soil moisture and runoff did not show extremely dry conditions despite higher temperatures compared to the rest of the period between 1900 and 2018.

Summary: Global water scarcity is influenced by both water quantity and quality issues, and increasing investment in clean water technologies is crucial to reduce the number of people affected. Considering water quality factors can raise the percentage of population suffering from severe water scarcity in heavily affected regions. Excessive water withdrawals and polluted return flows contribute to water scarcity and degraded water quality in severe water scarcity regions. Expanding desalination and treated wastewater reuse can effectively alleviate water scarcity levels in Asia, but potential side effects must be carefully considered.

Summary: To achieve global food security, sustainable water use in irrigated croplands is essential. Crop nitrogen uptake needs to increase by 20% while irrigation withdrawals should decrease by over one third for sustainable water use. Intensification of currently irrigated croplands may lead to production decrease in some regions, requiring further research to assess suitable water management options.

Summary: This study reviews the main indicators of eutrophication in global freshwater lake basins, which include not only water quality constituents but also the sources, biogeochemical pathways, and responses of nutrient emissions. The authors propose a new causal network framework that highlights complex interrelationships among the indicators and provides a holistic perspective of eutrophication dynamics in freshwater lake basins. The study indicates a need for more comprehensive indicators to guide the global expansion of water quality monitoring networks and support integrated assessments to manage eutrophication.

Summary: Climate change and extreme weather events pose serious challenges for water management due to their impacts on water resources availability and water quality. This review assesses the impacts of these events and climate change on river water quality and identifies the key responses and driving mechanisms. The findings show that river water quality generally deteriorates under droughts, heatwaves, rainstorms, floods, and long-term climate change, while improvements or mixed responses are also reported. The driving mechanisms include hydrological alterations, rises in water and soil temperatures, and interactions among hydroclimatic, land use, and human drivers.

In this study, researchers proposed a methodology to test and benchmark ML algorithms using artificial data generated by physically-based hydrological models. They found that deep learning algorithms can correctly identify the relationship between streamflow and rainfall in certain conditions, but fail to outperform traditional prediction methods in other scenarios.

Summary: High-resolution climate data is crucial for predicting regional climate and water environment changes. In this study, a two-step downscaling method was developed to enhance the spatial resolution of GCM data and improve the accuracy for small basins. The method combined medium-resolution climate data with high-resolution topographic data to capture spatial and temporal details. The downscaled climate data were then used to simulate the impacts of climate change on hydrology and water quality in a small basin. The results demonstrated the effectiveness of the downscaling method for spatially differentiated simulations.

Summary: Precipitation over the Tibetan Plateau is influenced by systems such as the Asian monsoons, the westerlies, and local circulations. The Indian monsoon, the westerlies, and local circulations are the main systems affecting precipitation over the entire Tibetan Plateau. The East Asian summer monsoon primarily affects the eastern Tibetan Plateau. The Indian monsoon has the greatest influence on precipitation in the southern and central grid cells, while the westerlies have the greatest influence on precipitation in the northern and western grid cells. Local circulations have the strongest influence on the central and eastern grid cells.
