Summary: This study investigated the water quality patterns and influencing factors in China's largest river, the Yangtze River, finding that water quality was mainly influenced by land use, hydrology, and climate. Decision-makers and regulators of large river basin management should develop programs that consider both human and natural drivers for water quality conservation.

Summary: Studies in the Colorado River Basin have found that warming has caused declines in streamflow since 2000, especially in the Upper Basin. However, it is uncertain if increased precipitation variability could outweigh the effects of future warming. To address this, a model framework was used to project streamflow across the entire basin, showing significant declines in streamflow due to warming and decreased precipitation. The spatial analysis provided actionable information for water management in the basin.

Summary: This article discusses the decrease in river temperature in the heavily industrialised area of Upper Silesia Region in Poland and attributes it to the construction of modern sewage treatment plants and restrictions on water discharge from closed coal mines. The study reveals a significant average annual decrease of 0.8 degrees Celsius in river temperature during the period of 1961-2015, with the most notable drops occurring in the winter season.

Summary: Soil moisture-atmosphere coupling induces non-linear warming via the 'warmer climate - drier soil' feedback, exerting an accelerating effect on global warming and extreme high temperatures. The projection shows that SA-driven warming will exceed 0.5°C over extratropical landmasses by the end of the 21st Century, increasing the likelihood of extreme high temperatures.

Summary: The importance of soil moisture in triggering river floods is increasingly recognized. However, groundwater from the deeper, saturated zone plays a significant role in river flow and flooding, although its effects are not well understood. Analyzing hydroclimatic records of North American watersheds from 1981 to 2018, it is found that baseflow, which is groundwater-sustained river flow, influences the magnitude of annual flooding at different timescales. Floods are mainly caused by the combination of high precipitation and baseflow, with flood magnitudes more closely related to changes in baseflow than in soil moisture and short-term extreme precipitation. Additionally, long-term trends in flood magnitude and decadal variations align more with groundwater storage and baseflow trends rather than changing precipitation extremes and soil moisture, indicating the importance of groundwater in shaping North American river floods.

Summary: This study examined the effectiveness of forested riparian buffers as a climate adaptation strategy in the Meramec River basin in eastern Missouri. The results suggest that riparian buffers can mitigate increases in water temperature, but do not significantly impact discharge patterns. Additionally, adding riparian buffers is projected to reduce the impacts of climate change on Smallmouth Bass.

Summary: Climate warming may increase the threat of antibiotic resistance genes (ARGs) to the environment and human health. Gradually elevated water temperature was found to reduce ARG diversity but increase ARG abundance in the Yellow River. Certain high-risk ARGs significantly increased with elevated water temperature, implying an increased antibiotic resistance risk under climate warming. Our study provides a novel approach to predict and control ARGs in water environments under climate warming.

Summary: This study examines the implication of considering a semi-distributed recharge in a lumped parameter model through multiple hydrological model calibrations and focuses on the uncertainty caused by the model structure. The results suggest that considering a semi-distributed recharge can improve the performance of hydrological models in forest-dominated karst areas, but it may not be applicable to all karst environments.

Summary: The Tigris-Euphrates dryland river basin has experienced a decline in terrestrial water storage from April 2002 to June 2017. Climate variations and direct human interventions account for 61% and 39% of the negative trend, respectively. Interannual climate variability and decadal climate change contribute to the negative trend, with the former playing a slightly larger role.

Summary: Aggregates, as the most extracted material resources, are facing shortages and negative impacts. Recent investigations on sand and gravel issues are often ambiguous in definition or use over-simplified accounting methodology. This study conducted a detailed literature investigation and established a systematic accounting framework to understand the social metabolism of aggregate resources in China. The results show a relative decoupling of aggregate inflows and stocks from economic growth, with a shift towards manufactured aggregates as the dominant supply. The study highlights the importance of establishing a well-functioned circular system for the sustainable development of the aggregate industry.

Summary: Coastal rivers are a major contributor of anthropogenic nitrogen loads to coastal waters. Accurate identification of nitrogen sources is crucial for effective pollution control strategies. This study used stable isotopes and water quality parameters to identify nitrogen dynamics and sources in two coastal rivers. The results showed that soil and domestic wastewater, as well as aquaculture tailwater, were the major sources of nitrogen pollution. Combining stable isotope analysis with the APCS-MLR model provided reliable and cost-effective results for nitrogen source identification. The study emphasizes the importance of soil nitrogen management and aquaculture tailwater treatment in coastal river pollution control.

Summary: The response of soil microbes to heavy metal pollution is important in assessing soil health and ecological risks associated with heavy metal contamination. In this study, the effects of long-term exposure to multiple heavy metals on soil microbial communities were examined. It was found that protist diversity increased while bacterial diversity decreased at high pollution sites compared to low pollution sites. The bacteria community also showed low functional diversity and redundancy at highly polluted sites. Predatory protists in Cercozoa were found to be the most sensitive to heavy metal pollution, while photosynthetic protists showed tolerance. This study highlights the potential of certain bacteria and photosynthetic protists for bioremediation and restoration of heavily contaminated industrial sites.

Summary: This study investigated the formation of new soils after the eruption of Mount Tambora 200 years ago. The results showed that the new soils were dominated by easily weatherable minerals and had high potential nutrient reserves. The formation rate of the new soils ranged from 1.2 to 5.3 mm/year, and they accumulated significant stocks of organic carbon and nitrogen, indicating a rapid recovery of soil functions to support agricultural production after the volcanic eruption.

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.
