ClearLong-term variations in water discharge and sediment load of the Pearl River Estuary: Implications for sustainable development of the Greater Bay Area
This study examined long-term trends in water discharge and sediment load in the Pearl River estuary from the 1950s to 2020, finding that annual sediment load and suspended sediment concentrations declined drastically despite variable water discharge. The changes were driven by climate variability and intensifying human activities such as dam construction and sand mining.
Soil erosion and sediment dynamics in the Anthropocene: a review of human impacts during a period of rapid global environmental change
This review examines how human activities have altered soil erosion and sediment transport patterns, particularly since the mid-twentieth century. Researchers found that land use changes, deforestation, and agriculture have dramatically increased erosion rates, while dams and reservoirs have disrupted natural sediment flow to oceans. The study highlights how these changes affect global climate, water security, and the transport of pollutants including microplastics through river systems.

What Determines the Future Ecological Risks of Wastewater Discharges in River Networks: Load, Location or Climate Change?
Researchers developed a systematic framework for assessing future ecological risks from wastewater treatment plant (WWTP) effluents in river networks by combining plant size class as a proxy for pollutant load with stream order as a proxy for discharge location, applying it under climate change scenarios to show that streamflow reduction in receiving rivers will significantly worsen ecological risk even without increases in pollutant loads.
Anthropogenic changes in waterways produce “drought-like” layers in shelf sediments
Damming and waterway diversions have reduced sediment delivery to continental shelves in patterns that mimic drought signals in the sedimentary record, potentially confounding paleoclimate reconstructions that rely on shelf sediment composition to infer past precipitation and river flow.
Climatic and anthropogenic regulation of carbon transport and transformation in a karst river-reservoir system
Researchers analyzed dissolved inorganic carbon along a cascade of seven dam reservoirs in a karst river system in southwest China over one hydrological year, finding that cascading dams collectively exert a stronger effect on carbon cycling than single dams, with water temperature and hydraulic retention time jointly controlling how much carbon is retained or transformed.
The Effects of Climate Variation and Anthropogenic Activity on Karst Spring Discharge Based on the Wavelet Coherence Analysis and the Multivariate Statistical
Researchers analyzed climate variation and human activity effects on karst spring discharge using wavelet coherence analysis, finding that anthropogenic factors including land-use changes increasingly influence groundwater dynamics alongside natural climate variability.
Suspended sediment dynamics and the related environmental risk assessment in a sensitive water area
Researchers used 2D hydrodynamic modeling to show that suspended sediment loads in China's Nanji Mountain Nature Reserve vary strongly with seasonal river input from the Ganjiang, and that wet-season sediment pulses carry microplastic and nutrient fluxes up to ten times higher than dry season — elevating ecological risk precisely when waterbird populations are lower.
Interactions of natural and anthropogenic drivers and hydrological processes on local and regional scales: A review of main results of Slovak hydrology from 2019 to 2022
This review synthesizes major results from Slovak hydrological research from 2019 to 2022, examining how natural and anthropogenic drivers interact with hydrological processes at local and regional scales in a country with high spatiotemporal variability in runoff regimes. The authors highlight findings related to extreme floods and droughts, climate change impacts, and advances in monitoring, modelling, and water resources management relevant to Central European hydrology.
Human-environment interactions in the Anthropocene – a case study on reservoir sediments in Central Europe
Researchers analyzed sediment cores from Central European reservoirs to reconstruct a century of changing sediment fluxes, heavy metal contamination, and microplastic inputs linked to human land use change and climate-driven erosion. Microplastics appeared in cores beginning in the mid-20th century, with accelerating accumulation rates tracking regional industrialization and plastic production growth.
Interconnected impacts of water resource management and climate change on microplastic pollution and riverine biocoenosis: A review by freshwater ecologists
Researchers reviewed how river hydrology, water resource management, and climate change interact to influence microplastic pollution in freshwater ecosystems. They found that floods can flush microplastics from catchments, while reservoirs act as both sinks and sources, and extreme weather events driven by climate change tend to concentrate microplastics and threaten aquatic organisms. The study highlights a critical gap in research that jointly addresses these interconnected factors and calls for integrated policy approaches.
Impact of watershed habitat quality based on land use: a case study of taking Ciyao River Basin
Land use change analysis in the Ciyao River Basin from 1985 to 2020 showed that habitat quality declined in areas with increased agricultural and urban expansion, highlighting land use as a key driver of watershed ecological health. The findings support land use planning as a tool for biodiversity and water resource protection.

Analysis of hydrochemical characteristics and genesis of water-deficient rivers in China: a case study of the Ciyao River Basin in Shanxi Province
This study analyzed the chemical characteristics and origins of water in the Ciyao River Basin, a water-scarce region in China's Shanxi Province. Researchers collected water samples across wet, normal, and dry seasons and found that the water chemistry was influenced by both natural rock weathering and human activities. The findings provide baseline data for managing water quality in regions where water scarcity makes understanding pollution sources especially critical.

Unraveling the impacts of meteorological and anthropogenic changes on sediment fluxes along an estuary-sea continuum
Researchers ran a 22-year computer simulation of France's Seine Estuary to separate the effects of weather patterns from human engineering changes — like dredging and narrowing the channel — on how sediment flows between the estuary and the sea. They found that human modifications have fundamentally shifted the estuary from a sediment-exporting to a sediment-trapping system, with important implications for how pollutants like microplastics accumulate in estuarine environments.

Causes, Responses, and Implications of Anthropogenic versus Natural Flow Intermittence in River Networks
Researchers reviewed the differences between natural and human-caused flow intermittence in rivers, examining how anthropogenic drivers such as dams and water diversions alter drying patterns compared to natural seasonal cycles. They found that human-caused flow intermittence produces distinct ecological impacts because the affected organisms have not evolved adaptations to these artificial drying regimes. The study emphasizes that failing to distinguish between natural and anthropogenic intermittence could undermine river management and increase risks to downstream ecosystems.
