Fluvial sediment fluxes are reshaping coastal water colour, geomorphology, and ecological processes, yet schemes based on single-river loads or shoreline change may miss land-sea responses. We combine SSC records from 19 river stations across nine Chinese basins (2004-2024) with MODIS reflectance to characterize clearing, brightening, regional...

Changes in land use over space and time are key drivers of water pollution. However, current studies on landuse–water-quality relationships in small watersheds are insufficient to support regional development. Comparative research across large-scale watersheds can better inform water environmental protection, yet such studies remain limited. This...

Coastal wetlands serve as vital ecological buffer zones between marine and terrestrial systems, performing crucial roles in the protection of coastal erosion, wave and tsunami protection, and maintaining ecological functions. However, these important wetlands are increasingly being destroyed and incessantly threatened by human activities. The...

Study Region: The Ebinur Lake Watershed, located in Northwest China, serves as a crucial ecological barrier for the region. Study Focus: Over the past two decades, Ebinur Lake and its surrounding marshes have experienced a significant loss of water area due to excessive human exploitation and encroachment, resulting in severe ecological degradation...

Although water is a vital finite resource for sustaining life, it is under constant pressure from anthropogenic activities. Among the different types of surface water, lakes are particularly difficult to restore once water quality deteriorates due to their hydrological cycles and complex dynamics. This study compares policy implementation and its...

Rivers play a crucial role in nutrient cycling, yet are increasingly affected by eutrophication due to anthropogenic activities. This study focuses on the Barato River in Hokkaido, Japan, employing an integrated approach of field measurements and Sentinel-2 satellite remote sensing to monitor eutrophication as the river experiencing huge sewage...

Water cycle resilience represents a vital part of sustainable water resources management for a region with severe water vulnerability issues. However, despite their importance, a current lack of systematic monitoring mechanisms has contributed to an insufficient grasp of their distribution in relation to water resources management practices, as...

Japan is considered a water-rich country. Yet, recent socioecological history suggests that the country has undergone some drastic changes in its water environment as an extended effect of its post-war industrialization and urbanization. On the other hand, Japan also houses ingenious and time-tested methods of water management in its traditional...

Dynamic monitoring of reservoir water storage in arid areas is important for water resources assessment, hydroelectric power generation and agricultural irrigation. However, existing reservoir water calculation methods often rely on in-situ measurements, which limits their application in data scarce regionals and for regional scale analyses. Hence...

Central Asia's semi-arid regions, vital for sustaining vast populations and diverse ecosystems, are under heightened environmental stress. Among these regions, the Tuul River Basin, home to over half of Mongolia's population, characterizes the challenges posed by contemporary environmental shifts. This basin, a hub in Mongolia's socio-economic...
