Hydrochemistry types of the Bauru Aquifer System in the State of São Paulo

Revista Águas Subterrâneas, 2016
Groundwater is used for public supply in 55% of Brazilian municipalities. In the state of São Paulo approximately 72% of the cities, with an estimated population of 5.5 million inhabitants, are fully or partially supplied by groundwater, being Bauru ...

Quantifying Deep Groundwater Contributions to Streamflow With Inequality‐Constrained EEMMA From Sparse Isotope Series in Alpine Permafrost Basins

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract In alpine permafrost basins, dry‐season runoff largely depends on subpermafrost groundwater (BPG, deep groundwater), yet cryohydrogeological conditions are complicated by time‐varying hydrothermal regimes. Combined with the storage and regulation effects of permafrost on runoff, hydrograph‐based estimates of the fractional contribution of BPG ...

Uncovering the Underestimated Greenhouse Gas Emissions of Hydropower Reservoirs: A Global Synthesis

Global Biogeochemical Cycles, Volume 40, Issue 9, September 2026.
Abstract Hydropower reservoirs, long considered as a clean energy solution, are increasingly recognized as major greenhouse gas (GHG) emissions hotspots. However, over 97% of these hydropower reservoirs remain unmonitored, creating major uncertainties in global GHG budgets.

Hydrogeochemical Dynamics and Response of Karst Catchment to Rainstorms in a Critical Zone Observatory (CZO), Southwest China

Frontiers in Water, 2020
Karst water is vital for local drinking and irrigation but is susceptible to contamination. Hydrochemistry, which is highly related to carbonate weathering in karst catchments, can affect water quality and respond rapidly to climate change.

How the Physical and Chemical Properties Affect the Heavy Metal Content in Surface Water in Different Types of Peatlands

Land Degradation &Development, Volume 37, Issue 13, Page 9254-9265, 15 August 2026.
ABSTRACT Only ~3% of the global land surface is covered by peatlands, yet more than one‐third of global soil carbon is stored in these ecosystems and contaminant filtration can be provided. The extent to which peat humification (Fibric–Hemic–Sapric) is linked to dissolved heavy metals in peatland surface waters has remained poorly quantified at a ...

Anaerobic Corrosion Phenomena of Cast Iron and Copper in Artificial Groundwater at Elevated Temperature

Materials and Corrosion, Volume 77, Issue 8, Page 1262-1277, August 2026.
This study examines corrosion of copper and cast iron as candidate canister materials for high‐level radioactive waste disposal in contact with bentonite suspension. The influence of three electrolyte compositions on corrosion behavior under repository‐relevant conditions is assessed.

Classification and Conceptualization of Karst Recharge Processes Through Spectral and Change Point Analysis of Drip Water Dynamics

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Karst aquifers are notoriously heterogeneous, making it challenging to characterize recharge dynamics using traditional, static indicators. Percolating (drip) water records, when analyzed at high temporal resolution, offer insights into flow mechanisms in karst vadose zones.

Conserving the World's Specialist Riverine Birds

WIREs Water, Volume 13, Issue 4, July/August 2026.
Specialist riverine birds constitute a diverse bird group globally, highly adapted to rivers and streams. They are at risk from multiple threats to rivers, riparian zones and river catchments including impoundment, hydropower and abstraction; land‐use changes including urbanization and agricultural intensification; traditional and emerging pollutants ...

Age and Land Use as Factors Differentiating Hydrochemistry and Plant Cover of Astatic Ponds in Post-Agricultural Landscape

Journal of Water and Land Development, 2014
Small, astatic ponds are important features of post-glacial landscape, which support heterogeneity and biodiversity of agricultural areas. In the presented research we explored differences in hydrochemistry and plant cover of 20 small ponds located in ...
