Leveraging the TabPFN Algorithm for High‐Resolution Mapping of Groundwater Bicarbonate and Its Scaling Risk Across China

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Large‐scale groundwater quality prediction is often constrained by sparse sampling, limiting the reliability of spatial assessments. This study introduces Tabular Prior‐data Fitted Network (TabPFN), a machine learning model based on prior‐fitting networks, to address this challenge and enable high‐precision mapping of groundwater bicarbonate ...

Chemical stimulation of geothermal reservoirs using retarded acid systems: current developments and potential directions

open access: yesGeothermal Energy
Stimulation techniques to enhance fluid pathways are an important tool to make geothermal projects economically feasible. So far, hydraulic stimulation is used almost exclusively for reservoir-wide improvement of the permeability, but induced seismicity ...

Spatiotemporal Patterns of Nutrient Fluxes in an Agricultural Reservoir

open access: yesJAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Reservoirs are vital tools for managing riverine water resources but also influence water quality through in‐lake nutrient (i.e., nitrogen [N] and phosphorus [P]) dynamics that affect downstream ecosystems. This study presents a multiscale spatiotemporal characterization of water quality in Carlyle Lake, an agriculturally impacted reservoir in

Hydrochemical Characteristics of High‐Temperature Geothermal Fluids and Quantitative Assessment of Wellbore Scaling in the Yangbajain Geothermal Field, Tibet

open access: yesGeofluids, Volume 2026, Issue 1, 2026.
Severe calcium carbonate scaling occurs in the wellbores of high‐temperature geothermal wells in the Yangbajain Geothermal Field. Based on sampling and laboratory analysis of the geothermal field, this study investigates the hydrogeochemical characteristics of the geothermal fluids, estimates the reservoir temperature, and reconstructs the bottom‐hole ...

Mechanism of Deep Brine Potash Enrichment in the Damenkou Area, Qaidam Basin, by Tectonic‐Sedimentary Coupling

open access: yesGeofluids, Volume 2026, Issue 1, 2026.
In recent years, the Damenkou Area in the Qaidam Basin has been identified as an important area for deep‐brine potash resource exploration. Previous studies on the origin of the deep basin brine have mostly focused on known mining areas. However, there is still a lack of understanding of how tectonics and sedimentation jointly control K+ enrichment in ...

Seasonal Changes and Hydrogeochemical Factors Influencing Groundwater Quality in Nannilam, Thiruvarur District of Tamil Nadu, India

open access: yesGeofluids, Volume 2026, Issue 1, 2026.
The purity of groundwater in Nannilam Taluk, which is situated in the Cauvery delta region of Tamil Nadu, India, is the primary focus of this investigation. In order to evaluate the physicochemical properties and efficacy of the groundwater for irrigation purposes, a total of 100 samples were collected from open wells, bore wells, and hand pumps during

Lake–Groundwater Biogeochemical Interactions in a River‐Delimited System: The Groundwater and Lakes Urban Observatory (GLUO)

open access: yesInternational Review of Hydrobiology, Volume 110, Issue 2, Page 135-150, December 2025.
ABSTRACT Preservation of urban aquatic ecosystems is of primary importance for human well‐being, biodiversity protection and the future of society. Lake–groundwater–river interactions within urban floodplains harbour intrinsic fragility, yet remain largely understudied.
