Seeing China's Invisible Groundwater: Advances and Challenges

open access: yesWater Resources Research, Volume 61, Issue 6, June 2025.
Abstract In 2021, China adopted comprehensive “Groundwater Management Regulations” to address critical groundwater issues, building upon the foundation of a national groundwater monitoring network established by 2020. This commentary reviews the development of China's National Groundwater Monitoring Network, examines its current monitoring capacity ...

Incorporating Deep Learning Into Hydrogeological Modeling: Advancements, Challenges, and Future Directions

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 2, June 2025.
Abstract Hydrogeological modeling is essential for managing groundwater systems, especially in the transport and remediation of contaminants. Traditional modeling methods face challenges due to the increasing complexity and volume of data. Deep learning (DL) has emerged as a promising tool, offering significant improvements in accuracy and efficiency ...

Groundwater Flooding of Superficial Gravels in an Urbanized Catchment

open access: yesJournal of Flood Risk Management, Volume 18, Issue 2, June 2025.
ABSTRACT Groundwater behavior in superficial gravel aquifers is globally poorly understood, especially across urban regions where drinking water is sourced from elsewhere. This study focuses on one such region around Staines, SE UK, where local River Terrace Gravels form a thin (< 10 m) superficial aquifer.

Storage Dynamics and Groundwater–Surface Water Interactions in a Drought Sensitive Lowland Catchment: Process‐Based Modelling as a Learning Tool

open access: yesHydrological Processes, Volume 39, Issue 5, May 2025.
The past two decades have been dominated by negative anomalies in annual rainfall, causing a general lowering of water tables and persistent storage deficits. Spatio‐temporal patterns of recharge are also strongly influenced by vegetation cover, with coniferous forests having high evapotranspiration losses that inhibit groundwater recharge. Most stream
