Groundwater Temperature Processes and Patterns: Implications for Stream Thermal Regimes

WIREs Water, Volume 13, Issue 2, March/April 2026.
Shallow groundwater temperatures are controlled by ground surface temperatures and are influenced by climate change and land cover changes. Deeper groundwater temperature is constant year‐round, making it cooler (warmer) in the summer (winter) than surface water, and exhibits a lagged response to surface warming.

A Combined Method of Seismic Monitoring and Transient Electromagnetic Detection for the Evaluation of Hydraulic Fracturing Effect in Coal Burst Prevention

Sensors
In order to mitigate the risk of roof-dominated coal burst in underground coal mining, horizontal long borehole staged hydraulic fracturing technology has been prevailingly employed to facilitate the weakening treatment of the hard roof in advance.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Integration of airborne transient electromagnetic models with ground geophysics and borehole data for groundwater mapping in Hawkes Bay region, New Zealand

, 2023
As part of the Hawke's Bay 3D Aquifer Mapping Project (3DAMP), airborne electromagnetic data have been collected over several basins. The project was a three-year initiative (2019 - 2022) jointly funded by the Provincial Growth Fund (Knoa Regional Economic Development & Investment Unit), Hawke's Bay Regional Council (HBRC) and GNS Science (GNS).

Broadband Dielectric Analysis of Clays: Impact of Cation Exchange Capacity, Water Content, and Porosity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Clay‐rich soils and sediments are key components of near‐surface systems, influencing water retention, ion exchange, and structural stability. Their complex dielectric response under moist conditions arises from surface–ion electrostatics and diffuse double layers that govern transport and retention processes. This study explores the broadband
