Air Flow Dynamics in Wet Soils: Challenges and Knowledge Gaps

by Ilan Ben-Noah 6 July 20235 July 2023

Modeling air flow in wet porous media relies on quantifying the combined role of fluid and media properties and flow dynamics on the microscale displacement mechanisms and macroscale unstable flow.

GPS Observations Sense Groundwater Change in Australia

by Annette Eicker 20 April 202319 April 2023

By exploiting the fact that changes in groundwater cause deformations of the Earth’s surface, GPS receivers are used to detect groundwater changes related to extreme events and to seasonal oscillations.

Reaching New Levels in Groundwater Monitoring

by Caroline Hasler 3 November 20223 November 2022

As regions around the world face record-breaking droughts, researchers are using seismology to track groundwater levels and show that sustainable policies reduce strain on aquifers.

Modeling Groundwater Responses to Earth Tides

by Beatriz Quintal 19 October 202217 October 2022

Tidal fluctuations in water well levels can reveal characteristics of the subsurface, and a new model based on coupled physics delineates the limitations of inherently simplistic analytical solutions.

Groundwater May Fix as Much Carbon as Some Ocean Surface Waters

by Carolyn Wilke 28 July 20227 September 2022

Microbes from wells as deep as 90 meters created organic carbon at a rate that overlaps with some nutrient-poor spots in the ocean.
