Impact of Groundwater Head Changes on the Permeability of Bedrock Aquifer‐Aquitard Systems

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Understanding how groundwater level changes affect the permeability of bedrock aquifer‐aquitard systems is important for groundwater management, yet this relationship remains poorly understood. This study focuses on Tangshan in the northeastern North China Plain, utilizing tidal response analysis to investigate the dynamic interplay between ...

Ubiquity and Causes of Soil Water Preferential Flow Across 17 Ecoregions

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Preferential flow (PF) in soil causes the rapid transport of water, nutrients, and contaminants into the subsurface, influencing groundwater recharge and streamflow. Data scarcity has hindered the quantification of PF occurrence and the identification of its drivers across diverse ecoregions.

Groundwater recharge in Brandenburg is declining – but why?

open access: yesNatural Hazards and Earth System Sciences
Abstract. Brandenburg is among the driest federal states in Germany, featuring low rates of groundwater recharge (GWR) across large parts of the state. This GWR is fundamental to both water supply and the support of natural ecosystems. There is strong observational evidence, however, that GWR has been declining since 1980: first, river discharge (which
