New Precipitation Is Scarce in Deep Soils: Findings From 47 Forest Plots Spanning Switzerland

open access: yesGeophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract As precipitation infiltrates into soils, it can recharge them, displace previously stored waters, or bypass already‐filled pores. Using 3,697 δ2H and δ18O measurements of water collected nearly monthly over >3 years in 47 forest plots across Switzerland, we present a systematic investigation of the controls on mobile soil water transport.

Effects of preferential flow on snowmelt partitioning and groundwater recharge in frozen soils

open access: yes, 2019
. Snowmelt is a major source of groundwater recharge in cold regions. Throughout many landscapes snowmelt occurs when the ground is still frozen; thus frozen soil processes play an important role in snowmelt routing, and, by extension, the timing and ...

Focused aquifer regeneration produced outsized gains for a threatened fish in a populated, dryland watershed

open access: yesEcosphere, Volume 16, Issue 8, August 2025.
Abstract A combination of groundwater pumping and shifting precipitation patterns is drawing down aquifer levels in many of the world's drylands and is predicted to generate widespread loss of perennial streamflows over the next few decades. This process broadly threatens freshwater biota, especially in arid and semiarid regions.

Determination of Groundwater Vulnerability for Protection of the Drinking Water Basins: A Case Study From Türkiye, Kesikköprü Dam Lake Basin

open access: yesGlobal Challenges, Volume 9, Issue 8, August 2025.
Groundwater vulnerability is evaluated in a critical drinking water basin under the threats of climate change and population growth. Using GIS‐based DRASTIC modeling and field validation, high‐risk zones are identified. The results offer strategic insights for protecting Ankara's groundwater resources against escalating environmental and anthropogenic ...
