Inconsistencies in GRACE‐Based Groundwater Storage Estimation—A Call for a Proper Use of Land Surface Models

open access: yesGeophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Estimating groundwater storage (GWS) anomalies by subtracting model‐derived components from Gravity Recovery and Climate Experiment (GRACE) terrestrial water storage (TWS) anomalies is a common practice in hydrology. Typically, land surface model (LSM) simulated soil moisture (SM), snow water equivalent, and canopy water content are removed ...

A High‐Precision Analytical Technique for Dissolved N2 Isotopes in Aquatic Systems: Biogeochemical Applications and Determination of Solubility Equilibrium Isotope Effects

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 19, 15 October 2025.
ABSTRACT Rationale The isotopic composition of dissolved dinitrogen gas (δ15N‐N2) in water can offer a powerful constraint on the sources and pathways of nitrogen cycling in aquatic systems. However, because of the large presence of atmosphere‐derived dissolved N2 in these systems, high‐precision (on the order of 0.001‰) measurements of N2 isotopes ...

PERHITUNGAN AWAL IMBUHAN AIRTANAH ALAMI DAERAH ALIRAN SUNGAI CIKAPUNDUNG-GANDOK (KAJIAN PERBANDINGAN)

open access: yesJurnal Sumber Daya Air
Groundwater recharge is a crucial factor in determining the permissible groundwater extraction within a watershed. In the Cikapundung watershed, the contribution of groundwater to raw water supply has been continuously declining, prompting a shift from ...

Delayed Effects of Water‐Limiting Conditions Influence the Ramet Demography of a Native Iterocarpic Thistle

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
Increasing temperatures and shifting precipitation patterns are major components of climate change. We used 20 years of demographic monitoring data (1990–2009) on native Cirsium undulatum (wavyleaf thistle) from two Sandhills prairie sites in the central Great Plains, USA, to assess long‐ and short‐term effects of weather variation on ramet dynamics ...

Assessing the potential of managed aquifer recharge using rooftop rainwater harvesting with shallow wells in peri-urban communities in Kumasi, Ghana

open access: yesDiscover Water
In many cities worldwide, groundwater levels have declined significantly due to climate change and increased water demand, necessitating artificial recharge.

Where do we expect to find deep plant roots?

open access: yesEcography, Volume 2025, Issue 10, October 2025.
Plant roots have been observed up to 70 m in depth – what would compel a plant to root so deeply? Earlier work shows that the climate, soil and drainage all affect rooting depth, but with conflicting results. For example, both the deepest and shallowest roots are found in arid regions.

Mathematical model of artificial groundwater recharge

open access: yesJournal of Environmental Engineering and Science
In this paper, four cities in India having different geographical structures, climates, and hydrological components were selected. An area of 500 m2 from each city has been studied. A mathematical model with three-dimensional components of hydraulic conductivity, hydraulic head in the aquifer, and other factors was adopted, in which additional ...
