Rock Physics of the Critical Zone: Models, Inversion, and Interpretation

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Rock physics models link geophysical measurements with subsurface petrophysical properties, such as porosity, mineral composition, and fluid saturation. While originally developed for hydrocarbon exploration, these models are increasingly applied in the near surface for quantitative interpretation of geophysical data.

Delivery and impact bypass in a karst aquifer with high phosphorus source and pathway potential

open access: yes, 2012
Conduit and other karstic flows to aquifers, connecting agricultural soils and farming activities, are considered to be the main hydrological mechanisms that transfer phosphorus from the land surface to the groundwater body of a karstified aquifer.

Non‐Perennial, Yet Predictable: Hierarchical Stream Activation Enables the Prediction of Channel Network Dynamics in Sporadically Monitored Catchments

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Predicting the dynamics of non‐perennial river networks is essential for hydrological modeling and water resource management. Yet, long‐term monitoring campaigns remains logistically challenging, particularly in remote and poorly accessible regions.

Review: The Yucatán Peninsula karst aquifer, Mexico

open access: yes, 2011
The Yucatán Peninsula karst aquifer is one of the most extensive and spectacular karst aquifer systems on the planet. This transboundary aquifer system extends over an area of approximately 165,000 km2 in México, Guatemala and Belize.

Reconstructing China's Natural Streamflow at 1‐km Resolution

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Climate change and intensifying human activities are placing unprecedented pressure on China's water resources, necessitating high‐resolution, naturalized streamflow records for effective management. We develop a 1‐km gridded fully coupled land‐surface‐hydrologic‐hydrodynamic modeling system for China based on the CLHMSv2.0 model.

Investigations of rapid groundwater flow and karst in the Chalk

open access: yes, 2009
This study, with fieldwork undertaken in the Pang and Lambourn catchments in Southern England, investigates the occurrence and distribution of rapid groundwater flow in the Chalk and evaluates the degree of karstification.

Enhanced Characterization of the Krania–Elassona Structure and Functioning Allogenic Karst Aquifer in Central Greece

open access: yesGeosciences, 2018
The present study highlights the importance of geological, hydrogeological, and hydrogeochemical characterization of a karst aquifer in building a conceptual model of the system.

The Role of Amplicon Length and Total DNA Length in Synthetic DNA Tracer Degradation and Adsorption During Transport Through Sand

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Synthetic DNA tracers are increasingly used in subsurface hydrological studies because their large sequence diversity enables the design of numerous uniquely identifiable tracers. However, previous studies have not isolated how amplicon length, flanking region length, and total DNA length independently control tracer degradation and adsorption

Supportive methods for assessing effective porosity and regulating karst aquifers

open access: yesActa Carsologica, 2010
Regulation of a karst aquifer implies engineering interventions designed to control its flow and manage its water reserves. One of the most important prerequisites for the feasibility and suc­cess of regulation projects is proper assessment of aquifer ef­
