Effects of Dissolution Regimes on Flow Channelization and Solute Transport in 3D Fracture Networks: Insights From Graph‐Based Reactive Transport Modeling

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract We investigate how mineral dissolution reshapes flow pathways and solute transport in three‐dimensional discrete fracture networks using a computationally efficient graph‐based reactive transport model. The DFNs are inspired by field‐site observations of fractured carbonate and represent realistic connectivity and structural heterogeneity ...

On Utilizing Spatial Gradients to Discover Functional Relationships in Hydrology

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract The search for functional relationships is at the heart of any science, but has proven notoriously difficult in hydrology. Here, we define functional relationships as relationships between two or more variables that characterize the functions of hydrological systems.

A statistical approach for describing coastal karst aquifer: the case of the Salento aquifer (Southern Italy)

open access: yesAcque Sotterranee
A time series approach was proposed to improve the knowledge of a wide coastal karst aquifer. The approach combines time series decomposition, trend, autocorrelation and cross-correlation analyses using both daily and monthly temperature, rainfall and ...

Hydraulic Conductivity Behaviors of Karst Aquifer With Conduit-Fissure Geomaterials

open access: yesFrontiers in Earth Science, 2020
This study used laboratory analog and numerical experiments to simulate groundwater flow in karst aquifer and investigated the effect of dimension factors and water pressure on the hydraulic conductivity for karst groundwater flow in conduit-fissure ...

Regionalization of Optimal Baseflow Separation Using Catchment‐Scale Characteristics

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Empirical baseflow filters are widely used for baseflow separation. These filters rely on ad‐hoc parameters that introduce significant uncertainties in the calculation. A recent study by Mei et al. (2024, https://doi.org/10.1029/2023wr036386) optimized these parameters using environmental tracer data for 1,100 catchments across the Contiguous ...

Density–Inertia Coupling Drives Solute Trapping at Vertical Fracture Intersections

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Density‐driven flow and fluid inertia jointly shape solute transport in fracture networks, with implications for hydrogeology and subsurface engineering. While their individual effects are well recognized, their coupled impact remains underexplored.

Mechanisms of near‐normal sea water dolomitisation: Mesohaline‐reflux or syn‐depositional?

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
This study investigates the dolomitisation of the Eocene Dammam Formation on the Arabian Plate using petrographic, mineralogical, geochemical and isotopic analyses. The findings reveal two distinct dolomite types, formed primarily through normal‐to‐mesohaline sea water dolomitisation, challenging previous models such as sabkha‐meteoric mixing.

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.

Multi‐scale geophysical mapping of the brine and bedrock surfaces along the Dolores River, Paradox Valley, Colorado, December 2023

open access: yesNear Surface Geophysics, Volume 24, Issue 1, Page 36-49, February 2026.
Abstract Total dissolved solids derived from salt dome–sourced brine in the underlying alluvial aquifer substantially increase with distance in the reach of the Dolores River that passes through Paradox Valley in southwestern Colorado. The area has been the site of salinity control operations since the 1990s to reduce salt loading to the downstream ...

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
