Analysis of Dual‐Porosity Model With Fissure Skin Effect in Confined Karst Aquifer

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract In fractured media with rough fissure skins, ignoring the fissure skin effect limits the accuracy of parameter inversion. In karst aquifers, groundwater storage and movement are typically governed by dual‐porosity models, where the fissure skin plays a key role in water exchange between fissures and the rock matrix.

Detecting Anomalies in Karst Aquifer Recharge: A Temporal Convolutional AutoEncoder Framework With High‐Frequency Temperature‐Conductivity Signals

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract The internal recharge dynamics of karst aquifers are difficult to resolve with traditional outlet‐based indicators, owing to their heterogeneous structure and nonlinear response. To address this, we propose a non‐invasive anomaly detection framework based on a Temporal Convolutional AutoEncoder (TCAE), which integrates high‐frequency ...

Offshore Groundwater Salinization and Flushing in the Canterbury Bight During Glacial‐Interglacial Cycles

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Offshore freshened groundwater (OFG) is a significant yet underexplored component of global water resources, occurring widely along many continental margins. However, its dynamics remain poorly constrained due to limited offshore observations and the absence of robust evaluation models for unambiguous emplacement interpretation.

Direct Flux Measurements Reveal CO2 Sinks in Icelandic Glacial Streams Driven by Weathering and Hydrological Mixing

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Glacier‐fed rivers are increasingly recognized as important components of high‐latitude carbon cycling, yet direct observations of CO2 exchange in proglacial streams remain limited, especially in young basaltic catchments. Here, we quantify spatial and seasonal patterns of CO2 exchange along a 3‐km reach of the glacier‐fed stream Virkisá ...
