The Critical Role of the Intermittent Two‐Phase Flow Topology on the Solute Dispersion in Partially Saturated Porous Media

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Intermittent flow is a widely recognized phenomenon across various fields, characterized by the spatial‐temporal fluctuations of the two‐phase topology. However, its implications for solute dispersion and mixing remain insufficiently understood.

Modeling Interactions and Dynamic Saturation Processes in Karst Media

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract The simulation of karst aquifers is highly challenging due to complex conduit‐matrix interactions. This study utilizes KarstFOAM, a high‐fidelity, physics‐based numerical model, to address these challenges. KarstFOAM integrates (a) a unified single‐domain Forchheimer–Darcy–Brinkman–Stokes (FDBS) formulation that transitions naturally across ...

Effect of Submerged Vegetation on Water Surface Geometry and Air–Water Momentum Transfer

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Understanding how submerged vegetation modifies the water surface is crucial for modeling momentum exchange between shallow waters and the atmosphere. In particular, quantifying its impact on the equivalent aerodynamic roughness of the water surface is essential for improved boundary‐layer parameterization in oceanic and atmospheric models. In
