The interplay between mixing and reactive processes plays a pivotal role in a range of
biogeochemical processes controlling the transport, transformation and turnover of chemical …

Mixing-driven reactions in porous media are ubiquitous and span natural and engineered
environments, yet predicting where and how quickly reactions occur is immensely …

Mixing fronts, where fluids of different chemical compositions mix with each other, are known
to represent hotspots of chemical reaction in hydrological systems. These fronts are typically …

Simulations of detailed geochemical systems have traditionally been restricted to Eulerian
reactive transport algorithms. This note introduces a Lagrangian method for modeling …

The purely Lagrangian algorithm for chemical reactions introduced by Benson and
Meerschaert (2008) suffers from a low‐concentration resolution problem. We alleviate the …

The unsaturated zone, located between the soil surface and the phreatic level, plays an
important role in defining the fate of any substance entering the subsoil. In addition to the …

The phenomenon of incomplete mixing reduces bulk effective reaction rates in reactive
transport. Many existing models do not account for these effects, resulting in the …

Abstract The Spatial Markov Model (SMM) is an upscaled model that has been used
successfully to predict effective mean transport across a broad range of hydrologic settings …

Recent advances in random walk particle tracking have enabled direct simulation of mixing
and reactions by allowing the particles to interact with each other using a multipoint mass …

Topographic relief and river bedforms generate nested streamline patterns, which drive the
propagation and mixing at depth of changes in surface water concentration or temperature …
