“…Over the last decades, reactive transport modeling has become an essential tool for the study of subsurface processes involving flow, transport and geochemical reactions (Deng et al., 2022; Steefel et al., 2005). This discipline arises from the junction of two scientific communities, namely geochemistry, and transport in porous media.…”

Micro‐continuum models are versatile and powerful approaches for simulating coupled processes in two‐scale porous systems. Initially oriented for modeling static single‐phase flow in microtomography images with sub‐voxel porosity, the concept has been extended over the years to multi‐phase flow, reactive transport, and poromechanics. This paper introduces an integrated micro‐continuum framework to model coupled processes in porous media. It reviews state‐of‐the‐art models and discusses applications in geosciences including Digital Rock Physics with sub‐voxel porosity, moving fluid‐solid interface at the pore‐scale due to geochemical reactions, fracture‐matrix interactions, and solid deformation. Finally, the paper discusses future developments in micro‐continuum models.

“…In pore-scale models described in Figure 14a, each point in the pore space is occupied by either a fluid or solid phase [150], and the fluid-mineral interface moves with the surface reaction of mineral precipitation [172]. So far, pore-scale models have proven to be a mature tool for studying flow patterns, and the evolution of hydraulic properties during biogeochemical processes in the pores has also been simulated.…”

The mixing of terrestrial groundwater and seawater creates dynamic reaction zones in intertidal areas, where land-derived Fe(II) is oxidized to Fe(III) and then precipitates as Fe hydroxides at the groundwater–seawater interface. These hydrogeochemical processes contribute to the formation of iron bands at the saltwater wedge (SW) and beneath the upper saline plume (USP). This study provides a comprehensive review of physical and geochemical processes at field scale in coastal areas, explores the impact of mineral precipitation on pore structure at pore scale, and synthesizes reactive transport modeling (RTM) approaches for illustrating continuum-scale soil physio-chemical parameters during the evolution of porous media. Upon this review, knowledge gaps and research needs are identified. Additionally, challenges and opportunities are presented. Therefore, we reach the conclusion that the incorporation of observational data into a comprehensive physico-mathematical model becomes imperative for capturing the pore-scale processes in porous media and their influence on groundwater flow and solute transport at large scales. Additionally, a synergistic approach, integrating pore-scale modeling and non-invasive imaging, is equally essential for providing detailed insights into intricate fluid–pore–solid interactions for future studies, as well as facilitating the development of regional engineering-scale models and physio-chemical coupled models with diverse applications in marine science and engineering.

“…While the topic has received considerable attention in the last decade (see Deng et al (2022) for a recent review on reactive transport models of geochemical dynamics in porous media), modeling the complex matrix-biomass-aqueous complexes interactions and their spatio-temporal effects on the porous microstructure remains extremely challenging due to three major issues:…”
