Flow and Transport Through Unsaturated Fractured-Porous Rocks

Chapter
Part of the Theory and Applications of Transport in Porous Media book series (TATP, volume 25)

Abstract

The models discussed in the previous chapter can potentially be expanded to study hydrological processes in the unsaturated zone presented by fractured formations. The dual porosity models are of primary interest for describing infiltration and solute transport. In these models the matrix acts as a source or sinks for water imbibition and dissolved component diffusion between the adjacent fractures, and it is more often assumed that solutes cannot move globally through matrix by advection. However analysis of flow and transport in partially saturated media may require incorporating a dual porosity–dual permeability modeling concept. In the dual permeability matrix diffusion models, the solute can transport globally through matrix by advection as well as diffusion (Gerke and van Genuchten 1993a; Ho 2001a, b; Mathias et al. 2005; Gerke 2006a, b; Houseworth 2006).
