Abstract: The present paper focuses on the numerical model development of the colloid-facilitated contaminant transport using an equilibrium approach in the vadose zone of subsurface porous media. Flow in the vadose zone of subsurface ...

Abstract: In recent decades, extensive use of nitrogen fertilizers has drastically increased ammonium contamination in soil and groundwater. Ammonium contamination in soil is governed by the adsorption mechanism, which depends on ...

Abstract: We use an advection-dispersion-reaction equation, which accounts for both physical and chemical nonequilibrium, to study the effect of heterogeneity of the porous media on a spatial concentration profile. Distance-dependent ...

Abstract: Parameter estimation is a significant aspect of modeling flow through porous media. To avoid any nonuniqueness issues in parameters estimation, it is important to have a deep understanding of the information content and ...

Abstract: The transport of reactive solutes through fractured porous formations has been analyzed. The transport through the porous block is represented by a general multiprocess nonequilibrium equation (MPNE), which, for the fracture, ...

Abstract: In this paper, an advective dispersive virus transport equation, including first-order adsorption and an inactivation constant, is used for simulating the movement of viruses in fractured porous media. The implicit ...
