Solute/Porous Media Interactions Card Description (G)

A number of parameters are specified in the Solute/Porous Media Interaction Card.

Solid-Aqueous Partition Coefficient

Solid-Aqueous partition coefficient defines the interface equilibrium of a solute adsorbed on the solid and dissolved in the aqueous phase, and refers to the concentration of solute adsorbed on the solid phase (per unit mass of solid phase) over the concentration of solute dissolved in the aqueous phase (per unit mass aqueous phase). The longitudinal and transverse hydraulic dispersivities are properties only of the rock/soil type. 

Longitudinal Dispersivity

Longitudinal dispersivity is defined with respect to dispersion along the flow path and is assumed to be independent of the flow direction with respect to the porous media structure. 

Transverse Dispersivity

Transverse dispersivity is defined with respect to dispersion transverse to the flow path, independent of the flow direction.
