This card allows the user to define solid-aqueous phase partition coefficients and porous media dependent hydraulic dispersivities. This card is required only for simulations involving transport of solutes. This card differs from the Solute/Fluid Interaction Card because the input parameters declared are dependent on both the solute and rock/soil type. For every solute defined on the Solute/Fluid Interaction Card, every rock/soil type defined on the Rock/Soil Zonation Card must be referenced. With the IJK Indexing option, node dependent parameters are entered via external files, and node independent parameters are entered directly on the card.
