In addition to the linear retardation mechanisms associated with infill and coating materials, Pipes can also represent interchanges with immobile storage zones along the length of the pathway. These exchange processes act orthogonal to the flow direction. The approach of representing such storage zones was originally developed for modeling fracture flow with matrix diffusion, but has also been used to model flow through porous media.
Pipes can represent two types of storage zones:
•matrix diffusion zones; and
•a “stagnant” dispersive zone.
