Abstract:

contents of the model
simulation of reactive solute transport of contaminants in the presence of reactive mobile carriers like DOC. It was specifically developed for understanding the processes leading to DOC mediated (facilitated and reduced) transport of hydrophobic organic contaminants.
principles of the model
advection-dispersion equation, isotherms (nonlinear), finite element numerics, nonequilibrium processes, two component flow through media.
