Abstract

Contaminant transport with nonlinear sorption under nonequilibrium conditions is studied with the objective of finding exact formulae for solute concentrations. We introduce the concept of linear “caricature” isotherm and obtain the concentration profiles as travelling waves. The solution procedure does not make any simplifying assumptions such as the coupled effect of dispersion and nonequilibrium is negligible or local equilibrium is valid.
