Fig. 2. The predicted effluent breakthrough curves (BTCs) are plotted along the observed BTCs for the three soil columns. The predicted BTCs are generated using the estimated parameters shown in Table 1. Analytical solutions of the mobileimmobile model from CXTFIT are used to calculate the effluent BTCs.
