Fig. 3. Non-aged 111Cd breakthrough data for (a) the E horizon, (b) the Bh horizon, (c) the Bh/C horizon with high flux, and (d) the Bh/C horizon with low flux. Curves represent predictions of 111Cd concentrations using the convection–dispersion (CDE) model with independently determined parameters (predicted local equilibrium [LEA]), using the optimized two-site model (TSM) with k and n determined from batch experiments (fitted two-site model [TSM], batch k and n), and using the optimized TSM model with k and n also fitted (fitted TSM, optimized k and n).
