Fig. 12.38 Profiles of means (a, b) and standard deviations (c, d) of the bromacil concentrations
at four different time points. Solid curves denote simulated profiles obtained from the advection-
dispersion equation (a, c) and the mobile-immobile model (b, d). The different symbols denote
measured profiles at different times. Reprinted from Russo et al. (
