Figure

Table 1. Hydrodynamic parameters of soils: , ,  are the saturated water content, the residual water content and the hydraulic conductivity, respectively,  α and n are the Van Genuchten parameters [32] and   is the bulk density.
Figure 2b shows a good correlation between the simulated concentration and those observed for both homogeneous and layered medium and proves the validity of the analytical model used to predict the  dis-persivity.
