The present paper aims at investigating the applicability of the hybrid cells in the series model for pollution transport inside the layered porous media. For this purpose, four layers of the rock material were fallen inside the experimental flume, and eight sensors were longitudinally installed inside the media to obtain experimental BTCs. For the computation of the time parameters of the model, which is named by (λ,T_1 and T_2), two different methods of the (LSCF) and (MM) were examined. The sensitivity of the model and its temporal equations with different parameters have been assessed. Finally resulted that, at the fixed time step, the model is more sensitive to the λ parameter (advection zone time parameter) rather than residential time parameters. On the other hand, the moment relationships are more sensitive to the residential time parameters. A detailed computation of the related transport parameters was operated and the Peclet number, crossing velocity, dispersion coefficient, time to the max, and maximum concentration have been calculated. At the end of all, the applicability of the model for large-scale porous media has been proven with only one unit of the cells.
