FIG. 11. The misfit values of the five-layered model using only electrical resistivity tomography (ERT) data, using only ground penetrating radar (GPR) data, and combining ERT and GPR data in the analysis. For illustration purposes, only the 500 realizations with the lowest misfit are included in the figure. Only the misfit plot of the top three layers of the saturated hydraulic conductivity, K_s, and the empirical parameter n are shown.
