FIG. 10. A synthetic evaluation of the five-layered model analysis using only ground penetrating radar (GPR) data for (a) Day 8 and (b) Days 1 to 8. For illustration purposes, only the 500 realizations with the lowest misfit values are included in the figure. The parameter ranges of the five realizations with the lowest misfit values are indicated with red and the "true" parameter value is shown with a red diamond; 
r is residual moisture content, 
and n are empirical parameters, Ks is saturated hydraulic conductivity.
