Fig. 7. The behavior of optimized hydraulic parameters for GRIZZLY as a function of the user index for the van Genuchten equation with k
representing the Brooks-Corey equation: (a) values for
s, hvG or hBC and mn0,k or
0 divided by their maximum obtained for either
r = 0 or
r > 0 as a function of k (error bars denote 95% confidence limits) and (b) adjusted RMSE as a function of k with
r fixed (=0) or optimized (
0).
