| ROSETTA Class Average Hydraulic Parameters |
|
The table below gives class-average values of the seven hydraulic parameters for the twelve USDA textural classes. Effectively, this table represents the first model of the hierarchical sequence. For the qr, q s, a, n and Ks parameters, the values have been generated by computing the average values for each textural class. For Ko and L the values were generated by inserting the class average values of qr, qs, a, n into Model C2 (see Rosetta's help file). This means that Ko and L are based on predicted parameters and may not be very reliable. The values in parentheses give the one standard deviation uncertainties of the class average values
