Water Release Curve

MAXDRYDE = maximum dry density (g/cc)
OPTMOIST = optimal moisture

There are up to three replicate water release curves possible - but the number in any profile can vary from 0 to 3. The first curve is represented by first 13 parameters listed below. Note that actual suctions in this group are not identical to those in the subsequent two replicates. Water contents are in percents (range of 0 to 100).

The terminal two replicates have identical suctions and MAY have replicated values at 15 bar, i.e., there may be up to four such values in the two replicates and possibly 5 such values in any given profile. Any value from 0 to 5, however, is possible. We advise caution when using these data for hydraulic modeling since only a few erroneous or missing values can radically affect curve fittings. You should verify the plausibility of each release curve before utilization.
