The amount of rainfall (mm) recorded for the most recent rain event at the site prior to litter sample collection. For litter samples collected to serve as the minimum and maximum saturation points of the curve, these values were manually set. Sample bout 99 was saturated in the lab; the rainfall total for that bout reflects the average amount of water, in mm poured on each litter sample. Litter samples collected after long drying events had no recent rainfall; these were artificially set to 0.001 mm rainfall to represent the dry start of the wetting curve.
