Example Water Content Profiles.
Water content profiles through time for a clay soil examined in response to: (a.) drainage, (b.) infiltration, and (c.) infiltration followed by drainage. Horizontal dashed lines show the surface layer depth. (d.) for a-c. Horizontal dashed lines show the time-averaged change in Lw.

Soil Classifications Plotted on the USDA Texture Triangle.
Soil classifications plotted based on (a.) USDA soil classification, (b.) hydraulic conductivity (Ks) and for: (c.) infiltration, (d.) drainage, (e.) infiltration followed by drainage, and (f.) summation of
from only infiltration and only drainage. The USDA triangle is shaded by soils texture, the remaining panels are shaded by
over the simulated period in the uppermost 30 cm.

Predictive Effectiveness for each Classification.
Time averaged values within each cluster. The symbol shows the mean value and the bars represent minimum and maximum values within the cluster. Classifications are labeled as in Fig 3

Soil Map Prediction Variation.
Soil maps showing the range of following infiltration and drainage based on the classification of (a.) USDA soil texture and (b.) infiltration and drainage. Soil maps showing two standard deviations of the values of change in length of water following infiltration and drainage based on the classification of (c.) USDA soil texture and (d.) infiltration and drainage.
