Figure 2.10. 2-2 Horizontal-Vertical Model results displayed at the (a) surface and at (b)
400 ft depth. Note that the layers look nearly identical and there is a vertical tubing effect,
especially noticeable along the southern boundary (indicated by arrows). Also, the area of
hydrofacies 1 (dark blue) deposits in the east is much smaller than the raw data show (Fig.
2.9) The scale indicates values of hydraulic conductivity in ft/day.
