In the delved soil, the dye staining was consistent with the infiltration results shown in Table 4 in which greater depths of infiltration corresponded with greater infiltration rates along the delving lines.
In both regions of the delved soil (on the delving line and off-line) the occurrence of finger flow was greatly reduced and a larger area of soil profile was wetted, particularly on the delving-line region.
The wetting pattern of the undelved soil quite closely resembled that in the off-line region of the delved soil when the latter is transposed upward by ~0.
1 m of the B horizon, both regions of the delved soil were significantly wetter than in the undelved profile (Table 6).
05) were found between the two delved regions and the undelved soil.
Both the on- and off-line regions of the delved soil had significantly greater wetted areas than the undelved soil: 25% and 22%, respectively, in the A1 horizon; and both 18% in the A2e horizon (Table 8).
The reduction in hydraulic conductivity between the A and B horizons at this site was less abrupt than that at sites A and B (Table 4), so less water ponded above the A-B boundary in both the delved and undelved soils here.
