Laboratory Experiments on the Effect of Microtopography on Soil-Water Movement: Spatial Variability in Wetting Front Movement

Table 2

Small soil box final cut wetting front depths.

Exp^1	Surface location
	Large depression	Small depression	Smooth area^2
S1 WF (cm)	3.00	3.00	4.50
S2 WF (cm)	5.00	4.75	5.75
S3 WF (cm)	8.50	9.00	9.75
S4 WF (cm)	13.00	13.50	14.75

¹ S1–S4 refer to Exp. S1–S4, respectively; WF is the final cut wetting front depth relative to the surface.
²Smooth area wetting front depths are the average of smooth areas no. 1 and no. 2 (Figure 1).
