FIG. 6. Representative apparent soil moisture–inverted resistivity sections collected during Wetting Cycle 1 in the Vertisol: (a) 1 May; (b) 24 May; (c) 29 May; (d) 15 June; (e) 22 June; (f) 20 July; and (g) 16 Aug. 2005. The lateral extent of the microhighs (MH), microlows (ML), and the intermediate microrelief (MI) are shown in Fig. 6a. The areas marked "P" in (c) denote preferentially saturated portions of the soil in the section. The absolute error values refer to the errors in % from the robust inversion of the apparent resistivity data.
