Observed 50-mm depth (filled circles) and 500-mm depth (open circles). Richards' equation (with time constants from Table 1) 50-mm depth (solid line) and 500-mm depth (dashed line)

View larger version (18K): [in a new window]   Fig. 6 Cumulative drainage from six undisturbed soil cores under dry antecedent conditions reported by Smettem et al. (1994). The time constant model is shown for three of the cores. Observed drainage: Core 1 (open circles), Core 3 (open triangles), and Core 4 (filled triangles). Time constant model: Core 1 (dashed line), Core 3 (dotted line), and Core 4 (dashed and dotted line)
