  		Fig. 1. Example of a simulated drainage curve for a b = 3, j = 5, D = 1.771... randomized Sierpinski carpet (realization #1), where S is the relative saturation and logb(h/hmin) is log to base b of the scaled suction. Also shown are the predicted curve based on Eq. [1] and the best fit curve from Eq. [16] with Pd = 0.786 (error sums of squares, ESS = 0.005).

  		Fig. 3. Example of an experimentally determined drainage curve for soil (Palouse silt loam), where S is the relative saturation and h is the suction. Also shown are the best fit curves for Eq. [1] and [17]. Parameter estimates for these curves are given in Tables 4 and 5, respectively.
