Fig. 4. Comparison of prediction of algorithm (described in text) with experimental water retention curve for the USDOE Hanford site soil, ITS 2-1418 (Freeman, 1995). 
t taken from lowest value achieved; 1 is calculated from Eq. [6] and shown with an arrow. Open squares consistent with Rieu and Sposito (1991) fractal scaling over entire range of moisture contents. Filled diamonds represent experimental values from Freeman (1995). Open circles are moisture contents predicted by algorithm described here.
