Fig. 4. Comparison of the means (thick curves) and variations (range of two standard deviations, thin curves) of (a) capillary tension (Pf = log, where is pressure head) and (b) soil moisture content () predicted by the stochastic model, with parameters semivariogram = 5 cm and correlogram = 2, to measured values at the Jyndevad site. The crosses represent the mean, and the vertical bars indicate the range of variations of the local measurements (from Jensen and Mantoglou, 1992; reproduced by permission of the American Geophysical Union).
