A simple method for estimating the spatial variability of the soil-water flux from known variability of soil microhydrologic properties is presented. The method is based on the theory of approximating a differentiable function using Taylor-series expansion (TS-method). Published data for means and variances of the soil microhydrologic properties were used to estimate the mean and variance of the soil-water flux in a draining profile of Panoche soil. These values were compared with those estimated using a Monte Carlo simulation procedure (MC-method) on the same set of data. Relative advantages and disadvantages of these two methods are briefly discussed.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
