Soil hydraulic properties as stochastic processes: II. Errors of estimates in a heterogeneous field.

Results of integral scales and coefficient of variations from Part I are applied to evaluate errors in estimating average values of several hydraulic properties. Based on the Ergodic Hypothesis and on standard statistical theory, an equation is derived to calculate the total field area and number of measurements needed to estimate (for a prescribed error) ensemble averages of a given hydraulic property. -from Authors
