Values of erosion or deposition were interpolated at all points on a 25 x 25 m grid (82 x 82 ft), and contour maps were drawn from this interpolated or kriged data. The nugget and sill were invariant with direction and the sill was less than the sample variance (15.3 [kg.sup.2] [m.sup.-4]) so our assumption is justified that outlier-free soil movement is a stationary regionalized variable.
Kriged variances violate the requirement of independence because the value of a kriged data point, once its position amongst a set of measured data points is selected, is determined by the set, and thus a dependent variable of a function.
