Abstract

The object of this thesis is to compare grid sampling schemes for the spatial interpolation method of Kriging, specifically when Kriging is used to predict unsampled locations along a riverbed. The main concern will be finding the optimal grid spacing between samples. Kriging uses an estimated spatial covariance matrix, or variogram, to find the best linear unbiased estimate (BLUE) of contamination at an unsampled location. Since the variogram is a measure of covariance as a function of distance between sampled points, it is important to investigate the effect that sampling location distance has on the method of Kriging.
