Co-kriging for stochastic flow models

- Summary

Abstract

Co-kriging equations for log-transmissivity and heads are derived for a two-dimensional stochastic model. The behavior of the weights as a function of the unknown value of mean hydraulic gradient J are discussed and the procedure is illustrated by studying the ‘screening’ effects of adjacent measurements and added head measurements. In addition, the bias of the estimator for head values is studied when J is also estimated.
