Abstract

Indicator simulation technique is one of the most useful methods to grasp heterogeneity of the permeability of the ground. In this paper, the several covariance matrixes which are needed in this method, and the different scattergram between the permeability and the soft data are examined. By using the resistivity tomography and the fracture density as the soft data, the interference tests are simulated and the responses at the observation points are compared to examine the accuracy of the model. The followings are found as the results: the best prediction is given by the model using calculated covariance matrix, even if the weak correlation between the permeability and soft data are used.
