Hydraulic Modeling of Unsaturated Zones Around Three Openings at the Argillaceous Tournemire Site (France)

Uehara, S. / Kobayashi, A. / Chijimatsu, M. / Ohnishi, Y. / Fujita, T. / Rejeb, A.

This paper reports the results of hydraulic modeling under unsaturated conditions around openings in argillaceous formation at the Tournemire site, in order to determine a permeability value suitable to explain the measured distribution of the saturation ratio. We carried out modeling using the finite element method with consideration of seasonal changes of humidity in the openings. The results of modeling could simulate reasonably well the characteristics of the measured distribution of the saturation ratio. Modeling results with permeability of 10^‐19m² to 10^‐20m² show good agreement with the measurement results. This study is a part of contribution of the Japan Atomic Energy Agency and Kyoto University team to Task C of the DECOVALEX‐THMC project.
