This paper reports the results of hydraulic modelling under unsaturated condition at the domain around openings in argillaceous rock formation at the Tournemire site, France, in order to determine permeability value suitable to explain measured distribution of saturation ratio. We performed modelling with finite element method with consideration of seasonal changes of humidity in the openings. Results of modelling could simulate reasonably well the characteristics of the measured distribution. Modelling results with permeability 10 $^{-19}$ m $^{2}$ to 10 $^{-20}$ m $^{2}$ show good agreement with the measurement results. This study is a part of works for Task C of the DECOVALEX-THMC project.
