(GRS 235) Ventilation Test at Mont Terri: Geoelectric Monitoring of the Opalinus Clay Desaturation

Klaus Wieczorek, Chun-Liang Zhang, Tilmann Rothfuchs

Between December 2001 and May 2004, a ventilation experiment (VE) was performed in the Mont Terri Underground Research Laboratory (URL) and co-financed by the Commission of the European Communities under contract No. FIKW-CT-2001-00126.
The objective was to investigate the desaturation of consolidated clay formations in consequence of the ventilation of underground openings of a repository in such a formation.
