ABSTRACT: Massive landslides occur in southern Saskatchewan. Natural slopes across some glacial valley walls may have failed in the past and are susceptible to movement with slight changes in slope geometry and/or change in groundwater conditions. A landslide on Provincial Highway No. 37, crossing the Frenchman River Valley, was activated in 2003 by fill placement during the realignment of the highway. Remedial construction was completed in 2004. Both piezometric levels in the slope and slope movement have been monitored since the landslide occurred. This paper presents geological and hydrogeological conditions, discusses the results of the instrumentation monitoring program, and provides an update on the groundwater and slope stability conditions of the landslide at Highway No. 37 crossing the Frenchman River Valley.
RÉSUMÉ: Des glissements de terrain massif sont trouvés dans le sud de la Saskatchewan. Les pentes naturelles à travers des parois de la vallée glaciaire ont peut-être échoué dans le passé et sont susceptibles de mouvement avec seulement une modification mineure de la géométrie de la pente et/ou de l'état des eaux souterraines. Un glissement de terrain sur la route provinciale numéro 37, traversant la Vallée de la Rivière Frenchman, a été activé en 2003 par le placement de sol pendant le ré-alignement de la route. La construction réparatrice a été complétée en 2004. Les niveaux de piézomètre dans la pente et le mouvement de la pente ont été surveillés depuis que le glissement de terrain. Ce document présente les conditions géologiques et hydrogéologiques, discute des résultats du programme de surveillance des instrumentations et fournit une mise à jour sur les eaux souterraines et la condition de stabilité de la pente du glissement de terrain à la route 37 traversant la Vallée de la Rivière Frenchman.
