ABSTRACT: The soil-water retention curve represents the relationship between the pore-water deficiency and the hydraulic state of soils. Studying the SWRCs in the unsaturated state is required since they are linked to the analysis of seepage, shear strength, volume change, etc. This paper investigated the hydraulic retention behaviour of a non-plastic glacial till from northern Quebec. Different scenarios have been tested using a modified Tempe cell at Université de Sherbrooke to assess the hydraulic retention behaviour of the glacial till. It was shown that the specimen preparation techniques, the initial state and compaction efforts could all have an impact on the water storage capacity induced by suction. Moreover, using a void ratio-dependent soil-water retention model, the experimental data were modelled which can be subsequently used to study hydro-mechanical behaviour of soils in the unsaturated state.
