... in the unsaturated soil, and this information will be integrated into an effective stress analysis to interpret the nonisothermal pullout results. The tests in this study were performed using a thermo-mechanical pullout device originally developed by Carpenter et al. (2015) that was updated to perform...

...). The GCBD was developed as a means to remove water from unsaturated soils. The transport layer removes water under negative pressures, the capillary barrier stops upward and downward unsaturated flow of water from adjacent layers, and the separator prevents underlying soil from intruding into the capillary...

..., with no available pathways for water to flow. Figure 3. Typical WRCs for different geotechnical materials (after McCartney et al. 2005) Understanding of the concepts of water flow in unsaturated soils has gained added relevance in landfill design because of the increased number...

... GCL Water retention curve Suction Unsaturated soil A geosynthetic clay liner (GCL) is a composite geosynthetic material. It commonly consists of a thin bentonite clay layer (typically of the order of 5–10 mm thick) that is either bound by needle-punched geotextiles or bonded...
