The absorption curve was represented with the empirical model of van Genuchten whose parameters were calculated on the absorption curve measured at equilibrium. The conductivity curve was calculated by using the model...

... ABSTRACT: A database is described that contains results of laboratory measurements of hydraulic conductivity and associated soil properties performed on compacted clay samples from two Belgian landfills. The measurements were conducted on a base liner of one landfill and a capping liner...

..., bentonite (B) and kaolinite (K) mixes were investigated as possible replacements. One-dimensional consolidation tests performed on these mixes revealed that B:K mix of 50:50 was similar to pure bentonite from the point of view of hydraulic conductivity (k). Direct hydraulic conductivity tests were conducted...

Leachate chemical analysis before and after percolation shows that soil modifies leachate pH and electrical conductivity. The percolation of leachate...

... (1000+ years) hydraulic barriers for radioactive and mixed waste sites. Existing data demonstrate that asphalt concrete barriers and fluid-applied asphalt layers can provide extremely low hydraulic conductivities (<1x10–11 cm/s). On-going research results show that asphalt may have the robust...

Tests results showed indicated that if the hydrated GCL is after hydration by pure ethanol, the GCL hydraulic conductivity may be increased significantly but not dramatically. Conversely, in case of unhydrated GCL, the hydraulic performance...
