The study of geotechnical properties of landfill waste is relatively new area in geotechnics (soil mechanics in unsaturated state) and offers solutions for efficient and environment friendly design of landfill. The knowledge of movement of liquid (leachate) & gases is becoming essentially vital as well as the settlement behaviour is to be predicted for the post-closure use of the disposal site. The primary characteristics of soil; permeability constant (hydraulic conductivity) and its relationship to overburden pressures was studied in a large-scale permeameter using modelled...
