Leachate drainage volume of municipal solid waste landfills: field testing and hydro-mechanical modeling.

The leachate drainage volume (LDV) of municipal solid waste (MSW) landfills is crucial to the operation of leachate treatment plant and development at the leachate level, but there is still a lack of reasonable evaluation methods. In this study, the evaluation methods, including both field measurements and numerical simulations, are proposed and applied in the case study of a MSW landfill in Southeastern China. For field measurements, 23 boreholes were drilled to test the leachate level distribution, and thus to determine the saturated volume (SV) of the landfill.

Full-scale experimental study of methane emission in a loess-gravel capillary barrier cover under different seasons.

The methane emission in a loess-gravel capillary barrier cover (CBC) in winter and summer was investigated by constructing a full-scale testing facility (20 m × 30 m) with a slope angle of 14.5° at a landfill in Xi'an, China. Weather conditions, methane emission, gas concentration, temperature, and volumetric water content (VWC) in the CBC were measured.
