Abstract: To improve the understanding of the influence of hydraulic properties and rainfall conditions on rainfall infiltration mechanism and hence on the pore-water pressure distributions in single and two-layer unsaturated soil ...

Abstract: A new method and instrument were developed for in situ measurement of the gas diffusion coefficient (Dg) and gas coefficient of permeability (kg) of unsaturated soil. Air containing tracer gas of volumetric concentration ...

Abstract: A mathematical model for calculating gas pressure profiles in layered landfill systems is presented. Solutions to scenarios considering a zero-pressure top boundary condition and a zero gas flux or fixed gas pressure bottom ...

Abstract: This paper presents a laboratory study on electrokinetic dewatering (EKD) of sewage sludge with fixed and moving electrodes. The experiments with fixed electrodes were conducted in two purposely designed Perspex cylinders ...

Abstract: Gas permeability (ka) and gas diffusion coefficient (Dp) are vital for controlling gas transport through earthen landfill cover overlying municipal solid wastes or acid mine tailings. Soil clods generated during the ...

Abstract: This study developed a new method to simultaneously measure gas dispersion coefficient and gas coefficient of permeability (GCP) of an unsaturated soils with due theoretical consideration of steady-state gas transport ...
