The results of experimental and analytical investigations of the movement of lighter than
water organic liquids in the vadose zone are presented. The experiments consisted of …

Most liner systems for hazardous or municipal waste disposal facilities include a compacted
clay layer. The performance of this layer is evaluated based on its hydraulic conductivity …

Deposits of clean sand have been found to show an increase in stiffness and strength with
time both in the field and in the laboratory. This phenomenon is known as' aging'. The …

Polyenergetic, high-photon-flux X-ray absorption methods promise to make possible rapid,
high-resolution measurements of phase fractions in multiphase systems. Improved statistical …

Numerical models have been developed by past researchers to simulate the migration of
light nonaqueous-phase liquids (LNAPLÕs) in porous media. The purpose of this research …

Restoration of aquifers contaminated with denser-than-water non-aqueous phase liquids
(DNAPLs) such as trichloroethene (TCE) presents a significant remedial challenge. The …

Water infiltration into soils has typically been modelled with numerical or analytical solutions
of Richards' equation that require extensive parameterization of soil properties. The …
