This paper presents a method to estimate the additional storage capacity derived from the
presence of a capillary break or barrier beneath a soil layer used in a surface cover system …

Accumulating data on traditional compacted soil-surface covers are demonstrating that they
are likely to degrade and have reduced effectiveness as long-term barriers; therefore …

Unsaturated drainage layers (UDLs) have been demonstrated to greatly increase the lateral
diversion capacity of capillary barriers. The inclusion of a UDL allows native soils suitable for …

The behavior of frost-susceptible soils is analyzed using finite-element solutions for water
flow, heat and solute transport in one dimension. These solutions take into account the …

This paper presents a comparison of numerical simulations to the measured response of
capillary barrier field tests. The simulations were of pilot-scale tests of four 7 m long, 1.2 m …

A combination of a parallel fracture model with the PHREEQC-2 geochemical model was
developed to simulate sequential flow and chemical transport with reactions in fractured …

The effect of immobile water content on contaminant advection and dispersion in
unsaturated porous media has been studied using a formulation which assumes that even in …

Laboratory data were utilized to verify the finite-element program MELEF for simultaneous
water flow, heat and solute transport simulations in saturated-unsaturated porous media …

A conceptual model is developed in this article that accounts for the effect of slow and fast
moving liquid zones on solute transport in porous media. The liquid phase within the porous …

A mathematical model solved by finite elements method namely MELEF-3v model, is used to
simulate the one-dimensional water flow as well as the heat and the mass transport through …
