The wetting front capillary pressure can be obtained from the integration of the Brooks and Corey equation of relative hydraulic conductivity (Brooks and Corey, 1964), through the expression (Brakensiek, 1977; Rawls et al.
The standard addresses calculating the saturated hydraulic conductivity (Ksat), permeability (k), and porosity (n) of fine-grained soils.
The hydraulic conductivity of the unsaturated soil (K) was estimated by the theoretical model of Van Genuchten-Mualen as described in JONG VAN LIER et al.
The average value of hydraulic conductivity in horizontal and vertical direction is 1.
For the weighting function accounting for the limitations to plant water uptake due to high and low soil hydraulic conductivity, we first estimated the unsaturated hydraulic conductivity function, K(h), for each sample.
In their seminal study of cation effects on soil permeability, Quirk and Schofield (1955) defined the cation concentration low enough to result in a 10% to 15% reduction in the saturated hydraulic conductivity, after leaching with water of known composition for a prescribed time-period, as the threshold concentration (TEC).
As displayed in Figure 6, the hydraulic conductivity of sample A-S jumped to 1.
Earlier reports also highlighted the maximum improvement in hydraulic conductivity of soil with simulated sub-soiling and gypsum-saturated solution (Shahid, 1993).
Variation in saturated hydraulic conductivity with vertical effective stress for crude household waste (Powrie, Beaven 1999)
The soil hydraulic conductivity is an important parameter for quantifying soil water and solute movement and for modeling hydrogeological processes.
1987) as ajoint project with National Water Well Association (NWWA) and US Environmental Protection Agency, for aquifer sensitivity using depth to water table, aquifer material, soil composition, recharge rates, topography, vadose zone and saturated hydraulic conductivity (Shirazi et al, 2013).
