Estimating Relative Hydraulic Conductivity from the Water Release Characteristic of a Shrinking Clay Soil

To understand the hydraulic properties of soils, accurate prediction of unsaturated hydraulic conductivity is needed which is commonly derived from the soil water release characteristic. In fine-textured soils the modified Mualem-van Genuchten (MMVG) function has been used extensively to predict the change in relative conductivity with changes in matric potential, but this assumes that the soil...

Least Squares Estimation of Hydraulic Conductivity from Field Data

In this paper, we present some numerical results of the determination of ow parameters in a groundwater model. The data used in this parameter estimation is from the MADE experiments conducted on Columbus Air Force Base. Our results are based on least squares cost functional with a nite diierence scheme used to solve the ow equation.

Determination of Hydraulic Conductivity Based on (Soil) - Moisture Content of Fine Grained Soils

ring size dependence of field saturated hydraulic conductivity measurements in a clay loam soil

field saturated hydraulic conductivity (kfs) is one of the most important soil properties that considerably contribute to soil quality. however, specifically in the structured soils, the measurement of kfs is difficult and time-consuming. therefore, verifying the simple and fast methods for kfs measurement is needed for effective soil monitoring. this study was conducted to investigate the effe...

Comparison Of Hydraulic Conductivity Test Methods for Landfill Clay Liners

Accurately measuring the in situ hydraulic conductivity (permeability) of a clay liner is a major factor in the construction of landfill containment systems. Laboratory and large-scale field test methods are often utilized on test pads constructed prior to placement of the production liner to determine the hydraulic conductivity of the clay. While these test methods provide reliable results, th...
