Measurements of Unsaturated Hydraulic Conductivity Functions of Two Fine-Grained Materials

Effective Unsaturated Hydraulic Conductivity

Steady-state and transient one-dimensional unsaturated flow in vertically stratified porous media are examined. Saturated hydraulic conductivity and the alpha parameter of the exponential hydraulic conductivity function were assumed to vary from soil layer to soil layer. The use of effective unsaturated hydraulic conductivity to compute matric potential in the soil profile is demonstrated. Resu...

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

Field Determined Variation of the Unsaturated Hydraulic Conductivity Functions Using Simplified Analysis of Internal Drainage Experiments

Experimentally determined values of unsaturated soil hydraulic conductivity are presented for an Alfisol of the county of Piracicaba, S.P., Brazil. Simultaneous measurements of soil water content and pressure head are made along a 125 m transect within an irrigated field during the internal drainage process. Calculations of the soil hydraulic conductivity were made using the instantaneous profi...
