Soil hydraulic conductivity values
WebThe Soil Hydraulic Conductivity Data Set contains soil hydraulic conductivity, ... which varies from .01 to 1.0 [cm^-1], and that for most soils a value of about 0.12 [cm^-1] can be assumed (Dave Elrick, personal communication). Calculated Variables: Saturated hydraulic conductivity, and Matric flux potential. Webeter) was either incorporated into the surface 2 to 3 cm of soil or was dissolved into the leaching water at a rate corresponding to 3.82 t/ha. Six or nine separate water applications of gypsum dissolved into leaching water significantly increased hydraulic conductivity (P < 0.01). Soil hydraulic conductivity increased (P < 0.01) with depth at ...

The results indicated that saturated Porchet and saturated Porchet calculated using Equation (17) are reliable for determination of K s because their values are close to that obtained from the direct method.
WebThe saturated hydraulic conductivity layer represents soils with a value of ≥ 10 micrometers per second in the upper 30 inches of soil, a value typical of sandy soils in Illinois. Saturated hydraulic conductivity is a measure of the ease with which water will move through a soil, and values typically increase with the sand content. WebThe numerical value of the hydraulic conductivity under unsaturated conditions, however, depends on the amount of water in the soil (i.e., soil water content) or how strongly water is held by the soil (i.e., soil water pressure head, h).
