Methods for Measuring the Saturated Hydraulic Conductivity of Tills [PDF]

open access: yesHydrology Research, 1990
The texture of tills excludes many of the traditional methods for measurement of the saturated hydraulic conductivity. The hydraulic conductivity is scale dependent and for massive relatively homogeneous till a representative sample volume of 104-105 cm3 is suggested. There are no ideal methods for measuring the saturated hydraulic conductivity in till

Predicting the Saturated Hydraulic Conductivity of Clayey Soils and Clayey or Silty Sands

open access: yesGeosciences, 2020
Predictive models able to provide a reliable estimate of hydraulic conductivity can be useful in various geotechnical applications. Since most of the existing predictive methods for saturated hydraulic conductivity estimation are valid only for a limited

Estimation and Scaling of the Near-Saturated Hydraulic Conductivity

open access: yesHydrology Research, 1999
The hydraulic conductivity in structured soils is known to increase drastically when approaching saturation. Tension infiltration allows in situ infiltration of water at predetermined matric potentials, thus allowing exploration of the hydraulic properties near saturation.

Measurement and simulation of the effect of compaction on the pore structure and saturated hydraulic conductivity of grassland and arable soil [PDF]

open access: yes, 2010
Measurements have been made of the effect of compaction on water retention, saturated hydraulic conductivity, and porosity of two English soils: North Wyke (NW) grassland clay topsoil and Broadbalk silty topsoil, fertilized inorganically (PKMg) or with ...

Characterization of stony soils' hydraulic conductivity using laboratory and numerical experiments [PDF]

open access: yesSOIL, 2016
Determining soil hydraulic properties is of major concern in various fields of study. Although stony soils are widespread across the globe, most studies deal with gravel-free soils, so that the literature describing the impact of stones on the hydraulic ...
