On the influence of the spatial distribution of fine content in the hydraulic conductivity of sand-clay mixtures

open access: yesEarth Sciences Research Journal, 2018
Sand-clay mixtures are one of the most usual types of soils in geotechnical engineering. These soils present a hydraulic conductivity which highly depends on the fine content.

Effect of entrapped air on hydraulic conductivity in quasi-saturated porous media

open access: yesShui kexue jinzhan, 2019
The groundwater flow with entrapped air was termed as quasi-saturated flow. The entrapped air in quasi-saturated flow of aquifer had a significant influence on hydraulic conductivity of porous media.

Relationships between hydraulic traits and habitat preference for six Acer species occurring in the French Alps [PDF]

open access: yes, 2004
Xylem hydraulic properties and vulnerability to cavitation were studied in six Acer species which occur, in the French Alps, along a soil moisture gradient from the moist valleys to the drier mountain stands.

Hydraulic Conductivity of Rock Masses Surrounding Water Curtain Boreholes for Underground Oil Storage Caverns

open access: yesEnergies, 2021
The assessment of the groundwater flow rate around the cavern periphery is a critical requirement for the design of underground water-sealed oil storage caverns and commonly made through seepage analysis, where a reasonable estimation of the hydraulic ...

In situ mixing of organic matter decreases hydraulic conductivity of denitrification walls in sand aquifers

open access: yes, 2008
In a previous study, a denitrification wall was constructed in a sand aquifer using sawdust as the carbon substrate. Ground water bypassed around this sawdust wall due to reduced hydraulic conductivity.

Comparison of Hydraulic Conductivity Values Obtained from Empirical Formulae and Laboratory Experiments

open access: yes, 2020
Hydraulic conductivity determination plays an essential role in the investigation of groundwater flow regime which can then influence many field problems such as pumping capabilities in the area, transport of contaminant or heat and soil internal erosion.

A pH‐Based Pedotransfer Function for Scaling Saturated Hydraulic Conductivity Reduction: Improved Estimation of Hydraulic Dynamics in HYDRUS [PDF]

open access: yes, 2019
Hydraulic conductivity is a key soil property governing agricultural production and is thus an important parameter in hydrologic modeling. The pH scaling factor for saturated hydraulic conductivity (Ks) reduction in the HYDRUS model was reviewed and ...
