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.

Estimation of the hydraulic parameters of unsaturated samples by electrical resistivity tomography [PDF]

open access: yes, 2012
In situ and laboratory experiments have shown that electrical resistivity tomography (ERT) is an effective tool to image transient phenomena in soils. However, its application in quantifying soil hydraulic parameters has been limited.

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.

Uncertainty in the determination of soil hydraulic parameters and its influence on the performance of two hydrological models of different complexity [PDF]

open access: yes, 2009
Data of soil hydraulic properties forms often a limiting factor in unsaturated zone modelling, especially at the larger scales. Investigations for the hydraulic characterization of soils are time-consuming and costly, and the accuracy of the results ...
