Determination of hydraulic conductivity of a suspension

open access: yesJournal of Hydrology and Hydromechanics, 2013
Abstract The process of sedimentation and subsequent gravity compression of kaolin and water suspensions was investigated experimentally. 45 batch tests were carried out and the time dependence of the height of the suspension column was measured. The one-dimensional equations of Darcian mechanics of two-phase porous media are applied to formulate ...

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.

Prediction of unsaturated soil hydraulic conductivity with electrical conductivity [PDF]

open access: yesWater Resources Research, 2009
Soil hydraulic conductivity (K) varies greatly with matric potential (h) and exhibits a high variability at the field scale. However, this key property for estimating water flux in soils is difficult to measure. In contrast, soil electrical conductivity (σ) is easier to measure and is influenced by the same parameters affecting K.

Hydraulic Conductivity and Landfill Construction [PDF]

open access: yes, 2011
Landfills are important engineered constructions spread all over the world. Their number is calculated in thousands as the production of wastes in Europe only, reaches each year 3000 million tones of which 14% (about 415kg per capita) is municipal waste (EEA, 2004).

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 ...

Evaluation of sand-clay-anionic polyacrylamide blends for alternative compacted clay landfill liner design [PDF]

open access: yesMATEC Web of Conferences, 2021
In this project, an innovative low hydraulic conductivity material for landfill cover and liner construction was studied. The material is a blend of natural clayey soil from Comodoro Rivadavia city (Chubut province, Argentina) mixed with fine uniform ...

Study of Mechanisms Governing Electromagnetic Alteration of Hydraulic Conductivity of Soils [PDF]

open access: yes, 2014
Hydraulic conductivity is a measure of the rate at which water flows through porous media. Because of the dipole properties of water molecules, electric field can affect hydraulic conductivity.
