Study on the hydraulic conductivity of Boom clay [PDF]

, 2011
International audienceThe hydraulic conductivity is a key parameter in geotechnical engineering practice for the seepage and consolidation analysis. Experimental results show that the hydraulic conductivity is mainly governed by the soil porosity, and ...

Hydraulic conductivity of rock fractures [PDF]

Transport in Porous Media, 1996
The flow of a single-phase fluid through a rough-walled rock fracture is discussed within the context of fluid mechanics. The derivation of the ‘cubic law’ is given as the solution to the Navier-Stokes equations for flow between smooth, parallel plates - the only fracture geometry that is amenable to exact treatment. The various geometric and kinematic

Modeling of transpiration reduction in van Genuchten-Mualem type soils [PDF]

, 2009
We derive an analytic expression for the matric flux potential (M) for van Genuchten-Mualem (VGM) type soils which can also be written in terms of a converging infinite series.

Unsaturated hydraulic properties of vegetated soil under single and mixed planting conditions [PDF]

, 2019
Effects of plant roots on changes of soil hydraulic properties, including soil water retention curves (SWRC) and soil hydraulic conductivity functions (SHCF), are not well understood, especially when soil is unsaturated and vegetated with multiple plant ...

Surface tension effects on the hydraulic conductivity of hydrophobic porous media

Geoderma
Under certain conditions of natural or anthropogenic origin, the wettability properties of soils change from hydrophilic to hydrophobic. Such a transition results in substantial changes in water flow dynamics and soil hydraulic properties.

Analysis of clogging in constructed wetlands using magnetic resonance [PDF]

, 2011
In this work we demonstrate the potential of permanent magnet based magnetic resonance sensors to monitor and assess the extent of pore clogging in water filtration systems.

Compacted sand-bentonite mixtures for hydraulic containment liners [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2005
Sand is a pervious material in nature. Mixing sand with appropriate bentonite contents yields sandbentonite mixtures having low hydraulic conductivity that can be used as hydraulic containment liners.

A new hydraulic conductivity model of frozen soil considering the hysteresis effect based on fractal theory

Geoderma
The hydraulic conductivity of frozen soil is crucial for predicting water migration and frozen heave. Many models have been proposed to estimate the hydraulic conductivity, which involves factors such as unfrozen water content, specific surface area ...

Impact of spatially varying hydraulic conductivities on tumor interstitial fluid pressure distribution

Informatics in Medicine Unlocked, 2019
This work deals with numerical computation of the interstitial fluid pressure distribution for various synthetic tumor configurations in two spatial dimensions. In order to attend a reasonable degree of realism, we also consider asymmetric configurations

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

Geosciences, 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
