Factors affecting hydraulic conductivity of asphalt mixture [PDF]

open access: yes, 2017
In this paper, the topological properties of air voids in asphalt mixture: air void content, average void diameter, Euler number, genus, enclosed cavities, percolation number, aspect ratio, circularity and tortuosity were analysed using X-ray tomography ...

Hydraulic conductivity of rice roots [PDF]

open access: yesJournal of Experimental Botany, 2001
A pressure chamber and a root pressure probe technique have been used to measure hydraulic conductivities of rice roots (root Lp(r) per m(2) of root surface area). Young plants of two rice (Oryza sativa L.) varieties (an upland variety, cv. Azucena and a lowland variety, cv.

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

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.

Optimization of saturated hydraulic conductivity estimation using kriging in drainage networks

open access: yesApplied Water Science, 2023
Statistical analysis of saturated hydraulic conductivity is the fundamental of engineering plans for water resource projects. In the other words, project solutions and designs depend directly on the accuracy of these statistical analyses and the methods ...

Effect of solid waste landfill leachate contaminants on hydraulic conductivity of landfill liners

open access: yesWater Science and Technology, 2022
Landfilling is one of the most widely used methods to reduce the impact on the environment and human health by ensuring the management of solid wastes. For the process in question to be called landfill, the landfill leachate must be controlled and liner ...

Saturated anisotropic hydraulic conductivity of a compacted lateritic soil

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2018
This study focuses on the saturated anisotropic hydraulic conductivity of a compacted lateritic clayey sandy soil. The effects of the molding water content and the confining stress on the anisotropic hydraulic conductivity are investigated. The hydraulic

Effects of the hydraulic conductivity microstructure on macrodispersivity [PDF]

open access: yesWater Resources Research, 2016
AbstractHeterogeneity of the hydraulic properties is one of the main causes of the seemingly random distribution of solute concentration observed in contaminated aquifers, with macrodispersivity providing a global measure of spreading. Earlier studies on transport of solutes in heterogeneous formations, either theoretical or numerical, expressed ...
