Hydraulic conductivity of polymer matrices
Biophysical Chemistry, 1989We demonstrate that the chondroitin sulfate proteoglycan exhibits enhanced sensitivity to the flow of water compared to other macromolecules which is in accord with their functional role in conferring compressive resistance to cartilage. In order to understand factors that may contribute to its low hydraulic conductivity, a comparative study of ...

Hydraulic conductivity of compacted zeolites
Waste Management & Research: The Journal for a Sustainable Circular Economy, 2013Hydraulic conductivities of compacted zeolites were investigated as a function of compaction water content and zeolite particle size. Initially, the compaction characteristics of zeolites were determined. The compaction test results showed that maximum dry unit weight (γdmax) of fine zeolite was greater than that of granular zeolites.

Practical Issues in Imaging Hydraulic Conductivity through Hydraulic Tomography
Groundwater, 2007Abstract Hydraulic tomography has been developed as an alternative to traditional geostatistical methods to delineate heterogeneity patterns in parameters such as hydraulic conductivity ( K ) and specific storage ( S s

Hydraulic Conductivity Of Rockfill
Journal of Hydraulic Research, 1978Dimensionless equations for the hydraulic conductivity of crushed rock and river gravel have been developed on the basis of approximately 1250 permeameter tests. Experimental data of a number of researches were used in the correlations. Grain sizes varied from .55 to .79 mm and pore Reynolds numbers were in the range of .001 to 20,000.

DEPTH DEPENDENT HYDRAULIC CONDUCTIVITY
Soil Science, 1970THE VOID RATIOS OF SOILS DEPEND UPON THE CONSOLIDATION PRESSURE, AND HENCE IT IS EXPECTED THAT WITHIN A GIVEN FORMATION THE VOID RATIO GENERALLY DECREASES WITH DEPTH. ANALYTICAL EXPRESSIONS FOR AVERAGE HORIZONTAL AND VERTICAL HYDRAULIC CONDUCTIVITY AND THE HYDRAULIC CONDUCTIVITY RATIO AS A FUNCTION OF AVERAGE VOID RATIO FO A NONHOMOGENEOUS ISOTROPIC ...

Hydraulic Conductivity Assessment
2009From the hydraulic point of view, rock masses are heterogeneous, anisotropous and discontinuous media. As water flow in rocks occurs mainly along discontinuities, the exact knowledge of their distribution and their characteristic parameters is fundamental to finding the features that describe the fluid flow, in particular, as far as the hydraulic ...

Hydraulic conductivity of ischemic pulmonary venules
American Journal of Physiology-Lung Cellular and Molecular Physiology, 1993We report the first determination of lung endothelial barrier properties in ischemic, nonreperfused microvessels. We quantified the endothelial barrier in terms of hydraulic conductivity (Lp) in single pulmonary venules (diameter 20–50 microns) of isolated blood perfused lungs (dog, rat), held at constant inflation pressure (5 cmH2O) with a gas ...

Hydraulic Conductivity Prediction for Sandy Soils
Groundwater, 2004Abstract The potential for petroleum‐contaminated soils to impact ground water is evaluated using the soil leachability model in South Carolina and Georgia. In this model, the Green and Ampt (1911) equation is used to estimate unsat‐urated flow with saturated hydraulic conductivity (

Dentin Permeability: Determinants of Hydraulic Conductance
Journal of Dental Research, 1978A technique is described which permits measurement of the ease with which fluid permeates dentin. This value, the hydraulic conductance of dentin, increased as surface area increases and/or as dentin thickness decreases. It increased 32-fold when dentin was acid etched due to removal of surface debris occluding the tubules.

Multiple Parameterization for Hydraulic Conductivity Identification
Groundwater, 2008Abstract Hydraulic conductivity identification remains a challenging inverse problem in ground water modeling because of the inherent nonuniqueness and lack of flexibility in parameterization methods. This study introduces maximum weighted log‐likelihood estimation (MWLLE) along with multiple generalized parameterization (GP) methods ...
