Chapter 7. the Effect of Variability in Hydraulic Conductivity on Contaminant Transport through Soil-bentonite Cutoff Walls
ثبت نشده
چکیده
There are applications of barrier technology where the variability in hydraulic conductivity from point to point in the barrier, in addition to the average hydraulic conductivity of the barrier, is important. Throughout this chapter, the following application will be referred to in order to demonstrate this point: use of a circumferential soil-bentonite cutoff wall to completely enclose a contaminated area of the ground, accompanied by groundwater extraction from within the enclosure to produce an inward hydraulic gradient.

Soil hydrau-physical data are important for many hydrological modelings. They are the main variables controllingthe key processes such as water and chemicals movement and transport in the soil profiles. This study was conductedin order to analyze the spatial distribution of selected soil hydrau-physcial characteristics including infiltration rate(IR), saturated hydraulic conductivity (Ks), bulk...
متن کاملConsequences of Electromagnetic Stimulation on Hydraulic Conductivity of Soils
Hydraulic conductivity is a measure of the rate at which water flows through porous media. Because of the dipole properties of water molecules, any electric field can affect hydraulic conductivity. In this study, the effect of radio-frequency (RF) waves on hydraulic conductivity is investigated. This is important both for the geophysical measurement of hydraulic conductivity as well as remediat...

Making use of concrete materials in cut-off walls, because of their low permeability and standing high Hydraulic Gradient caused by underground drainage, has attracted great amount of attention. Using ordinary concrete with high elasticity modulus, compared to other materials may accompany with problems including brittleness of cutoffs due to dynamic stresses. To solve this problem, adding a ce...
