Estimation of hydraulic conductivity by using pumping test data and electrical resistivity data in faults zone

open access: yesEcological Indicators, 2021
Obtaining hydraulic properties is crucial for describing the transport of groundwater and pollutants in the faults area. In this way, the spatial distribution of hydraulic conductivity plays a major role in expressing the heterogeneous flow and non ...

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.
