Multielectrode Geoelectrical Tomography for the Quantification of Plant Roots

open access: yesItalian Journal of Agronomy, 2010
The amount and spatial distribution of plant roots are crucial ecological features, and methods based on soil electrical resistivity (r) tomography (ERT) have been proposed for their non-destructive measurement.

Measuring inline velocity profile of shampoo by electrical resistance tomography (ERT) [PDF]

open access: yesFlow Measurement and Instrumentation, 2017
The rheological properties of fluid systems govern the efficiency and quality of a production process. For certain materials, i.e. non-Newtonian fluids, The change in shear rate leads to the change of local viscosity, while the conductivity also changes due to the change in micro-structure of the material by varying shear rate.

Electrical geophysical evaluation of susceptibility to flooding in University of Nigeria, Nsukka main campus and its environs, Southeastern Nigeria

open access: yesJournal of Groundwater Science and Engineering, 2023
Flooding occurs when rainfall exceeds the absorption capacity of soil and causes significant environmental consequences. In this study, electrical resistivity techniques were employed to assess the flood susceptibility of the study area by examining ...

Lithology Of Geothermal Potential Areas Using The Electrical Resistivity Tomography (ERT) Method

open access: yesJURNAL GEOCELEBES, 2023
The rock lithology of the potential hydrothermal area has been studied using Electrical Resistivity Tomography (ERT) in Pungguk Pedaro Village, Bingin Kuning District, Lebong Regency. Field data acquisition uses a stretch length of 480 meters with the MAE X612-EM Geoelectric tool that forms a straight line. ERT method, using Res2dinvx64 software.

Effects of machinery trafficking in an agricultural soil assessed by Electrical Resistivity Tomography (ERT)

open access: yesOpen Agriculture, 2018
Abstract Soil compaction is a serious problem, which is aggravated due to its difficulty to locate and reverse. Electrical resistivity tomography (ERT) is a non-invasive geophysical method that can be used to identify compacted areas, soil horizon thickness and assess soil physical properties. This study assesses the relationship between
