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 ...

Geophysical investigation of the Pb-Zn deposit of Lontzen-Poppelsberg, Belgium [PDF]

open access: yes, 2018
The drillhole information from the Lontzen-Poppelsberg site has demonstrated three orebodies and has allowed the estimation of the extension of the lodes, their dip, and the location at the ground surface.

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.
