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.

SHALLOW SUBSURFACE STRUCTURES AND QUATERNARY DEFORMATIONS ON THE EASTERNMOST MATANO FAULT, INDONESIA, REVEALED BY ELECTRICAL RESISTIVITY TOMOGRAPHY

open access: yesRudarsko-geološko-naftni Zbornik
In active fault studies, electrical resistivity tomography (ERT) with wide electrode spacing (10 m) and fewer than 60 electrodes is typically utilized. However, this configuration limits the ability of ERT to resolve detailed geological information, such

3D interpretation of helicopter-borne frequency-domain electromagnetic (HEM) data from Ramså Basin and adjacent areas at Andøya, Norway

open access: yesEarth, Planets and Space, 2020
The Ramså Basin is situated on the strandflat on the northeastern side of Andøya between Ramså and Skarstein. It is the only known Mesozoic sedimentary basin onshore Norway and therefore represents an easily accessible analogue to study the setting and ...
