Vertical electrical sounding data inversion using continuous ant colony optimization algorithm: A case study from Hassi R'Mel, Algeria

open access: yesNear Surface Geophysics, 2022
Among the existing geophysical methods, the vertical electrical sounding remains a fast and economical way to detect groundwater resources. However, the interpretation of the vertical electrical sounding data often suffers from non-uniqueness due to the ...

Piezometric surface deduced from vertical electrical sounding data [PDF]

open access: yes, 2017
In hydrogeological studies the knowledge of the water table is very essential. In this work, one hundred and eight vertical electrical soundings were carried out, with the view of unravelling the hydrogeological characteristics of Kuri River Basin, Kaduna, Nigeria.

Continuous vertical electrical sounding

First Break, 1988
Vertical e1ectrical sounding (VES), the most important geophysical technique for groundwater exploration to date, has in practice been limited to point observations. High-resolution seismic reflection is currently being developed rapidly, offering the hydrogeologist continuous sections with very precise and detailed information.

Recognizing the Permafrost by Vertical Electrical Sounding

Near Surface 2008 - 14th EAGE European Meeting of Environmental and Engineering Geophysics, 2008
The aim of measurements was determination of the permafrost in the Slovak Tatra mountains and recognation of shallow geological construction. Measurements were carried out in the Copper Valley which is a fragment of the Kazmierska Valley. Very good conditions to collect the snow and to convert it into firn ice was created putting and forming the ...

Recording the Vertical Component of the Electric Field in Magnetotelluric Sounding

Russian Geology and Geophysics, 2020
Abstract —Magnetotelluric sounding (MTS) usually records variations in five components of the electromagnetic field. Interpretation of distorted MT responses of an inhomogeneous earth may be problematic. The problem can be solved by recording additionally the vertical component Ez of the electric field in order to improve the quality of ...

3D Imaging Archaeological Tomb By Vertical Electric Soundings

18th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2005
Application of geophysical methods has increased to investigate near-surface horizons of interests in related to environmental and engineering geophysics because geophysical methods are cost-effective and large areas can be quickly surveyed at relatively low cost without borings and trench excavations. The most productive geophysical methods are Ground

Correlation of vertical electrical sounding and electrical borehole log data for groundwater exploration

Geophysical Prospecting, 2010
ABSTRACTWe have correlated the longitudinal unit conductance CL obtained from interpreted vertical electrical sounding data with the formation resistivity Rt and the formation resistivity factor F, obtained by carrying out electrical borehole logging. Interpreted geophysical data of eleven soundings and two electrical borehole log records are used for ...

Vertical Electrical Sounding (VES) of Chukchi Sea Ice

2018
Vertical electrical sounding (VES) surveys were performed on the Chukchi Sea ice near Utqiagvik (ne’ Barrow), AK in March, 2018, using a capacitively coupled resistivity array. The purpose of this study was to determine the effectiveness of the VES method in determining the thickness of the sea ice and potentially the depth to the sea floor.
