Vertical Electrical Sounding - a Continuous Approach

1st EEGS Meeting, 1995
The electrical profiling method is a powerful technique for mapping the near-surface geology. The increasing need for detailed and fast investigations of the protective clay caps of aquifers has renewed the focus on the method.

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

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 ...

Model curves for vertical electrical sounding over 2D structures

53rd EAEG Meeting, 1991
Vertical electrical sounding is one of the most used electrical methods in Geophysical Prospecting and its application is restricted to those problems according to structures that do not differ strongly from stratified media. Even in these situations the simplicity of a near one dimensional earth approach is sometimes not reached and some important ...

Detection of animal tissue thickness using simple vertical electric sounding (VES)

Physiological Measurement, 1997
Tetrapolar linear arrays are commonly used in geophysics to explore the vertical distribution of resistivity values in a geological section of a specific point on the earth. This technique, known as vertical electric sounding (VES), uses different electrode configurations.

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 ...

Reducing ambiguities in vertical electrical sounding interpretations: A geostatistical application

Journal of Applied Geophysics, 2007
AbstractThe Vertical Electrical Sounding (VES) is the most widely used geophysical technique for groundwater prospecting. Howeverits interpretation has been subjected to several indistinctness and efforts are on to tackle them. Vertical Electrical Soundings werecarried out at 86 sites in a small watershed of about 60 km 2 in a granitic terrain with 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 ...

On the resolving capability of vertical electric dipole soundings

SEG Technical Program Expanded Abstracts 1989, 1989
An extremely high resolving capability of both direct current (DC) and transient electromagnetic (TEM) soundings using a vertical electric dipole (VED) source is shown. In contrast to conventional surface methods, electric, magnetic and EM fields generated by a VED are sensitive to the presence of very thin layers, even in the case of moderate ...
