Groundwater investigation in Kuala Selangor using vertical electrical sounding (VES) surveys

Environmental Geology, 2006
Integrated geoelectrical and hydrochemical surveys were used to investigate and delineate different types of groundwater in the Kuala Selangor alluvial aquifer. Previous hydrogeological borehole investigation showed that this aquifer contains several types of groundwater in relation to its salinity. The high salinity of the groundwater in some areas is

Joint inversion of Surface Nuclear Magnetic Resonance and Vertical Electrical Sounding

Journal of Applied Geophysics, 2002
The method of Surface Nuclear Magnetic Resonance (SNMR) provides a very new technology to directly determine subsurface water distribution. The microscopic magnetization of water molecules is used to derive water content and pore size information from SNMR soundings.

SOME IMPROVEMENTS IN THE INTERPRETATION OF VERTICAL ELECTRIC SOUNDING CURVES*

Geophysical Prospecting, 1986
ABSTRACTThe process of VES interpretation is discussed, including the following points.(a) Preliminary interpretation by means of master curves. It is shown that the positions of the auxiliary points K and Q depend on the resistivity of the substratum.

A new method of geoelectrical prospecting by vertical electric current soundings

Journal of Applied Geophysics, 1996
Abstract Some advantages and problems of a new geoelectrical prospecting method, vertical electric current soundings (VECS) are discussed. This method is based on using a new source, circular electric dipole (CED). The source is installed in the following way. One of the transmitter poles is grounded in the central point.

Pulled Array Continuous Vertical Electrical Sounding (PA‐CVES) with an Additional Inductive Source

Symposium on the Application of Geophysics to Engineering and Environmental Problems 1996, 1996
Electrical and electromagnetic profiling methods are used extensively in environmental geophysical investigations for many different purposes. The PA-CVES method (Pulled-Array Continuous Vertical Electrical Sounding), where a tail of electrodes is towed behind a small vehicle while continuously measuring in many electrode configurations, has been used ...

About Measurement of Vertical Component of Electric Field During Magnetotelluric Sounding

2019
In magnetotelluric sounding (MTS), variations of five components of electromagnetic field are usually registered. With the standard approach in experiment transfer functions are defined as ratios between horizontal components of electric and magnetic fields. Deviations from the Tikhonov-Cagniard basic model are defined by the fifth registered component—
