Geoelectrical Measurements for Agricultural Canal Seepage Detection

Proceedings, 2012
The protection of water resources is a current problem at a global scale, especially in regions where this resource is poorly available. In this respect there is an increased pressure on water managers to improve water use efficiency. The use of geophysical tests as a tool for managing the efficiency of irrigation networks is well documented in ...

Paradoxes of geoelectrics

Izvestiya, Physics of the Solid Earth, 2016
The problem of energy paradoxes revealed in geoelectrics are discussed. The experimental facts illustrating the anomalous energy characteristics of the magnetotelluric (MT) field are presented. An attempt is made to interpret these anomalies from the standpoint of directional analysis. Two three-layer models corresponding to the situation |Q| > 1 and \(

The Geoelectrical Structure of Northwestern Anatolia, Turkey

Pure and Applied Geophysics, 2007
The magnetotelluric method has been employed to generate a geoelectrical model that will reveal the rich geological pattern and dynamic character of western and northwestern Anatolia, Turkey. Magnetotelluric data were collected from 53 sites along a profile of 290 km from the Dardanelles to the Alasehir Graben. Magnetotelluric data were in the range of

The natural geoelectric field

Proceedings of the 2nd International Conference on Bioelectromagnetism (Cat. No.98TH8269), 2002
Our planet is enveloped by an electric field, which is always present, but varies in magnitude. Even though this has been known for several decades, very little attention is being given to this phenomenon. This global electric field is still not fully understood and provides more questions than answers.

GEOELECTRICAL PROSPECTING WITH UNDERGROUNDELECTRODES*

Geophysical Prospecting, 1962
AbstractIn many situations, because of the great influence of a surface layer on apparent resistivity values, the interpretation of electrical soundings may be very indeterminate, according to the “equivalence principle”.For these situations, an arrangement which includes an underground electrode has been proposed.

Examples of geoelectric surveys

Proceedings of the IEE Part A: Power Engineering, 1959
The Introduction deals briefly with the general principles underlying geoelectric methods of surveying and gives a simple formula for the apparent resistivity at a given depth below the surface in a homogeneous medium. The two problems of interpreting the different kinds of curves obtained from field measurements and of determining the depth of the ...

Geoelectric Signatures of Tailing Ponds

Proceedings, 2011
Tailing ponds are seen today both as polluting factors and mineral resource. Investigating their properties, calculating their volumes, evaluating their metal stocks and their acid drainage potential are critical issues both for the industry and the environmental agencies.
