Electrical Resistivity Tomography Electrical Resistivity Imaging Equipment Electrical Resistivity Meter for Groundwater Vertical electrical sounding What is Vertical Electrical Sounding Survey?
Vertical Electrical Sounding (VES) is by far the most used method for geoelectric surveying, because it is one of the cheapest geophysical method and it gives very good results in many area of interest.
The field measurements technique is adjustable for the different topographic conditions and the interpretation of the data can be done with specialized software, with a primary interpretation immediately after the measurements. The results of VES measurements can be interpreted qualitatively as well as quantitatively. The quantitative interpretation, in the case of mineral exploration, can give the chance to evaluate the reserves in a certain area of interest.
What the principle about Vertical Electrical Sounding Survey?
The principle of this method is to insert a electric current, of known intensity, through the ground with the help of two electrodes (power electrodes - AB) and measuring the electric potential difference with another two electrodes (measuring electrodes - MN). The investigation depth is proportional with the distance between the power electrodes.
Vertical electric sounding method, as all geophysical methods, needs for a good interpretation the presence of a contrast in resistivity. As the contrast is greater, the results are better.
