VES vertical electrical sounding is one of the most popular and reliable geophysical technique applied for exploration and environmental study. VES survey results reflect the variations of resistivity in geological medium up to several dozen meters depth. Geo-electrical resistivity methods are fast and non-intrusive geophysical techniques of ground research. Surveys consists in the measurement of the resistivity of the rock formations and allow for the separation of areas differentiated in terms of resistivity. Measurements provide information about the geological structure down to a depth of several dozen meters. Especially the distinction between high and low resistivity complexes/zones is possible.
