The present research is performed to collect information about the presence, location and characteristics of sand and gravel in “Kriva bara” field and also its possible expansion. For this purpose is used one of the most high-resolution geophysical methods - electrical resistivity tomography (ERT). This is a geophysical technique for imaging sub-surface structures from electrical resistivity measurements made at the ground surface. The results illustrate the potential of electrical resistivity methods to separate different layers and monitor the subsurface based on electrical resistivity. This method proved to be very effective in mediums with comparatively different electrical resistivity properties and also offers non-destructive survey of the investigated area which is a key element in the modern geophysical prospection. |
