Characterisation of Fractures and Fracture Zones in a Carbonate Aquifer Using Electrical Resistivity Tomography and Pricking Probe Methodes

In the carbonate aquifer, the goal was to determine the location, width and fragmentation degree of the fracture zones and the location, significance and characteristic distance of the fractures. These are fundamental parameters due to their role in the movements of subsurface water , e.g. in hydrogeological modelling of aquifers. However, defining small-scale fracture systems is a difficult task. Two methods proved to be applicable in the test area (Kádárta, Bakony Mts, Hungary) to obtain reasonable details on the fractures: Electrical Resistivity Tomography (ERT) and Pricking-Probe (PriP). PriP is a basic mechanical instrument that has been used successfully in archaeological studies. In this small-scale fracture analysis, ERT outcomes demonstrated its applicability. PriP proved to be a successful organisation, Verification method for both fracture zone mapping and fracture detection, but it provided distinct results in some areas than the ERT. Therefore, the applicability of this approach has yet to be checked, although its problems most likely derive from human activity that reorganises the distribution of the nearsurface debris. Both methods showed fracture zones, including a very characteristic one and a number of individual fractures, at the test site and calculated their characteristic distance and significance. Both methods have proven to be capable of even individually generating hydrogeologically important parameters, but their simultaneous application is recommended to reduce the potential discrepancies.
