The Application of Resistivity Investigations in Archaeology – Two Case Studies from Krakow, Poland

Two examples of the successful application of resistivity measurements for archaeological excavations are shown. Resistivity imaging made on Krakow's historic market square enabled the precise location of an abandoned WWII underground water-tank. For a rough estimation of man-made and natural ground stratification a simplified 1D interpretation of properly (interactively) selected resistivity imaging data was proposed. In the case of the Blessed Salomea Castle in Grodzisko, Krakow, a penetrometer-based resistivity profiling helped in the differentiation of accumulated cultural layers. Resistivity imaging indicated a high-resistivity zone caused by remnants of ancient walls, which was confirmed by further excavations. Information gained from geoelectric research data has helped in excavations as well as further analysis and interpretation of historical events.
