Abstract

Electric resistivity tomography is suitaible method for geophysical survey of shallow subsurface subjects. We selected this method for identification of historical roads relicts. We choosed four localities for our study in the eastern part of Bohemia and north-western part of Moravia. Historical roads are detected by well defined vegetation features and the geoelectric cross sections were drawn across them. The relicts of historical roads are visible on cross resistivity sections. They manifest themselves as anomalous objects with diff erent resistivity. The resistivity is mostly higher than surroundings due to their higher compaction. They are located in depth about 1 m and create oval bodies.

Keywords:
