Abstract
Summary
The present work deals with the application of ERT method inside a karstic cave in Macedonia, North Greece. The cave geometry is incorporated as a priory information to 3D inversion software and the results are evaluated with forward modelling of simple realistic 2 layer models. The effect of the resistive walls and ceiling of the cave is investigated and the artefacts are discussed. Finally, the results of the 3D inversion are compared with the results of a typical 2D inversion of the same data, ignoring the 3D environment of the cave.
