Özet

In this study, the reliability of the resistivity inversion widely used for the investigation of shallow subsurface structures was analysed using modelling techniques. The models used in the study were composed of a buried block and a karstic model with resistive and conductive void. The Schlumberger, Wenner, pole-pole and dipole-dipole electrode configurations widely used in the resistivity method were employed to generate apparent resistivity data and the solutions were obtained by the smoothness-constrained inversion algorithm. 5% Gaussian noise was added to the data from the karstic models. The reliability of the solutions was studied by data and model misfit approaches. It was concluded that the resistivity contrast, level of noise, type of electrode configurations and presence of a layer closed the surface affected the reliability.
