Abstract

Summary

The goal of this paper was to examine the distortions caused by bodies out of profile line in Electrical Resistivity Tomography (ERT) survey. Analogue modelling with Wenner array was applied. Results of 2D inversion has proven to be highly affected by lateral range issue, while quasi-3D inversion was significantly less distorted. For surveys conducted in vicinity to resistive body high amplitude anomaly was observed. When resistive body was four times the electrode spacing away from the survey line the 2D inversion was not significantly affected by the body's presence. For quasi-3D inversion there were no significant false anomalies observed.
