Integrated Interpretation of RMT Data and Borehole Results on a Waste Site near Cologne

Waste sites are usually characterized by high electrical conductivities compared with surrounding geological structures. The Radiomagnetotelluric (RMT) technique is very efficient in waste disposal exploration. It uses radiotransmitters in the frequency range between 10 kHz and 300 kHz. Two horizontal electric and magnetic field components are measured from radiotransmitters perpendicular to each other. The observed transfer functions (e.g. apparent resistivity and phase data) are interpreted in the same way as it is usually done with magnetotelluric data.
