Zweidimensionale geoelektrische Inversion als Teil einer integrierten geophysikalischen Auswertung zur Erkundung oberflaechennaher Schichten

Surface wave and geoelectric methods were combined for high-resolution underground exploration in the meter and decameter range. Using the results of surface wave tomography and of the inversion of local dispersion curves for geoelectric model conceptions, the integrated interpretation approach strongly reduces the variety of solutions by improving underground parameterization for the geoelectric inversion. The integrated approach is based on a program for solution of the differential equations of geoelectrics by finite differences. Applying two-dimensional modeling the iterative inversion implemented in the program allows the fitting of exploratory data. Hummel-arrangements are proposed to obtain earth resistivity data of high information content for the integrated treatment. Application of the integrated method has been successfully demonstrated in field studies at the refuse dump Hermsdorf.
