Cross-hole resistivity and seismic tomography methods are powerful tools for the detection of underground openings of various types. Even in cross-hole measurements, the main disadvantage of the geophysical methods still remains and is the uncertainty of the final interpretation. Joined application of both methods and integrated interpretation, can reduce to some degree this uncertainty. In this study, a novel procedure is proposed for the integrated interpretation of cross-hole resistivity and seismic tomography measurements, based on Unified Geophysical Model (U.G.M) approach and Model stacking Technique. This new processing and interpretation procedure is evaluating for its effectiveness on synthetic examples. The post clustering “full most" models of Arithmetic U.G.M. approach delineate the targets accurately, with greater resolution and with the presence of fewer artifacts. The calculation of correlation coefficient and real rms error indexes proved mathematically the improvement of the post clustering inverted models in comparison to pre clustering inverted models.
