TWO-DIMENSIONAL INTERPRETATION OF ELECTRICAL TOMOGRAPHY DATA BY RESISTIVITY AND INDUCED POLARIZATION ZondRes2d program is designed for two-dimensional interpretation of electrical tomography data by resistivity and induced polarization method in land, cross-borehole and water cases. Electrical tomography (Resistivity imaging) is technique including both the method of field observations and technology of processing and field resistivity and IP data interpretation. Its feature is multiple reusing as a source and receiver just the same electrodes position, fixed on a profile line. Such approach allows from one hand to work with a modern high-performance instruments, and on the other hand, to apply effective algorithms of modeling and inversion of resistivity and IP data. For interpretation(inversion) of electrical tomography data is used two- and three-dimensional models. It significantly extends the range of electric prospecting solved problems due to sections investigating that are considerably different from «classic» horizontal-layered. Resolution and thus results quality of electrical tomography is closely connected with the number and density of measurements on the site. Their number usually reaches first thousand that is why the question of field measurements efficiency has basic importance and in many aspects defines possibility of practical using of this method. Special instruments with programmed automatic switching of electrodes is applied for reaching of maximum effectiveness of field works.
