P023 CROSS-HOLE ELECTRICAL TOMOGRAPHY ON A DAM SUMMARY 1 A dam of a water reservoir is investigated by cross-borehole electrical tomography and a geoelectrical survey on the slope. Since the boreholes are dry a new type of pneumatic borehole electrodes was successfully applied. The resolution of different electrode arrays has been investigated. The pole-pole-configuration which provides the largest number of readings has proved to generate the most reliable vertical resistivity cross-section. The resulting images of the other configurations are disturbed by artifacts. The vertical resistivity section of the surface profile can be well extended to greater depth by the results
