In the process of operation of hydraulic structures it is needed to study these structures for their technical condition, which affects the durability and other structures operational properties. Some defects are impossible or difficult to examine. This is due to the lack of open access for visual inspection. Such defects are cavities formed under reinforced concrete slabs, which protect the dam from erosion. Timely detection and elimination of cavities during repairs extends the service life of dams. Scientifically confirmed methods are proposed, by means of which the problem of finding the location and the volume of cavities under reinforced concrete of ground dams, dams and other hydraulic structures is solved. The research proves that with using the natural pulsed electromagnetic field of the Earth geophysical method it is possible to interpret in terms of the cavities which occur during the inspection of the reinforced concrete fastening of the upper slope of the dams. The authors propose to determine the depth of anomalies by the color of the equal level of the natural pulsed electromagnetic field of the Earth, which corresponds to the depth of the cavities obtained by the method of geoelectric tomography.
