“…The effectiveness of geophysical methods of operational non-destructive testing on an earth dam located in the Sverdlovsk region has been shown for assessing the stability and predicting its physical condition [2]. Examples of integrating geophysical methods, such as electrical prospecting in the modification of electrical tomography and ground penetrating radar profiling, are considered to obtain information about the lithological structure of the dam, identifying possible zones of high humidity and areas of decompaction on an earth dam as part of small hydroelectric power station structures (Karelia) [3]. Conductive zones associated with enhanced water filtration through geophysical monitoring of the reservoir's soil dam were discovered, and the feasibility of conducting seasonal geophysical monitoring for a more reliable assessment of the condition of soil hydraulic structures was noted [4].…”

An integrated approach to analyzing changes in the induced wave field in mining waste storage facilities for mineral waste is considered to localize potentially dangerous zones in the body of bulk structures using georadar sounding. It has been established that the zone of possible water saturation of rocks is perceived by the georadar signal as a transition to a medium with a higher dielectric constant and is reflected by the maximum amplitude of the signal. The boundaries of water saturation zones are not always sharply defined, but change smoothly depending on the degree of water saturation from a natural state unsaturated with moisture to complete saturation of soil pores. During GPR sounding, below the expected zone of water saturation, the soil structure is noticeably smoothed out, where, due to increasing attenuation, the signal amplitude sharply drops, which manifests itself in a noticeable decrease in the contrast of the wave pattern of the radargram. The use of intra-method integration by profiling on a permanent base and a common depth point with simultaneous synchronization of groundwater level measurements in a piezometer made it possible to identify and identify zones of increased water saturation in the dam body.
