Levashov S.P., Yakymchuk N.A., Korchagin I.N., Pischaniy Yu.M. 

Presented here are the results of practical application of the complex of geoelectric methods of short-impulse electromagnetic field forming (SIEFF) and vertical electric-resonance sounding (VERS), as well as georadar soundings for operative engineering-geological examination of action area. They indicate that the complex allows to select zones with raised soil moistening, to define directions of the filtration water flow migration, to estimate depths of occurrence and thicknesses of watered rock horizon, to define loose sediments thicknesses, gruss and granite basement upper boundaries depths, and to select and trace tectonic fractures. This complex of methods can also be used in monitoring observations on building areas with the purpose of determining the construction projects influence on engineering-geological conditions of the action areas and neighbouring territories.
