ABSTRACT

 

Monitoring of the hydro-regime environment near large reservoirs has great significance for providing their stability, reliability of the relating to them water-engineering constructions, and also for the ecological protection. If the surface drain waters from reservoir and the expiration from it are determining without difficulties, then the determination of filtration into the underlying rocks and back presents great difficulties because of their insufficient accessibility for the appropriate measurements. For the last case it’S possible in principle to accomplish this monitoring remotely by the geophysical methods, especially of electro-magnetic and seismic survey. The advantage of geophysical methods consists in fact in their high mobility. At their usage there is no need to carry observation of the level of underground waters in the bore holes, whose necessary number must be very large for obtaining of sufficient details of data about the underground waters. Besides boring a large quantity of bore holes is relatively labor-consuming, expensive, occupying much of time, and also is harmful to the environment. Geophysical methods here are a supplement to classical hydrological and hydro geological ones.
