MEASURING OF RESERVOIR DEPTH BY METHOD OF CHARACTERISTIC OSCILLATIONS
Presented standard methods to control water level of water body. Study of aftermath of recession of level Lake Sevan (Armenia) have discovered a law of frequency modulation of characteristic oscillations of water basin by function of water depth. We offer the method of direct measurement of water level based on the solution of the inverse problem. We offer the remote measurement method too, which use analysis of vibrations of the basin floor of seiches origin. Remote measurement provides the possibility of multi-channel monitoring by the use of time division, frequency division and space division of vibrations of different reservoirs floors. This is expedient for the remote measurement of water level in distant reservoirs, the information about which may be limited. In addition, we offer presented law for solution of other engineering tasks - seismic tomography, increasing power output of hydropower plants, controlling shifts mode in fragments of seismic-active faults.
