Revisiting the operation of large-scale hydroegineering facilities

Summary

Unique hydroengineering facilities built in 1960–1980-ies in the USSR for the purpose of water supply, electrification and amelioration are described. Proposals on improving the design, construction and operation of the hydroengineering schemes are presented. The problems in operating large-scale hydroengineering schemes conditioning the need to conduct scientific research works and, consequently, additional capital and operational expenses are substantiated. At present because of numerous technogenic threats and natural disasters the following tasks have to be fulfilled: ensuring the safety of water reservoirs in case of seismic events; reliable operation of the hydroengineering facilities (large-scale pumping stations, hydroelectric power stations, water reservoirs etc.) under the conditions of the widespread water level decline in the rivers; upgrade and equipment replacement at the hydroengineering facilities. Involving graduate students from technical higher educational institutions in processing the data obtained for the long-term operation of the large-scale hydroengineering schemes with the purpose of gaining professional skills is proposed.
