Influence of large water reservoir construction and filling on dynamics of Earth crust local tilts

摘要

It is known that many different types of hazardous influences on the environment may be related to large hydrological structures and water reservoirs. These may be both site-specific, natural hazards as well as manmade, non site-specific hazards. Therefore we aimed to investigate the influence of Enguri High Dam construction and reservoir initial water level variation in West Georgia on the dynamics of local Earth crust tilts. A high arch dam (271.5 m high, 728 m long) was built in the canyon of the River Enguri in 1978, as part of the Enguri Hydroelectric Power Plant. The maximum capacity of reservoir is 1.1 × 10~9 m~3.
