ABSTRACT
Aiming at assessing the environmental safety of small Kazbegi HPP, we have described the catastrophic-scale mudflow formed as a result of movement of Devdorak glacier in the Gorge of the river Kabakhi (left tributary of the river Tergi) on May 17, 2014, having inflicted significant damage to the hydraulic works of Kazbegi HPP. With the purpose of securing the environmental safety of small Kazbegi HPP and regulating the erosive-mudflow processes inter alia, the performance reliability and risk of breakdown of a new springboard-type structure by considering the dynamic and static loads of the mudflow were specified.
