ABSTRACT
This study seeks to elucidate technical facets of the Tskneti landslide occurred in June 2015, Tbilisi, Georgia. Unfolding during an extraordinary intense storm on 13-14 June 2015, the landslide originated 10 km west-southwest of Tbilisi. The event resulted in the catastrophic destruction of a significant segment of the Tskneti-Betania highway and a portion of the Akhaldaba road. Subsequently, massive debris flow temporarily obstructed Vere river, leading to the formation of an artificial berm along the riverbed. Due to the substantial hydrostatic pressure resulting from the accumulated water mass, this berm collapsed. Debris flow transportation along the riverbed towards to Tbilisi city centre lead to flash flood and 22 fatalities ensued. The technical underpinnings of the landslide and landslide-induced flood will be evaluated by geological, topographical and hydrological aspects. The remediation approach for the damaged roads will be assessed in geotechnical engineering perspective.
