摘要
During 13-14 June 2015 heavy rainfall in the Riv. Vere basin area and its tributaries caused a drastic increase in the water level and triggered/activated large-scale landslide and debrisflow events. This put the Tskneti-Samadlo and Tsnketi-Akhal- daba motorways out of order. Residential buildings and miscellaneous infrastructural facilities, buildings and structures and Tbilisi Zoo located at the low elevations in the Riv. Vere Gorge were significantly damaged or/and totally destroyed. 23 persons died during the disaster. This study presents the results on an analysis of the landslides/ debrisflows in the riv. Vere catchment and discusses main triggering factors of natural disaster, statistics for the prior period, and geodynamic situation of Akhaldaba “big” landslide developed at the Tskneti-Samadlo road section. It is given recommendations for future activities to reduce landslide/debrisflow hazard in this catchment.
