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 anddiscusses 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 hazardin this catchment.
