This article presents material about the flood on the Vere River on 13-14 June, 2015. It caused significant economic and ecological damage to the country, and there were also human victims. The reasons for the ecological disaster are evaluated and appropriate hydrological calculations have been carried out. It has been particularly established that the predictable (forecasting) maximal discharges of 0,1% value for Vere River is 520 m3/sec and not 410 m3/sec, that was calculated water conduct tunnels in the entrance of city before the Mtkvari River. The flood on the 13-14 June 2015 and the connected tragedy was caused by high intensive precipitation in the catchment basin, the activation of geodynamic processes, and also anthropogenic factors. In our opinion, a reason of disaster also was a design flaw in hydrotechnical buildings (tunnels) – they are not able to manage a water flow rate of 0,1% assurance. The paper presents the recommendations necessary for us to avoid, or at least reduce, the ecological and economic problems caused by floods and debris flow. The presented recommendations against a disaster like that which affected Tbilisi, as well as the expected environmental problems on territory with similar natural conditions, will enable us to avoid or reduce damage caused by flood and debris flow.
