Abstract
The problem of the transportation safety for Mtskheta-Stepantsminda-Larsi road is overviewed. The scientific study of glaciers in the Caucasus started in the first half of the 19th century. From that time the terrestrial observations on glaciers were carried out. The outputs of terrestrial observations resulted in different series of various temporal duration characteristics of glaciers due to the difficulties of field works organization. The data received contain uncertainties and have no sufficient resolution in time and space. With the invention of the Earth’s satellites it was determined that satellite remote sensing is the best technology allowing to receive the data with needed regularity both in terms of time and space resolution. The results of various researches show that sometimes the satellite remote sensing data is difficult to interpret and determine needed glacier characteristics. In such cases the data of the terrestrial observations are used for validation of glacier characteristics along with the expert knowledge of corresponding glaciers. This complex approach gives the possibility to adjust glaciers contours and calculate more accurately various characteristics of a glacier. At present the main problem for the safety of the Georgian Military Road in the territory of Georgia is the glacial and hydrological disasters such as ice blocks falls from the Kazbegi glaciations accompanied with the debris, followed by the river bed blockage and natural dam formation, with a consequent break and pass of catastrophic mudflows. The glacial catastrophes of Kazbegi glaciers: Devdoraki, Mna, Gergeti, Abano and Chachi have great impact on Mtskheta-Stepantsminda-Larsi road safety on the territory of Georgia. The biggest catastrophes on the Georgian territory took place due to Devdoraki glacier fell in 1776, 1778, 1785, 1808, 1817, 1832. The Devdoraki glacier listed falls during those years were connected with the pulsation of the glaciers and their increase. In Kazbegi glaciation the environmental disasters occurred in 2002, 2007 and 2014 (twice). It was the result of ice layers movement. Based on the analysis, it was concluded that the creation of the May 17 and August 20, 2014 catastrophic mudflows was not connected with the glacier pulsation.
