Activation of natural-destructive processes in the territory of Kazbegi municipality (Devdoraki glacial-mudflow case study).
2016
There is considered the nature of contemporary mudflows; the mudflow centers of the past have been revealed through the mudflow materials remaining in the gorges and it was possible to determine their distribution boundaries. In recent years (2006, 2010, 2012), in the conducted works in Kazbegi region and published papers, in which the glacial-mudflow action developed in the Devdoraki gorge is considered, the idea on their origin conditions, natural destructive risk mitigation and their neutralization is suggested. The recommendations underline the conduction of sectoral monitoring in the mudflow origin areas. Nevertheless, we will try to speak up about the glacial-mudflow developed in the Devdoraki gorge on August 16_17, 2014, which has led to the natural-destructive phenomena in the Tergi River gorge. In order to collect the additional material and explore the geographical environment of the gorge, we once again went through the Devdoraki gorge. As a result of personal observations and generalization of materials, authors came to the conclusion, that the mudflows in the Devdoraki gorge have a long history of centuries. Besides, the stages of recurrence according to periods is known, which is gradually reduced; it is possible, that similar cases occur in the future; therefore, it is necessary to conduct a range of activities based on the findings, which will minimize the possibilities of floods and destruction action of the Devdoraki mudflow.
