Project Description

The project includes the preparation of the inventory map of slope instabilities in the scale of 1: 25,000 and on this basis maps of susceptibility to sliding on an area of ​​about 850 km2 in the mountainous environment, through which passes the Georgian Military Road, which is the main connecting line to Russia and not only for Georgia, but also for the neighbouring countries - Armenia and Azerbaijan. Furthermore, two pipelines go through the area of interest, one with a diameter of 750 mm and the other with a diameter of 1200 mm. Another problem that this project is apiring to address is the endangerment of settlements by slope instability and as a consequence the depopulation of the territory and migration of the population primarily to the capital Tbilisi. Based on the experience of the Czech Republic a database for storing information about slope instabilities will be developed, including interconnection with the map, so that each slope deformation appears in the map with all available information. The database will be ready for publication on the website of the NEA, to allow access to both professionals and lay public. However, it will be edited only by the NEA professionals. Based on field mapping several slope deformations will be identified, which will be equipped with monitoring devices and an early warning system. The Georgian specialists will be involved in all phases of the project so that the Czech side could pass them all the experience and know-how, both directly in Georgia or in the Czech Republic.

Aim of the project

The project aims to increase the capacity of the geological section of NEA to prevent danger arising from slope instabilities in the target area, mainly by being able to identify the areas susceptible to sliding based on the newly acquired knowledge and experience with field research and prioritization of slope instabilities, modelling in a GIS interface and active use of new database of slope instabilities, which will be tailored within the project for use in conditions of Georgia. This capacity will find application not only for spatial planning and development in the region, but also to identify places where it is advantageous to initiate preventive measures to avoid damage to the existing infrastructure and loss of population in the affected mountain areas. Last but not least, in connection with the installation of a pilot monitoring system, theoretical and practical knowledge will be passed to the Georgian side on the use of modern monitoring systems and their connection to the early warning system.
