Abstract

Summary

The study proposes the use of a geo-information approach to assess the quantitative manifestation of exogenous processes in the territory of the Kyiv-Pechersk Lavra and the nature of their impact on the state of historical objects. The method includes the creation of a database of several blocks (natural, anthropogenic) in the geoinformation system ArcGIS; the input data were processed by the method of square-by-square assessment of the territory and statistical analysis of data.

The resulting mapping scheme is based on a point integral assessment - for a certain unit square the vulnerability assessment of the territory is a “logical sum”, according to which the unit square belongs to one of the three types of geological environment in terms of potential hazard. Hazardous engineering-geological processes and conditions are represented by a point gradation of relevant parameters.

According to the modelling results, 30.9% (10 ha) of the territory of the Lavra is located in the zone of moderate hazard, 6.3% (2.1 ha) in the zone of potential hazard, where the manifestation and conditions of more than five dangerous engineering and geological processes intersect, and 62.8% (20.4 ha) in the zone of relative safety.

The Near and Far Caves, the Church of the Nativity of the Virgin Mary, the Church of the Annunciation, the Church of the Holy Cross and other architectural sites, which are part of the national heritage of Ukraine and UNESCO, are at risk of being affected by several hazardous engineering and geological processes. These sites are recommended for preventive measures to reduce the impact of hazardous processes.
