Integrity of risk indicators of hazardous natural processes (on the example of the Krasnodar Krai)

Abstract

The problem of assessing risk indicators of hazardous natural processes as the basis for sustainable development of the region arises due to the peculiarities of the geological structure of the territory of Krasnodar Krai. The work is based on a comprehensive assessment of the geological conditions of the territory of Krasnodar Krai with the use of a systematic approach. A list of characteristic natural processes that pose the greatest danger to capital constructions was determined: in the mountainous part – erosion processes, on the plain – soil subsidence and associated landforms. Then, schematic maps were compiled and the geological component of the risk (its spatial-areal indicator) was determined. Subsequently, to compare these maps, overlay operations were performed, as a result of which the spatial characteristics of ARC/INFO layers were combined into a new layer and relational join of their attribute data was carried out. Adding the risks of each parameter made it possible to rank the territory into 4 zones according to the degree of integral risk of manifestation of natural processes.
