REGULARITIES OF NATURAL AND ANTROPOGENIC HAZARDOUS PROCESSES DEVELOPMENT FOR SOLOTVYNO (TRANSCARPATHIA, UKRAINE)

Abstract

The consequences of the rock-salt resources usage in Solotvyno, the causes of technogenic environmental emergency situation, activity of governmental structures and the participation of international experts to overcome it are considered. The developed zoning scheme of hazardous geological processes and their consequences are represented. This scheme, constructed in the ESRI software, have been provided basing on expert assessment: former hazardous events frequency and scale, changing of topography and geomorphology, geodetic survey, remote sensing data (satellite imagery, Differential Interferometric Analysis data), authors systematic field observations, coupled with summarized previous research results and monitoring studies of terrain altitude in various years, by different methods and a number of research teams. Zones cover territories ranked by the probability of subsidence, sinkholes formation (ground surface collapses), landslides, karst, suffosion, erosion, floods, flooding, increased mineralization of aquifers used for water supply, etc. The presented scheme is proposed as the basis for ensuring life safety in Solotvyno during the territory development and monitoring system establishment, and then based on the monitoring results obtained, the scheme will be improved, detalized and acquire a predictive focus. Therefore because of the complicated geoecological situation, development and functioning of a permanent geoecological monitoring system for the Solotvyno salt dome structure and adjacent territories is a priority objective.
