GEOINFORMATION ANALYSIS OF HYDROMETEOROLOGICAL THREATS FOR THE SAFETY OF FUNCTIONING OF THE MAIN LIFE SUPPORT AND ENGINEERING SYSTEMS OF UKRAINE

Ivanyuta S.P., Yakovlev E.O.

Performed in the article is the geoinformation analysis of hydrometeorological threats for the safety of functioning of the main life-support and engineering systems on the territory of Ukraine. These threats are related to the augmentation of rainfall, acceleration of snow melting and the risk of activation landslides, subsidence and other exogenous geological processes. Thereupon it is determined the length of these spatially distributed systems which are located in the areas of the credible forming of flood processes and their enhanceable influence on the initiation of extraordinary situations of engineer-geological origin. The paper shows, that during the last years the main part of extraordinary situations has been catenary (flood-landslides, flood-underflooding) or synergisticall (geochemical contamination-aggressiveness of ground), which worsens the life protection in many regions of Ukraine.

Keywords: geoinformation analysis, main life-support and engineering systems, snow melting, flood and exogenous geological processes, threats, regional estimation.
