FORMATION INITIAL AND BOUNDARY CONDITIONS PROBLEM SOLVING EMERGENCY PREVENTION OF NATURAL ORIGIN, CAUSED BY HYDROLOGICAL AND METEOROLOGICAL PHENOMENA IN CERTAIN REGIONS OF THE HIGHLANDS
Roman Gudak, Serghii Iline, Alexandr Soshinskiy FORMATION INITIAL AND BOUNDARY CONDITIONS PROBLEM SOLVING EMERGENCY PREVENTION OF NATURAL ORIGIN, CAUSED BY HYDROLOGICAL AND METEOROLOGICAL PHENOMENA IN CERTAIN REGIONS OF THE HIGHLANDS Based on a comprehensive analysis of natural and climatic features of the Carpathian region of Ukraine, the initial and boundary conditions for solving the problem of prevention of natural emergencies caused by hydrological and meteorological phenomena in a particular region of the mountain area through the use of rescue helicopters. It is determined that the main feature of the soils of the Carpathian Mountains is their relative looseness and water saturation. With the appearance of additional volumes of aquatic environment, which under the influence of gravity, create significant hydraulic gradients that lead to landslides, mudslides, landslides and races of rivers and streams. Emergencies of a natural nature, which are caused by hydrological and meteorological phenomena, in the mountains have five characteristics. This is the inevitability and sudden onset of a catastrophic event, which can cover a long area, accompanied by great destruction and changes in terrain. Features of emergency management in a particular region of mountainous areas include detailed study of the area and monitoring of local information, geo-information modeling of disasters and early preparation of action plans, constant training of rescuers and preparation for the use of new rescue tools - helicopters. As a result, they form a system of initial and boundary conditions for solving the problem of natural disaster prevention in a particular region of the mountain area, namely: initial conditions for solving the problem - a set of conditions that ensure the fulfillment of orders for delivery to the disaster area and evacuation; boundary conditions - are determined by the maximum load of helicopters, weather conditions, flight time and length of routes, the structure of the graph of the flight task plan and the condition of mandatory return of helicopters to base points. Key words: emergency, mountainous region, helicopter, warning task, initial and boundary conditions
