GIS TECHNOLOGIES IN PROBLEMS OF MODELING AND FORECASTING FLOODS
Urgency of the research. The activation of exogenous geological processes in Ukraine in recent years due to various natural and anthropogenic processes is indeed a threat that raises the question of forecasting and modeling their occurrence. Target setting. In the life of mankind such problems occupy a significant place. These are problems connected with overcoming the consequences of the action of emergency, especially floods, catastrophic flooding and flooding of territories, which are one of the major socio-ecological problems. Actual scientific researches and issues analysis. Studies of floods issues, floods and searching for optimal techniques for modeling the relief, representing its structure with other geographic elements and processes, have been studied by a number of scientists Uninvestigated parts of general matters defining. Today it is more appropriate to spend money on the creation of monitoring systems, forecasting and flood prevention measures, rather than to eliminate their consequences. The research objective. The purpose of the article is to justify ways of modeling and forecasting the development of floods to reduce their impact through geoinformation technologies. The statement of basic materials. To ensure the living conditions of the population in the territory that affected by floods and increasing its ecological safety, it is necessary to determine the extent of flooding in a timely manner. The most difficult problem associated with flood research is the forecasting of the maximum possible values for raising the level and area of flooded land. Since the capabilities of GIS in modeling, managing and integrating spatial information make geoinformation systems a powerful analytical tool to build the floods model of the Kiev region was used ArcGIS software product. Conclusion. Using ArcGIS in the algorithms of geoprocessing models to solve problems of flood forecasting can be used as a fast and visual express analysis.
