mudflows

Over the past 25 years, the western regions of Ukraine have been affected by floods and mudflows caused by a complex of factors, the main of which are climate change, rapid snowmelt and intense precipitation, urbanization and deforestation. These hydrological phenomena caused significant material damage and a threat to human life. To prevent them, the construction of hydraulic structures, strengthening of river banks and afforestation, the creation of early warning systems and improvement of the monitoring system were carried out.

Purpose. The aim of the research is to elucidate the regularity of the mudflow growth processes, depending on the factors that cause them and to the regional time-spatial prognostication of mudflow hazard using GIS. Methods. Using GIS technologies relevant and representative complex of significant factors due to the character of influence has been selected and suggested for usage in the regional prognostication of mudflows hazard. Geological, geomorphological, technological, climatic, landscape factors have been selected as spatial mudflow factors.
