The estimation of flood spreading in urban areas of Ukraine is carried out. Total increase of flood in urban areas of administrative regions of Ukraine is investigated. It is shown that flooding in Ukraine has already become a major factor in ecological and geological complexity of life safety in industrial and urban areas. The most important regions of the country in which flooding has become a significant factor that directly affects the dangerous change of geological environment are determined. In general this creates an additional threat to the security of the population in these areas and can be a determining factor of environmental degradation in cities and town in most regions of the country. It is concluded that during 1998-2014 the impact of global climate change on activation of urban flooding inUkrainehas been growing in the conditions of lack of defensive ability of hydraulic structures against increased level of precipitation and expanding of flooding areas. Grade of administrative regions of Ukraine on the level of growth of urban flooding is offered. Expected socio-economic losses out from urban flooding in Ukraine are assessed. Some of the greatest values of expected loss have been observed within the most industrialized and populated regions ofUkraine. It is shown that urban flooding inUkrainehas already become an additional factor in shaping the nature of man-made threats to the security of urban population of these areas. The complex of measures for reduction of the negative impact of and damage from urban flooding in the conditions ofUkraineare offered.
