Floods In the context ot natural hazards and risks

Abstract

The worldwide methodology for gathering data about natural disastrous processes is still missing. Consequently it is hard to confirm the theory about increase of natural hazards due to the global warming. Nevertheless data about impact on human lives and property exist. Several specific statements about time and space distribution of floods, effects on different groups of the society allow us to evaluate the risk. The position of floods among various natural hazards is discussed from the point of view of predictibility or occurrence regularity. Internal links between different types of hazardous processes and the role of complexity help to understand the fundaments of floods
