Flood risk assessment and management: review of concepts, definitions and methods

Rok, strany: 2013, 23 - 44

The article brings a brief overview of the current concepts, definitions and methods of flood risk assessment and management. The modern concept of flood risk assessment is based on combination of flood hazard, probability and potential negative consequences of floods for human health, economic activities, the environment and cultural heritage. An assessment of flood hazard is focused on the estimate of annual maximum discharges for different nonexceedance probabilities and establishment of the corresponding flooding area and specific parameters of flood (water level, flow velocity, etc.). Analysis of expected negative consequences of floods is based on the concept of vulnerability of social, economic and environmental systems. Methodological aspects of hazard dependent vulnerability and hazard independent vulnerability assessment are also briefly outlined. Two approaches are analysed for optimal methodology combining flood hazard and vulnerability. The first expresses the absolute flood risk by the value of the overall average annual damage. The second lies in expression of flood risk in a relative way by an ordinal scale. The integrated flood management is based on the mix of strategy to reduce flooding, strategy to reduce vulnerability to floods and strategy to mitigate the negative consequences.
