Flood Risk Assessment and Management

In recent years União da Vitoria and Porto União have suffered severe floods, after a long period of normal to low floods. The important economic losses and psychological impact generated a great deal of discussion and studies about their causes. The population blamed the backwater effect of the Foz do Areia dam for the impact of the floods. This fact caused a major conflict, that lasted more than ten years, between the population and the state power company, owner and operator of the dam. This paper presents the main flood causes, the dam impact and the structural and non-structural measures studied in order to cope with the problem.
