Medidas de controle para eventos extremos máximos: uma revisão de literatura

Abstract

Maximum extreme events are becoming more and more recurrent, and one of their aggravating factors is the disorderly urban growth, which harms society itself. Therefore, it is necessary to understand some measures that could be applied to flooding risk areas, to seek the balance between population and hydrological events like these. In face of the existing alternatives trying to control the effects of these phenomena, the present study carried out a literature review about the main concepts related to the extreme events, focusing on the evolution of flood forecasting and warning systems used in Brazil and in the world. From the research, the author concluded that the greatest difficulties about flood forecasting and warning systems are related to the forecast horizon, considering that alerts propagation in time to take action depends on agility and accuracy of the forecasting process.
