Simulação de dimensionamento de rede de drenagem urbana convencional em diferentes cenários de tempo de concentração (Tc) e uso de técnicas compensatórias

Abstract

This study informs the problem of flooding in urban regions, highlighting the growing concern due to the increase in extreme rainfall events, resulting from climate and environmental changes. This has given rise to a debate about the need for improvements in the urban drainage system and flood control. The study performs a brief analysis of the conventional engineering approach to scale urban drainage works, highlighting the efficiency of a sustainable drainage system that uses cisterns, micro reservoirs and detention basins. These innovations aim to reduce the negative impacts of urbanization on the hydrological cycle. It is important to emphasize that the study highlights the importance of the debate on rainwater management in the face of climate change and recurrent flooding. With this in mind, compensatory techniques are currently emphasized for their effectiveness in solving these problems.
