Modelagem de bacias de amortecimento de cheias na drenagem urbana da bacia do córrego Ipiranga, Juiz de Fora Minas Gerais

Abstract

This study addresses the growing importance of tackling the challenges posed by climate change as well as extreme events, with a special focus on floods, particularly in the urban context where the Ipiranga Creek Basin is located in Juiz de Fora – MG. The urban environment, complex and interconnected with various systems, presents a series of obstacles in solving these issues. In this sense, the objective is to compare the current urban drainage scenario with a hypothetical scenario that includes mitigation measures, using the Storm Water Management Model (SWMM). From the analysis, with a holistic approach focused on environmental management of water resources and using the SWMM, two scenarios were modeled: the first representing the current state of the basin, without retention reservoirs, and the second a hypothetical scenario where the basin has retention reservoirs to mitigate the impacts of extreme events. The analysis and comparison between the two scenarios showed, as a result of the simulations, a reduction of about 50% in water flow in the basin’s drainage channels, demonstrating the efficiency of these measures in urban scenarios.
