Modelling Study on the Impacts of BMPs at Riacho Fundo (Brasília, Brazil)

Abstract

High urbanization affects significantly on cities, intensifying runoff and impairing old urban drainage systems, which may cause floods. Solutions analyzed in this study include management of rainwaters in cities by means of mitigation measures. Riacho Fundo drainage network simulation was carried out using PCSWMM software to evaluate the system behaviour. The simulations evidenced the observed high flows and other problems such as system overloading. BMPs were tested in the model to indicate do the stakeholders which measures can lead to better improvements.
