Resumo

The main reason of urban flooding in the Brazilian cities is the deficient urban planning, which includes the design of the drainage systems and the occupation of the land in the watersheds. The urban floods are sources of socioeconomic problems to the local population. They can propagate diseases and offer risk to people's lives in the affected areas. The aim of this study is to develop a computational model to perform simulations of different flood scenarios. A case study was carried out for the district of Porta do Céu in the city of Maringá-PR, Brazil. Field data was collected and the inconsistencies were corrected. The model was implemented by using Bentley® SewerGEMS® v8i software. Three scenarios were analyzed and the results demonstrated that the current drainage network is underestimated. However, it is possible to execute structural and non-structural measures for flood mitigation in the region.
