Conference Paper

Analysis of the Urban Drainage System: Case Study of the Stormwater Galleries at the intersection of Rua Governador Nei Braga and Avenida Brasil in the city of Umuarama-PR

Presented in XVII Safety, Health and Environment World Congress

This early conference paper examined a local urban drainage problem in Umuarama, Brazil, using a real intersection as the case study. It framed stormwater galleries as practical infrastructure whose performance depends on field context, design assumptions, and local flood pathways, setting the stage for later work on urban flood diagnosis.
