Abstract

Flooding is one of the main social impacts in urban areas, especially in larger, densely impermeable cities. Therefore, developing studies capable of identifying areas that are vulnerable to this type of event is crucial to provide early warning and a quick and effective response to reduce damages. Thus, this study sought to identify areas vulnerable to flood in the Igapó Lake Basin, a densely urbanized area in Lodrina city, southern Brazil. The methodology was based on four main steps: (1) basin characterization, (2) elaboration of the conditioning factors of the flooding by using the analysis hierarchical process (AHP), (3) vulnerability analysis in the GIS environment, (4) and model sensitivity analysis. The parameters considered in this study were as follows: flow concentration, land use, slope, distance from the discharge channel, and altimetry. The proposed methodology has proven to be robust in identifying flood-vulnerable areas. The results revealed that approximately 3.1 km2 (10.3%) of the basin are considered areas of high or very high vulnerability to flood events, affecting many residential buildings, the most abundant land use class in the investigated area. In conclusion, this study sheds light on the intricate interplay between vulnerability to flooding, land use changes, urban development patterns, and resilience measures, offering valuable insights for policymakers and urban planners striving to mitigate the impacts of extreme weather events.
