Caracterización geomorfológica y de ocupación del suelo de cuenca en área urbanizada de Juiz de Fora (Brasil) y propuesta de infraestructura verde como agente promotor de calidad de vida y minimizador de inundaciones

Abstract

Floods require interventions by the public authorities to prevent them in the urbanized area of the Córrego Ipiranga Watershed (BHCI) in Juiz de Fora, Brazil. This research analyzes the dynamics of these disorders in the region and points out mitigating actions for implementation in the watershed. Through documentary research and geoprocessing tools, data on hydrology, rainfall, morphology, and land use were collected and generated to characterize the region and point out sustainable interventions and their locations around the Teixeiras and Ipiranga streams, identified as the most impacted in the watershed. Due to the current occupation of the BHCI, it is noteworthy that the proposed actions aim to mitigate the damage, not being able to prevent flooding and inundation, especially in situations of maximum flows. Among the proposed mitigating interventions, permeable sidewalks, rain gardens, and detention basins stand out. If implemented in the watershed — besides improving the communities' life quality — these green infrastructure elements increase soil permeability, thus reducing water accumulation on the surface.
