Abstract


Extreme hydroclimatic events have the potential to directly impact society. In this sense, cities end up being more affected by intense climatic episodes, as urban land use land cover bring significant modifications to the surface dynamics of water flows. In light of this, the present research aimed to analyze impactful extreme events and hydroclimatic disasters historically occurring in the Belém River watershed, located in Curitiba, Brazil. This is a highly urbanized watershed that traverses 38 neighborhoods of the municipality, including the central portion of the city. The research conducted a survey of impactful extreme events in the study area (1911-2022) and updated the mapping of urban land use land cover to assess recent changes in ground pavement and its potential to affect the watershed and population. Thus, an analysis and synthesis were carried out within the scope of urban and climatic planning, aiming to contribute to climate risk management in the region, focusing on alerts, mitigation, adaptation, and resilience efforts.
