The accelerated urbanization process of many Brazilian cities can generate a series of socio-environmental problems for the population, as well as many challenges for the institutions and bodies responsible for management, planning and spatial planning. Changes in the geomorphological patterns of rivers, the removal of riparian forest, the occupation of its bed, pollution and contamination of river channels all contribute to the process of degradation of water resources. This degradation scenario can accelerate the frequency and intensity of floods. When we talking about the floods that occur in the metropolitan region of Rio de Janeiro, we understand that is an urban socio-environmental problem, which causes a series of consequences and damages for the affected population. In Nova Igua?u, a municipality belonging to the RMRJ, it can be said that the interaction of natural and anthropic factors contributes to the occurrence of floods. The city registers high pluviometric indexes in the summer period and is inserted in a geomorphological context of lowlands, presenting many flooded areas that have been deforested for urban occupation. The Botas River, one of the main rivers in the municipality, is frequently hit by flood events and suffers from the impacts related to urban occupation on its banks, waste disposal and discharge of raw sewage. With that, the main objective of this research is to analyze the perception of risk to floods of the residents who live in the stretch of the Botas River, located between the Comendador Soares and Ouro Verde neighborhood, in Nova Igua?u. The research methodology is divided into five stages, where we first build a State of the Art of research on the perception of risk to floods and on the Botas River. In a second step, we held a discussion on the concepts used in the theoretical framework (risk, risk perception, vulnerability, resilience, watershed, flood, flood, flooding and natural disaster). In the third moment, a characterization and contextualization of the study area was carried out, through the analysis of social and natural aspects (geomorphology, hydrography, coverage and land use, climatology). In the fourth stage, field work was carried out to conduct interviews with residents who live in the vicinity of the Botas River stretch located between the Comendador Soares and Ouro Verde neighborhoods. The fifth stage constituted the process of analyzing the perception of risk of residents, based on the methodology of Textual Discursive Analysis (DTA) by Moraes and Galiazzi (2006; 2016), in which the results and discussions were presented. It can be considered that the residents perceive the risks of flooding, many report in their speeches that they feel fear when it starts to rain and the residents realize that floods usually occur in the months of December, January and February, that is, in the rainy season of the study area. Therefore, it is assessed that the risk is perceived by the subjects, but it is accepted due to the residents' relationship with the place, the experiences they had throughout their lives in relation to floods, in addition to the benefits that are inherent to the occupation, such as the ease of transportation to the center of Nova Igua?u via train, van or bus, the security of the place in relation to crime and violence, and the proximity to commercial establishments.
