SUMMARY:

The current context of climate change, which has generated significant social and economic losses for cities, has placed the issue of socio-environmental risks at the forefront in recent years. This scenario presents challenges that unfold into innovations in the ways knowledge is produced regarding actions aimed primarily at disaster prevention and mitigation. In this regard, this study sought to explore the contributions of hydrological–hydraulic modeling as a tool to support the development of community-based risk management processes and climate adaptation in environmentally fragile areas. To this end, the analysis was conducted through a case study of the application of hydrological–hydraulic modeling in the project for developing the Community Risk Management and Reduction Plan for the Sol Nascente Housing Sector—specifically Section 3—located in the Federal District. The study adopted a theoretical approach grounded in two main reflections: (1) critical thinking based on an understanding of socio-environmental risks as social constructs; and (2) sociotechnical integration as a promising pathway for addressing socio-environmental challenges. Accordingly, the methodological design was structured around sociotechnical integration and consisted of the following stages: (i) socio-environmental characterization of the study area; (ii) configuration of the hydrological–hydraulic model, using PCSWMM (Personal Computer Storm Water Management Model) in this study; (iii) identification and delineation of hydrological risks based on current-scenario modeling; (iv) community participation through participatory workshops; (v) simulation of alternative scenarios incorporating different Nature Based Solutions (NbS); and (vi) analysis and discussion of the case study results. As a result, important findings and contributions were recorded regarding the integration between hydrological-hydraulic modeling and community participation for the management of socio environmental risks. It allowed for the analysis of the current situation of the study area, the prediction of the functioning of the drainage network under construction, and the estimation of flow values, as well as the identification of the locations most susceptible to flooding and flash floods. It also made it possible to quantify the reduction in surface runoff volumes in alternative scenarios with the implementation of nature-based solutions (NbS), indicating better intervention strategies. In parallel, the process contributed to empowering the population to face socio-environmental risks and climate change.
