Resumo

Environmental problems such as climate change, droughts, erosion, biodiversity reduction and floods are typical examples of problems that are unlikely to have a single solution, and increasingly more critical, requiring continuous monitoring and monitoring in order to ensure an appropriate environment for the community. In this context, the Fuzzy theory emerges as a viable solution to study the uncertainties of a flood propagation prevention system. In this study, seeks to understand the fuzzy diffusive wave flood routing as well as to identify the influence of the hydraulic parameters Manning number and slope, in the membership functions form, both in space and time. In order to find the solution of the "fuzzified" partial differential equations contained in the model, the Finite Differences Method was used, using an implicit scheme and elaborated a computational program for its mathematical solution. From the results generated, it can be observed that the use of fuzzy theory in the fuzzy diffusive wave models can become a viable alternative for the evaluation of uncertainties in regions susceptible to flood propagation.
