This study aimed to assess the risk of flooding and propose alternatives for prevention and containment of flood for the river basin Tucunduba Oxbow River, located in Belem, from the development of methodology for hydrological and hydraulic simulation, aiming the sustainability of macro drainage system, and analyze the physical variables of the basin to be used as input data for the mathematical models, will also be presented in full simulation methodologies. The results show the application of the models mentioned, as essential tools for the prevention and containment of floods on urban drainage basins, which suffer direct influence of the tidal regime. Since the prevention and containment of extreme events such as floods, is an essential tool for urban areas subject to climatic accidents due to the amount of lives involved in the process, disease by the collapse of the sanitation system and impairments on buildings , materials and infrastructure assets.
