Acesso em: 28 dez. 2022.e - 2179-0612http://repositorio.bc.ufg.br/handle/ri/21695This study aimed to define the flood inundation area of the stream Macambira to implement a linear park. This stream is the subject of a project called Urban Environmental Program-Macambira Anicuns, which aims to transform the banks of these two streams in a public park for the city of Goiania. The stream in question, not different from the others in the urban area, is currently degraded and the floodplain areas occupied by disorderly houses, shops, small industries and plantations. To define the maximum perimeter of the park, its area of coverage, a hydrodynamic study was necessary with the delimitation of flood area of Macambira's urban stream margins, in Goiania, using high-resolution topography and HEC-RAS software. Overall, the flood of band obtained for the study area was flooded in the natural channel of the stream. However, there are overflowing in some points, reaching the streets and places of populated areas, reaching up to 70 meters from the natural channel. Thus, the modeling HEC-RAS allowed contemplate the current diagnosis of the drainage system Stream Macambira, focusing on the hydraulic behavior of the existing drainage channel, providing the basis for the project, so that we can establish effective intervention strategies more appropriate for each situation.porAcesso AbertoÁrea de inundaçãoUrbanização de baciasModelo hidrodinâmicoInundation areaUrbanizationHydrodynamic modelArtigohttps://doi.org/10.5216/reec.V11i1.32101
