Resumo: | Flood maps are an important instrument in the prevention, control and management of floods, as they can define areas of risk. Thus, the present study aimed to map potential flood risk areas in the urban area of Quebrangulo, a municipality located in the state of Alagoas. The mapping was based on population and households data, obtained from IBGE demographic census of 2010, and hydrodynamic modeling performed by the IBER two-dimensional computational model, which provided the floodwater levels that occurred for each locality. Then, with the use of the ArcMap program, we elaborated a risk map with flood spots for the recurrence periods of 5, 10, 25, 50 and 100 years, for two different scenarios. The areas identified with biggest problems in relation to floods are the areas located near the Paraíba River, where the riverine populations are inserted, mainly due to their vulnerability and disordered occupation. |

Dessa forma, o presente estudo teve como objetivo mapear as áreas potenciais de risco de inundação na área urbana de Quebrangulo, município localizado no estado de Alagoas. O mapeamento se deu a partir de dados de população e domicílios, obtidos no censo demográfico do IBGE de 2010, e da modelagem hidrodinâmica, realizada pelo modelo computacional bidimensional IBER, que forneceu as laminas dâágua de inundação ocorridas para cada localidade. Assim, com a utilização do programa ArcMap foi possível elaborar um mapa de risco com manchas de inundação para os períodos de retorno de 5, 10, 25, 50 e 100 anos, para dois diferentes cenários. As áreas identificadas como sendo as de maiores problemas em relação às inundações são aquelas localizadas nas proximidades do rio Paraíba, onde estão inseridas as populações ribeirinhas, principalmente devido à vulnerabilidade e à ocupação desordenada.ABEC2017-05-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/otherapplication/pdfapplication/pdftext/htmltext/htmlhttps://www.revistasg.uff.br/sg/article/view/114310.20985/1980-5160.2016.v11n4.1143Sistemas & Gestão; v. 11 n. 4 (2016): Dezembro/2016; 431-4431980-516010.20985/1980-5160.2016.v11n4reponame:Sistemas & Gestãoinstname:Universidade Federal Fluminense (UFF)instacron:UFFporenghttps://www.revistasg.uff.br/sg/article/view/1143/528https://www.revistasg.uff.br/sg/article/view/1143/540https://www.revistasg.uff.br/sg/article/view/1143/550https://www.revistasg.uff.br/sg/article/view/1143/568Copyright (c) 2017 Sistemas & Gestãoinfo:eu-repo/semantics/openAccessda Silva, Paulo Vitor Ribeiro MarquesJunior, Ricardo Abranches Félix Cardosode Noronha, Gustavo Carneiro2020-05-29T17:31:21Zoai:ojs.www.revistasg.uff.br:article/1143Revistahttps://www.revistasg.uff.br/sgPUBhttps://www.revistasg.uff.br/sg/oai||sg.revista@gmail.com|| periodicos@proppi.uff.br1980-51601980-5160opendoar:2020-05-29T17:31:21Sistemas & Gestão - Universidade Federal Fluminense (UFF)false |
