Resumo: | Soil proofng and absence of tree cover produces more volume of surface runoff, enlarges the peak flow and reduces the delay time. The search for alternatives to reduce the volume of surface runoff in urban areas is important to get the hydrological answers to the problems caused by the urbanization process and, along with that, to reduce the risk of flooding. This article proposes to estimate the reduction of runoff and the delay in the peak flow caused by the presence of three species of trees (Mangifera indica, Tabebuia ochracea and Licania tomentosa) in urban areas. This allowed the quantifcation and the performance analysis of tree species in reducing urban runoff; the arboreal parameters correlated with the flow capacity reduction; and examined whether there is reduction and delay in the peak flows. The benefts from the interception of storm water for trees need to be pondered and guaranteed in afforestation master plans and urban drainage in order to reach the mitigation of damage caused by the neglect of urban water. For this, level sensors were used (limnigraphs) to quantify the surface runoff in areas with and without the presence of arboreal coverage, and in experimental structures set on waterproof, semipermeable and permeable soil. For events with an average value of gross precipitation of 17.1 mm, the presence of arboreal individuals caused an average time delay up to the peak flow of 3 minutes, an average reduction of peak flow of 0.8 mm/min and it contributed to an average reduction of surface runoff of 4.7 mm/min. |

A busca por alternativas para diminuição do volume de escoamento superficial em áreas urbanas é importante para obter respostas hidrológicas aos problemas ocasionados pelo processo de urbanização e, com isso, amenizar o risco de inundação. Este estudo se propôs a estimar a redução do escoamento superficial e o atraso no pico de vazão ocasionados pela presença das árvores de três espécies (Mangifera indica, Tabebuia ochracea e Licania tomentosa) no meio urbano, o que permitiu a quantificação e análise do desempenho de espécies arbóreas na redução do escoamento urbano; correlacionou os parâmetros arbóreos com a capacidade de redução do escoamento; bem como averiguou se há redução e atraso nos picos de vazão. Os benefícios provenientes da interceptação das águas pluviais pelas árvores precisam ser ponderados e garantidos nos planos diretores de arborização e de drenagem urbana, de modo a alcançar a mitigação dos prejuízos provocados pelo descaso com as águas urbanas. Para isso, foram utilizados sensores de nível (linígrafos) para a quantificação do escoamento superficial em áreas com e sem a presença da cobertura arbórea, e em estruturas experimentais instaladas sobre solo impermeabilizado, semipermeável e permeável. Em eventos cujo valor mediano de precipitação bruta foi de 17.1 mm, a presença dos indivíduos arbóreos ocasionou um atraso mediano no tempo ao pico de vazão de 3 minutos, uma redução do pico de vazão de 0.8 mm/min e do escoamento superficial de 4.7 mm/min.Universidade Federal de Santa Maria2019-04-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2582010.5902/1980509825820Ciência Florestal; Vol. 29 No. 1 (2019); 193-207Ciência Florestal; v. 29 n. 1 (2019); 193-2071980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/25820/pdfCopyright (c) 2019 Ciência Florestalinfo:eu-repo/semantics/openAccessAlves, Patrícia LayneFormiga, Klebber Teodomiro Martins2020-06-05T19:47:21Zoai:ojs.pkp.sfu.ca:article/25820Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2020-06-05T19:47:21Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
