Resumo: | The search for solutions in stormwater management has been a constant in human history. Being a well discussed topic nowadays, public agencies seek for quick solutions in order to minimize the catastrophes caused by floods in result to rapid and disorganized urbanization. Thus, the search for solutions in stormwater management is necessary for maintaining the quality of life, the environment and especially the preservation of the hydrological cycle. Furthermore, infiltration alternatives such as bioretention, trenches and swales have been shown as feasible and well accepted options because they minimize the negative effects of urbanization seeking to restore the natural water cycle. In Brazil, there are few studies focused on design criteria, operation and service-life of these structures, which are important data for the scale of a bioretention otherwise, would be leading to an oversized, costly and underused construction. The main purpose of this study is to analyze the sizing criteria for bioretention systems proposing suggestions for its implementation in the geomorphological conditions of the Santa Maria / RS region. The research evaluates the infiltration structure built in 2010 at the Universidade Federal de Santa Maria (UFSM). The performance of two sizing methodologies was analyzed and the dimensions were compared to the dimensions of the structure implemented at UFSM. The methodology consists of collecting infiltration data from infiltration tests recommended by NBR 13969/97, with some modifications in order to simulate a real event, data of monitoring bioretention at UFSM from 2011 to 2013, and data obtained in the stress test applied to the structure in December 2015. From these data, Horton infiltration curves for the average conditions were adjusted and inserted into the concept of unit infiltration rate (mm.h-1.m-2).The sizing was based on the analyzed methodologies (Curve-Envelope Method and LID method), after the results were compared to the actual behavior of the real structure suggesting adjustments. The results of this study indicate that the methodologies analyzes oversize the bioretention structure. From the analysis of the built bioretention behavior history it can be concluded that despite having smaller dimensions than those obtained through other methodologies sizing, it is effective to storage the drained volume. Therefore, it is clear that the lateral area and the hydrostatic pressure are important to the functioning of the structure, but also the soil-plant relationship, with the creation of preferential paths that end up improving infiltration over the service-life. Further studies are recommended in order to incorporate these items in sizing methodologies, and monitoring of similar structures in order to determine whether the behavior presented by the bioretention is default or an exception. |

Atualmente tem gerado muitos debates, agentes públicos procuram soluções rápidas no intuito de amenizar as constantes catástrofes em decorrências das enchentes e inundações, fruto de uma urbanização acelerada e desorganizada. A busca por inovações se faz necessária para a manutenção da qualidade de vida, do meio ambiente e principalmente pela preservação do ciclo hidrológico. Alternativas de infiltração como biorretenções, trincheiras e valas de infiltração tem se mostrado como opções viáveis e de aprovação geral porque amenizam os efeitos negativos da urbanização buscando restaurar o ciclo hidrológico natural. No Brasil, ainda são poucos os estudos voltados aos critérios de dimensionamento, funcionamento e vida útil das referidas estruturas, que são dados importantes para o profissional dimensionar uma biorretenção, caso contrário, estaria levando a construção de obras superdimensionadas, onerosas e subutilizadas. O objetivo deste trabalho é analisar os critérios de técnicas de dimensionamentos para sistemas de biorretenção e propor sugestões para sua aplicação nas condições geomorfológicas da região de Santa Maria/RS. A pesquisa teve como base a estrutura de infiltração construída, em 2010, na Universidade Federal de Santa Maria. E neste estudo, buscou-se analisar o desempenho de duas metodologias de dimensionamento comparando as dimensões com a estrutura implementada na UFSM. A metodologia utilizada consistiu na coleta de dados de infiltração a partir de: ensaios de infiltração recomendados pela NBR 13969/97, com algumas modificações visando simular um evento real; de dados coletados no monitoramento da biorretenção da UFSM no período de 2011 a 2013 e dados obtidos no Teste de estresse aplicado na estrutura em dezembro de 2015. A partir desses dados, ajustou-se as curvas de infiltração de Horton para as condições médias e inseriu-se o conceito de taxa de infiltração unitária (mm.h-1.m-2). Procedeu-se ao dimensionamento através das metodologias analisadas (Método da Curva-Envelope e Método do LID), após foram analisados os resultados dos dimensionamentos com o comportamento real da estrutura construída no campus Sede da UFSM sugerindo ajustes. Com base nos resultados obtidos neste estudo, os dimensionamentos apresentaram dimensões maiores do que o existente, porém, na análise do histórico da biorretenção construída indica que ela está funcionando perfeitamente no quesito armazenamento. Assim, consta-se a importância da área lateral e da pressão hidrostática no funcionamento da estrutura, como também, a relação solo-planta, com a criação de caminhos preferencias, que acabam melhorando a infiltração ao longo da vida útil. Sendo recomendados novos estudos com o objetivo de incorporar estes itens nas metodologias de dimensionamento, e monitoramento de estruturas semelhantes afim de verificar se o comportamento aqui encontrado é o padrão ou uma exceção.application/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia CivilUFSMBREngenharia CivilBiorretençãoTaxa de infiltraçãoDimensionamentoCurva de hortonBioretentionInfiltration rateDesigning criteriaHorton infiltration curvesCNPQ::ENGENHARIAS::ENGENHARIA CIVILCritérios de dimensionamento de biorretençõesDesigning criteria for bioretentionsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisPiccilli, Daniel Gustavo Allasiahttp://lattes.cnpq.br/3858010328968944Poleto, Cristianohttp://lattes.cnpq.br/8672929134273036Silveira, Geraldo Lopes dahttp://lattes.cnpq.br/1014384740728586http://lattes.cnpq.br/8538706372517163Cadore, Regina Cera3001000000034005003003003001c2baa5d-393c-455f-a5e2-fb47cd900c30069c056b-abc3-4728-ad67-cb96fc6322d49034f37c-d16f-4fc7-ade9-5f67d40864bca59cb24e-bf58-4d81-8b79-cbda2eb9db67info:eu-repo/semantics/openAccessreponame:Repositório Institucional Manancial UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALCADORE, REGINA CERA.pdfapplication/pdf5304940http://repositorio.ufsm.br/bitstream/1/7917/1/CADORE%2c%20REGINA%20CERA.pdf10b8ccac3a280b21d404364c565ff83aMD51TEXTCADORE, REGINA CERA.pdf.txtCADORE, REGINA CERA.pdf.txtExtracted texttext/plain162280http://repositorio.ufsm.br/bitstream/1/7917/2/CADORE%2c%20REGINA%20CERA.pdf.txt00d4efacc70bef210fbe294b51ddd9b2MD52THUMBNAILCADORE, REGINA CERA.pdf.jpgCADORE, REGINA CERA.pdf.jpgIM Thumbnailimage/jpeg4262http://repositorio.ufsm.br/bitstream/1/7917/3/CADORE%2c%20REGINA%20CERA.pdf.jpg8bb417e7817871e3b59167d096c5500eMD531/79172022-04-05 09:29:31.168oai:repositorio.ufsm.br:1/7917Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestouvidoria@ufsm.bropendoar:39132022-04-05T12:29:31Repositório Institucional Manancial UFSM - Universidade Federal de Santa Maria (UFSM)false |
