Resumo: | The loss of natural vegetation and the increase of impermeable surfaces due to the urban expansion have shown that the traditional urban drain systems are ineffective and not much adaptable to the changes of ground use. One of the consequences is the increase of the speed of runoff, which furthers flood, with great material and environmental damage. The flood usually occurs because of stormwaters. The aim of this essay was to study the modular green roofs contribution, submitted to storms, 155mm/h lasting 7,0 minutes, in retention and delay of runoff. Besides, values were determined for these rain-flow classic model parameters: Rational method (C) and CN (SCS), which will be used for hydrological modeling of the effects of using green roofs to control urban flood. The methodology used is experimental and involved building worktops with adjustable inclination to support the experimental modules and a system for controlled induction of rain intensity. Three modular system models were studied for green roof which allow the storage of water at the bottom of the tray that the modules are made up, two are 17,0 L (M-17 and F-17) and one is 4,0 L(M-4), in dry soil and moist conditions. In each vegetated module three species of vegetation were used: Portulaca oleracea, Callisia repens e Apnia Cordfolia. The results show that the retained volume, calculated through observing the runoff, in different situations, are coherent with each other and have data reported in literature. The vegetated modules produced the best results with dry soil and the worst results with moist soil. The average percentage of retention, considering all the types of modules, was 58% of the total volume of induced water, with a 12 minute average delay on runoff. The average values of C (Rational method) were 0,4; 0,48; 0,36, to modules M-17, M-4 and F-17, respectively and the ones for CN (SCS) were 93, 95, 93, to the same modules. As expected, the greatest CN values were the ones for moist ground, keeping the relation of lesser retained volume and more runoff and CN. The module F-17 presented better performance in all aspects (flow reduction, hydric retention, runoff delay). This study shows the good contribution this kind of system may provide for retention and delay runoff, even for short duration heavy rains, mainly after dry season, common situation in places with tropical weather. Future studies should assess the green roof s performance of modular systems accounting other characteristics and types of rain s intensity. Adopting green roofs must be cautious, especially the extra burden that such a system is. |

Uma das consequências disso é o aumento da velocidade do escoamento superficial (runoff) que favorece as inundações, com enormes prejuízos materiais e ambientais. As inundações ocorrem geralmente quando ha ocorrência de chuvas de alta intensidade. O objetivo deste trabalho foi estudar a contribuição dos telhados verdes modulares submetidos a chuvas de alta intensidade, 155mm/h com duração de 7,0 minutos para retenção e retardo do escoamento superficial. Além disso, foram determinados valores para parâmetros de modelos clássicos chuva-vazão: Método Racional (C) e CN (SCS), que poderá, futuramente, servir de modelagem hidrológica dos impactos da adoção de telhados verdes no controle das enchentes urbanas. A metodologia adotada foi de natureza experimental e envolveu a construção de bancadas com inclinação regulável para suporte dos módulos experimentais e um sistema para indução de chuvas com intensidade controlada. Foram estudados três modelos de sistema modular para telhado verde que permitem o armazenamento de água no fundo da bandeja que compõe os módulos, sendo 2 de 17,0 L (M-17 e F-17) e 1 de 4,0 L (M-4), nas condições de solo seco e solo úmido. Em cada módulo vegetado foram utilizadas 3 espécies de vegetação: Portulaca oleracea (Onze horas), Callisia repens (Dinheiro em penca) e Apnia cordfolia (Rosinha do sol). Os resultados demonstraram que os volumes retidos, calculados a partir da observação do runoff, nas diferentes situações, foram coerentes entre si e com dados relatados na literatura. Os módulos vegetados produziram os melhores resultados com solo seco e os piores resultados com solo úmido. O percentual médio de retenção, considerando todos os tipos de módulos, foi de 58% do volume total de água induzida, com retardo médio de 12 minutos no runoff. Os valores médios de C (Método Racional) foram 0,4, 0,48, 0,36, para os módulos M-17, M-4 e F-17, respectivamente e os de CN (SCS) foram 93, 95, 93, para os mesmos módulos. Conforme esperado, os maiores valores de CN foram para solos úmidos, mantendo a relação que quanto menor o volume retido, maior o runoff e o CN. O módulo F-17 foi o que apresentou melhor desempenho em todos os aspectos (redução do escoamento, retenção hídrica e retardo do runoff). Este estudo demonstra a boa contribuição que esse tipo de sistema pode proporcionar na retenção e retardo do escoamento superficial, mesmo para chuvas intensas de curta duração, principalmente após período de curta estiagem, situação comum em locais de clima tropical. Futuros estudos deverão avaliar o desempenho dos sistemas modulares de telhados verdes com outras características e intensidades de chuvas. A adoção de telhados verdes deve ser cautelosa, sobretudo pela carga extra que esse tipo de sistema representa.Submitted by Boris Flegr (boris@uerj.br) on 2021-01-06T14:12:31Z No. of bitstreams: 1 Claudia Maria Loiola do Nascimento.pdf: 4321087 bytes, checksum: 4e9e8bc761ab8ce370f06d9ea6c11479 (MD5)Made available in DSpace on 2021-01-06T14:12:31Z (GMT).
