Resumo: The urbanization process results in a reduction of permeable areas, generating a reduction in the infiltration rate and consequent increase in flow rainwater, intensifying the frequency and magnitude of flooding. However, the use of green roofs has been proving to be an efficient practice in reducing and delayed this flow. In this sense, we sought to identify the optimal textural class for the substrate of a green roof submitted to the climatic conditions of the Metropolitan Region of Recife (RMR). Then, the Hydrus-1D model was calibrated and validated using the volume drained by a green roof prototype. Then simulations of the soil water flow with different textural classes were made. After validation, a good efficiency of the model was verified in the representation of the observed values. Finally, the textural classes that presented the highest average retention capacities were sandy loam, loam, silt loam and silt. Therefore, for the studied region, the green roof substrate should be composed of one of these soil categories. In the absence of them, sand, loamy sand, silty clay loam or clay loam should be employed.

Sin embargo, el uso de techos verdes ha sido una práctica eficiente en reducción y retraso de este flujo. En este sentido, buscamos identificar la clase textural óptima para el sustrato de un techo verde condiciones climáticas de la Región Metropolitana de Recife (RMR). Para ello, el modelo Hydrus-1D fue calibrado y validado con el uso de volumen drenado por un prototipo de techo verde. Luego se hicieron simulaciones del flujo de agua del suelo con diferentes clases texturales. Después de la validación, se verificó una buena eficiencia del modelo en la representación de los valores observados. Por último, las clases texturales que presentaron las mayores capacidades medias de retención fueron franco arenoso, franco, limo y franco limoso. Por lo tanto, para la región estudiada, el sustrato de techo verde debe estar compuesto por una de estas categorías de suelo. En ausencia de ellos, se debe emplear arena, areno franco, franco arcillo limoso o franco limoso.O processo de urbanização acarreta a diminuição de áreas permeáveis, gerando uma redução na taxa de infiltração e consequente aumento do escoamento das águas pluviais, intensificando a frequência e a magnitude dos alagamentos. Contudo, o uso de telhados verdes vem se mostrando uma prática eficiente na redução e retardo desse escoamento. Nesse sentido, buscou-se identificar a classe textural ótima para o substrato de um telhado verde submetido às condições climáticas da Região Metropolitana do Recife (RMR). Para isso, realizou-se a calibração e validação do modelo Hydrus-1D com uso do volume drenado por um protótipo de telhado verde. Em seguida foram feitas simulações do fluxo de água no solo com diferentes classes texturais. Após a validação foi verificada uma boa eficiência do modelo na representação dos valores observados. Por fim, as classes texturais que apresentaram as maiores capacidades de retenção média foram a franca arenosa, franca, franco siltosa e silte. Com isso, para região estudada, o substrato do telhado verde deve ser composto por uma dessas categorias de solo. Na falta das mesmas, devem ser empregadas a areia, areia franca, franco argilo siltosa ou franco argilosa.Research, Society and Development2021-05-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1540110.33448/rsd-v10i5.15401Research, Society and Development; Vol. 10 No. 5; e57710515401Research, Society and Development; Vol. 10 Núm. 5; e57710515401Research, Society and Development; v. 10 n. 5; e577105154012525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/15401/13733Copyright (c) 2021 Camila Barrêtto Rique de Barros; Willames de Albuquerque Soares; Marco Aurelio Calixto Ribeiro de Holandahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess Barros, Camila Barrêtto Rique de Soares, Willames de AlbuquerqueHolanda, Marco Aurelio Calixto Ribeiro de 2021-05-17T18:20:49Zoai:ojs.pkp.sfu.ca:article/15401Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:13.907971Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
