Resumo: | Extreme rainfall events are the cause of several tragedies and disorders. Urban drainage is essential to combat these problems. Urban galleries are not always able to absorb all the demand arising from these events, so the greatest ally of these is natural soil. Few studies aim to quantify the contribution of this medium to drainage in urban centers. This study aimed to estimate the necessary dimensioning of storm sewers to solve these problems, using the soil parameters of infiltration rate and the volumetric capacity of rainwater retention, analyzing the water balance in a commercial and academically important area of the city of Recife PE. Granulometry and simple ring infiltration tests were used to model the water balance in the regions of natural terrain in the predetermined area. The soil proved to be a good conductor, being able to absorb daily rainfall of almost 49mm in its own physical limit. The difficulty encountered was the low rates of natural terrain available in the region - 17% of the total, reducing its performance. It was found that approximately 410 l/s would be needed as the necessary flow from the main network of this urban area, to absorb most of the extreme precipitation events. |

El drenaje urbano es fundamental para abordar estos problemas. Las galerías urbanas ni siempre son capaces de absorber toda la demanda derivada de estos eventos, por lo que su mayor aliado es el suelo natural. Pocos estudios pretenden cuantificar la contribución de este medio al drenaje en los centros urbanos. Este estudio tuvo como objetivo estimar el dimensionamiento necesario de las galerías de lluvia para remediar estos problemas, utilizando los parámetros del suelo de tasa de infiltración y la capacidad volumétrica de retención de agua de lluvia, analizando el balance hídrico en un área comercial y académicamente importante de la ciudad de Recife PE . Se utilizaron pruebas de granulometría e infiltración de anillos simples para modelar el balance hídrico en regiones de terreno natural en el área predeterminada. El suelo demostró ser un buen conductor, pudiendo absorber lluvias diarias de casi 49 mm en su propio límite físico. La dificultad encontrada fueron las bajas tasas de terreno natural disponible en la región - 17% del total, reduciendo su rendimiento. Se encontró que se requerirían aproximadamente 410 l/s como caudal necesario de la red principal de esta área urbana, para absorber la mayoría de los eventos de precipitación extrema.Os eventos pluviométricos extremos são causadores de diversas tragédias e transtornos. A drenagem urbana é de essencial relevância para combater estes problemas. Nem sempre as galerias urbanas conseguem absorver toda a demanda oriunda destes eventos, logo o maior aliado dessas é o solo natural. Poucos estudos visam quantificar a parcela de contribuição desse meio na drenagem nos centros urbanos. Este estudo teve como finalidade estimar o dimensionamento necessário das galerias pluviais para sanar estes problemas, utilizando os parâmetros do solo de taxa de infiltração e a capacidade volumétrica de retenção das águas pluviais, analisando o balanço hídrico em uma área comercial e academicamente importante da cidade do Recife – PE. Foram utilizados ensaios de granulometria e de infiltração a anel simples para modelar o balanço da água nas regiões de terreno natural da área pré-determinada. O solo mostrou-se bom condutor, sendo capaz de absorver chuvas diárias de quase 49mm em seu próprio limite físico. A dificuldade encontrada foram os baixos índices de terreno natural disponíveis na região - 17% do total, reduzindo sua atuação. Verificou-se que seriam necessários aproximadamente 410 l/s como vazão necessária da rede principal dessa área urbana, para absorver a maior parte dos eventos extremos de precipitação.Research, Society and Development2021-06-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1626910.33448/rsd-v10i7.16269Research, Society and Development; Vol. 10 No. 7; e4110716269Research, Society and Development; Vol. 10 Núm. 7; e4110716269Research, Society and Development; v. 10 n. 7; e41107162692525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/16269/14511Copyright (c) 2021 Diogo Botelho Correa de Oliveira; Willames de Albuquerque Soares; Simone Rosa da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessOliveira, Diogo Botelho Correa deSoares, Willames de AlbuquerqueSilva, Simone Rosa da2021-07-18T21:07:03Zoai:ojs.pkp.sfu.ca:article/16269Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:52.032703Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
