Resumo: Low impact development (LID) practices for urban drainage act to reduce the volume of surface runoff and amortize the flow discharged in conventional drainage systems. Despite the great environmental potential, the design of LID solutions still has gaps to be explored, especially when considering that the traditional way of sizing sources drainage systems takes into account only the intensity of the rain design. This paper presents an analysis of the influence of different design parameters on the sizing and performance behavior of the filling and emptying phases of dry-wells, aiming to define more unfavorable design situations. For this propose, different scenarios were studied considering different soil infiltration rates and project rainfall. It was observed that, for soils with infiltration rates below 1.10-5 m³/m²/s, the largest dry-well volume occurs when there is a long-term precipitation whereas for infiltration rates greater than 1.10-3 m³/m²/s, the largest volume results from a short duration and high intensity precipitation. Changing the diameter of the dry-well by 20% did not affect the emptying time considerably, however, the depth of the dry-well suffered changes of up to 43%.

A pesar del gran potencial ambiental, el diseño de técnicas de drenaje compensatorio aún tiene lagunas por explorar, especialmente si se considera que la forma tradicional de dimensionar estos sistemas de drenaje toma en cuenta solo la intensidad del diseño de la lluvia. Así, este trabajo presenta un análisis de la influencia de diferentes parámetros de diseño en el diseño y comportamiento de las fases de llenado y vaciado de pozos de infiltración de agua de lluvia, con el objetivo de definir situaciones de proyecto más desfavorables. Para ello, se estudiaron diferentes escenarios considerando diferentes tasas de infiltración del suelo y precipitaciones del proyecto. Se observó que, para suelos con tasas de infiltración inferiores a 1,10-5 m³/m²/s, el mayor volumen de pozo ocurre cuando hay una precipitación de largo plazo, mientras que para tasas de infiltración superiores a 1,10-3 m³/m²/s, de pozo resulta de una precipitación de corto plazo y alta intensidad. Cambiar el diámetro del pozo de infiltración en un 20% no afectó considerablemente el tiempo de vaciado, sin embargo, la profundidad del pozo sufrió cambios de hasta un 43%.As técnicas compensatórias de drenagem urbana atuam na redução do volume de escoamento superficial e no amortecimento da vazão de descarrega nos sistemas convencionais de drenagem. Apesar do grande potencial ambiental, a concepção destas técnicas ainda possui lacunas a serem exploradas, principalmente quando é considerado que a forma tradicional de dimensionamento dos sistemas de drenagem na fonte leva em consideração apenas a intensidade da chuva de projeto. Este trabalho apresenta uma análise da influência de diferentes parâmetros de projeto no dimensionamento e no comportamento das fases de enchimento e esvaziamento dos poços de infiltração de água de chuva visando definir situações mais desfavoráveis de projeto. Para tanto, foram estudados diferentes cenários de taxas de infiltração e chuvas de projeto. Observou-se que, para solos com taxas de infiltração abaixo de 1.10-5 m³/m²/s, o maior volume do poço ocorre quando se tem uma precipitação com longa duração, já para taxas de infiltração maior que 1.10-3 m³/m²/s, o maior volume resulta de uma precipitação de curta duração e alta intensidade. Alteração do diâmetro do poço de infiltração em 20% não afetou o tempo de esvaziamento de maneira considerável, contudo, a profundidade do poço sofreu alterações de até 43%.Programa de Pós-graduação em Arquitetura e Urbanismo, Faculdade de Arquitetura e Urbanismo2023-09-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo avaliado pelos paresapplication/pdfhttps://periodicos.unb.br/index.php/paranoa/article/view/4742110.18830/issn.1679-0944.n34.2023.17Paranoá; Vol. 16 No. 34 (2023): January/June Edition; 1-25Paranoá; v. 16 n. 34 (2023): Fluxo Contínuo - Janeiro/Junho; 1-251679-09441677-7395reponame:P@ranoáinstname:Universidade de Brasília (UnB)instacron:UNBporhttps://periodicos.unb.br/index.php/paranoa/article/view/47421/38483Copyright (c) 2023 Paranoáhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMundim, Victor de CastroReis, Ricardo Prado Abreu2024-02-08T15:00:47Zoai:ojs.pkp.sfu.ca:article/47421Revistahttps://periodicos.unb.br/index.php/paranoaPUBhttps://periodicos.unb.br/index.php/paranoa/oaiparanoa@unb.br1679-09441677-7395opendoar:2024-02-08T15:00:47P@ranoá - Universidade de Brasília (UnB)false
