Trincheira de infiltração como técnica compensatória no manejo das águas pluviais urbanas

Abstract: Resumo Este trabalho apresenta um projeto experimental de uma trincheira de infiltração instalada na cidade de Recife, PE, nos primeiros meses de vida útil. Foram avaliadas as funções de armazenamento de água no interior do sistema e a função de infiltração, observando-se o processo de recessão. Em razão dos consequentes eventos de precipitação, a trincheira foi muito solicitada, não tendo suprido, em alguns casos, o grande volume de entrada, o que gerou extravasamento na estrutura. Uma análise de custo foi im… Show more

“…The structure sizing was performed by envelope curves, which is a method that uses the maximum water height to determine the storage volume. A return period (Tr) of 5 years was considered and inserted in the precipitation equation developed for the city of Recife [4].…”

“…Other hydrological consequences of waterproofing encompass increased runoff volume and velocity (i.e., flood risk). Thus, rainwater infiltration and retention techniques, such as rain gardens [2,3], infiltration trenches [4], infiltration basins [5,6] and permeable pavements [7][8][9] have emerged as means of reducing effective precipitation and assisting in water source control [10]. These alternative techniques include the comprehension of adverse urbanization effects, aiming to act on the causes of hydrological impacts.…”

“…As trincheiras de infiltração são áreas escavadas preenchidas por material granular do tipo brita ou seixos rolados, proporcionando uma infiltração direcionada das águas superficiais no solo (Melo et al 2016). São projetadas ao longo de superfícies impermeáveis cujo comprimento linear é superior às suas largura e profundidade.…”

“…These techniques, also called compensatory techniques, consist of bioretention cells, infiltration trenches, infiltration ditches, permeable pavements, green roofs, rain gardens, water catchment systems, and others (Eckart et al, 2017). Several studies have confirmed the quantitative and qualitative benefits of LIDs in the hydrological cycle (Coutinho et al, 2015(Coutinho et al, , 2016Melo et al, 2016). Permeable pavements are remarkably effective in terms of runoff reduction, retention and water quality (Kamali et al, 2017;Braswell et al, 2018).…”
