Abstract: RESUMO O objetivo deste trabalho foi avaliar uma nova concepção de poço de infiltração como técnica de controle de drenagem pluvial na fonte. Esse poço, denominado P-GHidro, possui furos na parede dos anéis de concreto, camada de brita externa aos anéis para melhorar a distribuição de água, pré-filtro de geotêxtil na tampa e filtros adicionais no fundo e na lateral, entre a brita e o solo. Usou-se como referência o poço de infiltração comumente empregado em São Carlos, São Paulo (P-SC), cuja construção foi rea… Show more

“…They used values for infiltration rates from a double ring infiltrometer test. Ferreira, Barbassa and Moruzzi (2018) modelled two infiltration wells and they found mean R 2 of 0.92 and mean NS of 0.56. They performed a calibration similar to this study.…”

“…The average altitude is 860 m, and the relief is characterized by smooth hills. The soil was originated from the transport of the residuals from the Itaqueri Formation (sandstones, siltstones and claystones), and it is characterized by a thickness greater than 12 meters, a homogenous reddish yellow color and sandy clay texture (Figure 1) (Pejon, 1987;Failache & Zuquette, 2018), and by high infiltration rates with an average of 350 mm/h (Ferreira et al, 2018). The water table within a year varies between 9.8 and 12.0 m in relation to soil surface (Sírio, 2014).…”

“…O flw was determined by analyzing the drywell dimensions and the rainfall data for 2017 and 2018 years. The design rainfall was calculated by using the rain envelope method (Urbonas & Stahre, 1993) considering the PGHidro dimensions, the saturated hydraulic conductivity of 9.7 × 10 −5 m/s calibrated by Ferreira et al (2018), and the rainfall equation for São Carlos region (Barbassa, 1991). The maximum rainfall with 30 min duration for the 9-year return period was 29.6 mm, corresponding to an intensity of 59.2 mm/h.…”
