Vazão de projeto na microdrenagem em locais sem dados de precipitação: estudo para o Rio Grande do Sul

Abstract: Resumo O dimensionamento de estruturas da drenagem pluvial urbana é realizado, normalmente, a partir de dados de chuvas intensas. Essas informações comumente são obtidas por meio das relações intensidade-duração-frequência (IDF), ou na indisponibilidade destas, mediante metodologias simplificadas, tais como as relações entre durações, isozonas de chuvas, ou métodos sintéticos tais como os propostos por Bell (1969) e Chen (1983). Neste artigo é apresentada uma análise da aplicabilidade do método sugerido por Be… Show more

“…The terraces were built in the catchment that had a slightly higher average F I G U R E 1 Location of the region under study and monitoring units slope. The terraces were dimensioned based on the surface runoff volume calculated for a 110-mm rainfall event, considering a 10-year return period (RT), with a 6-h duration (Basso et al, 2019), and a 20 mm h À1 infiltration rate, which was obtained through the use of field survey data. Based on the measurements available, five mediumsized terraces with varying heights (40-70 cm) and a cross-sectional area (1.5-2.0 m 2 ) were built.…”
