Estudos de tecnologias em Sponge City para drenagem da água pluvial: aplicação no Rio Arrudas em BH

Abstract

Floods and floods in Brazilian urban centers reaffirm the problems between the relationship between the river and the city. The objective of the article is to establish the relationship between smart cities and their technologies for rainwater drainage, mitigating the problems resulting from an inefficient water system. The survey of these technologies in smart cities will help to understand the measures that are already applied and can be applied to mitigate events. The term "sponge city", is approached and developed in a Chinese city, where a system was created that replaces surfaces such as asphalt and concrete for surfaces with permeable soils, which absorb rainwater and work as a filter storing water for the whole city. With this, the work will seek to analyze the relationship between smart cities, and sponge cities, and the urban drainage system. The Arrudas stream on a stretch on Avenida Teresa Cristina in the Betânia neighborhood in the city of Belo Horizonte is the case study at work. In the area, a mapping of the site and a study are carried out for the possible implementation of measures and technologies for the intelligent absorption of rainwater. Keywords:
