摘要: The urbanization process brings modification in the urban water cycle, causing floods. The green roofs are being seen, together with other kinds of green infrastructure, as essential to improve resilience and sustainability in cities. Despite its advantages, the performance concerning hydrological effects, vegetation importance and maintenance requirements are still uncertain notably in tropical climate conditions, where the number of consecutive dry days are important. The present work aims to present the results of hydrological monitoring during a rainy season of three extensive green roofs under tropical conditions, in Belo Horizonte, Brazil. The green roofs differ from each other in vegetation, one was planted with grass, the second one has Sedum plants and the third one was not vegetated. The rain events are still in analysis, but preliminary results show that the runoff reduction is important and the runoff delay …
