The global popularity of green roofs (GRs) rises as urban runoff becomes a primary
environmental concern in both developed and developing countries. Although a growing …

Green roofs have the potential to offer numerous ecosystem services; however, they are
rarely designed to achieve them. Instead, design is restricted by perceived structural and …

This paper outlines the development of a conceptual hydrological flux model for the long
term continuous simulation of runoff and drought risk for green roof systems. A green roof's …

Conventional green roofs have often been criticised for their limited water buffer capacity
during extreme rainfall events and for their susceptibility to droughts when additional …

Evapotranspiration (ET) is a key parameter that influences the stormwater retention capacity,
and thus the hydrological performance, of green roofs. This paper investigates how the …

A four-year record of rainfall and runoff data from nine different extensive (80 mm substrate)
green roof test beds has been analysed to establish the extent to which the substrate …

Green roofs are widely considered as a promising nature-based solution for urban
stormwater management. In this study, the stormwater retention and detention performance …

This study aimed to evaluate the technical feasibility of a multilayer detention roof, namely a
purple roof, in managing urban stormwater. A purple roof is conceptually and technically …

Although it is widely accepted that the detention performance of green roofs is of interest to
stormwater engineers and planners, no single metric allows detention to be unambiguously …

Increasing recognition is being given to the adoption of green roofs in urban areas to
enhance the local ecosystem. Green roofs may bring several benefits to urban areas …
