Urbanization leads to higher phosphorus (P) concentration in urban catchments. Among different stormwater retention measures, green roofs are the least efficient in phosphorus retention. Moreover, much research has shown that green roofs act as sources of phosphorus, and they can emit P in significant loads. In this study low P emission green roof substrate was developed based on the proposed step by step procedure for the selection of materials including laboratory tests, column experiments…

Runoff and Water Quality in the Aspect of Environmental Impact Assessment of Experimental Area of Green Roofs in Lower Silesia
Green architecture, including green roofs, can limit the effects of urbanization. Green roofs soften the thermal effect in urban conditions, especially considering the significant increase in the
Phosphate Leaching from Green Roof Substrates—Can Green Roofs Pollute Urban Water Bodies?
Green roofs are an effective stormwater measure due to high water retention capacity and the ability of delaying stormwater runoff. However, low importance is still given to the pollutant leaching
The influence of a green roof drainage layer on retention capacity and leakage quality.
It can be concluded that the polypropylene mat and aggregates create different conditions for the formation of the leachate, in both volumes and its chemistry, which is the most effective in terms of rainwater retention capacity and the resultingLeachate quality.
Comparing the Retention of the Extensive Green Roofs with the Conventional Roof
The inevitable development of cities has necessitated of a searching for new alternative solutions that enable the retention of as much rainwater as possible and increase the biologically active
Phosphorus and Metals Leaching from Green Roof Substrates and Aggregates Used in Their Composition
Green roofs are constructions made of different layers, each serving a dedicated function. Substrates and materials used in their composition are essential from the point of view of rainwater
The influence of green roofs on runoff quality - 6 years of experience
Green roofs have gained global acceptance as a technology that is beneficial for both the environment and the urban population. It is generally believed that green roofs also improve the quality of
Impact of the Hydrogel Amendment and the Dry Period Duration on the Green Roof Retention Capacity
Abstract Climate changes as well as the urbanisation and economic development influence the characteristics of the stormwater runoff in the cities. The sealing of drainage basin surface leads to an
Combination of constructed wetland and extensive green roof that uses growing media with added recycled materials
This diploma thesis analyses in detail experimental concept of a constructed wetland-extensive green roof irrigated with pre-treated grey water. In a growing medium of the extensive green roof the
Role of Substrates Used for Green Roofs in Limiting Rainwater Runoff
The retention of rainwater is one of the main functions of green roofs in urban areas. One of the elements influencing the variability of rainwater retention on green roofs is the configuration of
Influence of environmental factors on retention of extensive green roofs with different substrate composition
Increasing recognition is being given to the adaption of green roofs in urban areas to enhance the local ecosystem. Green roofs may bring several benefits to urban areas including flood mitigation


The Role of Green Roofs as a Source/sink of Pollutants in Storm Water Outflows
Green roofs are increasingly used as sustainable urban drainage systems due to their retention and detention capacity; however, the impact of green roofs in term of water quality is still a debated
The Influence of Green Roofs on Runoff Water Quality: A Case Study from Estonia
