The Influence of Extensive Vegetated Roofs on Runoff Water Quality
Science of the Total Environment, 2006The influence of extensive sedum-moss vegetated roofs on runoff water quality was studied for four full scale installations located in southern Sweden. The aim of the study was to ascertain whether the vegetated roof behaves as a sink or a source of pollutants and whether the age of a vegetated roof influences runoff quality.

Roof Runoff Water Quality—A Comparison of Traditional Roofing Materials
World Environmental and Water Resources Congress 2010, 2010Increasing urbanization and rapidly growing populations are beginning to place a strain on the world's potable water supply. The use of harvested rainwater is one approach for freeing up potable water for more essential applications such as drinking water.

Time Focused Measurements of Roof Runoff Quality
Corrosion Science, 2008Abstract Runoff properties and their changes during runoff of a 14 year old zinc roof were investigated. Zinc, lead, cadmium, pH value, rain intensity and electric conductivity have been measured for a period of one year. A runoff rate of 3.73 g/m2 a and a volume weighted mean zinc concentration of 4.9 mg/L were determined.

The effects of a green roof on rainwater runoff
2011 International Conference on Consumer Electronics, Communications and Networks (CECNet), 2011To quantify the effects of a green roof on rainwater runoff physical experiments will be carried on. In the research, physical model which include rainfall generate, testing platform, observation system is established various confirmation of rainfall intensity and slope are examined. A major finding are that, a green roof has benefits of reducing flood

Roofing Materials Assessment: Investigation of Five Metals in Runoff from Roofing Materials
Water Environment Research, 2015ABSTRACT: To assess the contribution of five toxic metals from new roofing materials to stormwater, runoff was collected from 14 types of roofing materials and controls during 20 rain events and analyzed for metals. Many of the new roofing materials evaluated did not show elevated metals concentrations in the runoff.

Roof Runoff Control by Using the Green Blue Roof and Blue Roof in the Urban Area
Advanced Science and Technology Letters, 2016This study addresses the role of green (vegetated) blue roof and blue roof in the stomwater management in urban area. Green-blue roof and blue roof were constructed at two different location in Seoul, Korea. These two roofs can retain, delay the rainfall runoff and can also reduce the peak flow which are very helpful to avoid the flash flooding in ...

Wetland systems to control roof runoff
2006This chapter presents a case study that aims to optimize design, operation, and maintenance guidelines, and assesses the water treatment potential of a wetland system following 15 months of operation. A domestic property in Sandy Lane in Bradford, West Yorkshire, and England was selected for the pilot plant case study, where the surface water came from

Suspended Solids in and Turbidity of Runoff from Green Roofs
International Journal of Phytoremediation, 2011Green roof technology is used to reduce the quantity of stormwater runoff, but questions remain regarding its impact on quality. This study analyzed the total suspended solids (TSS) in and the turbidity of runoff from green roof growth media mixed with composted pine bark in an indoor pot study. The results showed that there were elevated levels of TSS

Bioavailability of zinc in runoff water from roofing materials
Chemosphere, 2002Corrosion and runoff from zinc-coated materials and outdoor structures is an important source for the dispersion of zinc in the environment. Being part of a large inter-disciplinary research project, this study presents the bioavailability of zinc in runoff water immediately after release from the surface of 15 different commercially available zinc ...
