Impact of roof surface runoff on urban water quality [PDF]

Water Science and Technology, 2012
The pollutant impacts of urban stormwater runoff on receiving waters are well documented in research literature. However, it is road surfaces that are commonly identified as the significant pollutant source. This paper presents the outcomes of an extensive program of research into the role of roof surfaces in urban water quality with particular focus ...

Analysis of Rainwater and Runoff Water Quality on Vegetated and Unvegetated Green Roof [PDF]

BIO Web of Conferences
Green roof is a green technology innovation in the form of a roof planted with vegetation on a substrate that is an effective solution to replace the role of green open space (GOS) lost due to construction and development.

Runoff detention effect of a sedum green-roof [PDF]

Hydrology Research, 2007
In order to estimate the detention effect (storage and peak flow attenuation) of a sedum green-roof, a comparison between the response of an impervious roof (runoff coefficient C=1) and a green-roof has been carried out. Precipitation and runoff data from several controlled experiments (with wet initial conditions, i.e. approximately at field capacity)

Qualitative aspects of roof runoff

, 1995
Runoff water from three different roofs (a tile, a polyester, and a gravel roof) was analysed. Rain water and dry depositions were also considered. Chemical analysis included general parameters, major ionic compounds, heavy metals and organic compounds (triazines).

Roof runoff quality and reduction possibility of the pollutants

Pollack Periodica, 2011
The analyzed samples were runoff waters from bituminous roofing. The runoff water pH was lower than that of the storm-water. First flush phenomena were observable in the samples conductivity, turbidity as well as suspended solid, dry and organic matter concentration.

An analysis on the efficiency of green roof in managing urban stormwater runoff [PDF]

, 2021
Modernization has created new impervious urban landscape contributed to major catastrophe. Urban drainage system incapable to convey the excess rainwater resulting in flash flood due to heavy rainfall.

Probabilistic estimation of runoff from green roofs

International Journal of Computational Methods and Experimental Measurements, 2022
In recent decades, green roofs are encouraged as effective tools of sustainable urban drainage system for stormwater management. They contribute to the reduction of runoff peak flows and volume discharges to sewer systems. Green roof reliability in stormwater control is mainly a function of storage capacity, given by the growing medium and the drainage

Performance of a zeolite filter treating copper roof runoff [PDF]

Urban Water Journal, 2022
Copper is a common roofing material used in urban environments, yet it poses a threat to the ecosystem. Space requirements for stormwater treatment in urban areas are often problematic. This study investigated the treatment efficiency of a filter system containing zeolite as filter medium and treatment of copper roof runoff in field conditions ...

Comparing the hydrological performance of an irrigated native vegetation green roof with a conventional Sedum spp. green roof in New York City.

PLoS ONE, 2022
The objective of this study was to compare the hydrological performance of an irrigated, 127 mm deep green roof, planted with vegetation native to the New York City area, to a conventional, non-irrigated, 100 mm deep green roof, planted with drought ...

Review on inorganic pollutants in stormwater runoff of non-metal roofs

Frontiers in Environmental Chemistry, 2022
Metal roofs have always been in the focus of stormwater runoff contamination. However, other roofing materials are also suspected of releasing metals and other inorganic substances with stormwater runoff.
