Another important benefit of green roofs is their ability to reduce and slow stormwater runoff in urban environments.

Green roof runoff impact.

Green roofs can retain nearly all storm related precipitation during the summer months with lower retention during the winter months 20. Green roofs can reduce and slow stormwater runoff in the urban environment and also filter pollutants from rainfall. Green roof runoff does contain concentrations of some nutrients and other parameters but values are in line with other planted systems. A portion of the captured rainfall evaporates or is taken up by plants which helps reduce runoff volumes peak runoff rates and pollutant loads on development sites.

Due to the volume reduction actual nutrient loadings from green roofs are less than asphalt roofing runoff or otherwise manageable at the downspout. The stormwater management benefit provided by green roofs lies in the ability of the soil media and plants to retain stormwater increase evapotranspiration and allow stormwater runoff to be released gradually to receiving waters at decreased flow rates. With a green roof however the setup for routing the event is more complex. Enhanced stormwater management and water quality.

In summer a green roof can typically retain between 70 80 of the runoff. Green roofs are stormwater management practices that capture and store rainfall in an engineered growing media that is designed to support plant growth. In summer a green roof can typically retain between 70 80 of the runoff green roofs can help to reduce the surface run off entering the drainage system. Due to the volume reduction actual nutrient loadings from.

The current paper has focused on the analysis of the impact of green roof construction on stormwater production. Green roof facilities act as a reduction of impervious surfaces where the largest or almost integrally the rainfall volumes produces runoff flowing into the urban drainage system. Factors which affect influence of a green roof on runoff water quality are discussed in general terms followed by the review of data regarding concentrations of phosphorus nitrogen and heavy metals in green roof runoff its ph and first flush effect.
