Green Roofs Water Management

They provide a way for roofs to be converted into pervious areas and used beneficially rather than contributing to storm water management problems palla et al 2009 the overall aim of this chapter is to analyze and discuss the interactions.

Green roofs water management.

Stormwater management is the. Green roofs can be effective in both urban and rural areas as a solution to managing rainwater drainage. Stormwater management is a growing concern for numerous municipalities especially given the increase in flooding events. Somewhere between 40 and 80 percent of the total volume of rain that falls on green roofs can be retained.

The plants and growing medium of a green roof absorb water that would otherwise become runoff and research indicates that peak flow rates are reduced by 50 percent to 90 percent compared to conventional roofs. Up to 75 of rainfall is absorbed by an extensive living roof and up to 90 is absorbed by an intensive green roof system. Green roofs are determinant for the hydrologic restoration in urban areas and an interesting alternative to more conventional practices. Green roofs the key hydrological mechanism for interception storage and filtration of water.

Green roofs sequester rain and carbon pollution as well. Green roofs can remove carbon dioxide and produce oxygen. Moreover the water that is. The use of any technique or approach that reduces the rate and volume of rainwater runoff has the potential to contribute to better management of the overall quality of rainwater one approach that is used more and more frequently in the management of rainwater i e.
