Runoff quantity and quality from a 248 m2 extensive green roof and a control were compared in Connecticut using a paired watershed study. Weekly and individual rain storm samples of runoff and precipitation were analyzed for TKN, NO3 + NO2–N, NH3–N, TP, PO4–P, and total and dissolved Cu, Pb, Zn, Cd, Cr, and Hg. The green roof watershed retained 51.4% of precipitation during the study period based on area extrapolation. Overall, the green roof retained 34% more precipitation than predicted by… Expand

Design and Development of Low P-Emission Substrate for the Protection of Urban Water Bodies Collecting Green Roof Runoff
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,Expand
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 leachingExpand
Regulating urban surface runoff through nature‐based solutions – An assessment at the micro‐scale
TLDR
The study provides empirical support for the effectiveness of urban green infrastructure as nature‐based solution to stormwater regulation and assists planners and operators of sewage systems in selecting the most effective measures for implementation and estimation of their effects. Expand
Low Impact Development Practices: A Review of Current Research and Recommendations for Future Directions
Abstract A low impact development (LID) is an alternative land development approach for managing stormwater that has been recommended instead of the traditional stormwater design. The main purpose ofExpand
