Article Synopsis
- Green roof systems (GRs) are useful for managing urban stormwater, but there is little long-term data on their effectiveness.
- This study analyzed 7 years of data from a 12-year-old GR in a Moist Subtropical Mid-Latitude Climate, showing it can retain 87% of annual precipitation and significantly reduce runoff and peak flow.
- The findings indicate that initial moisture levels affect GR performance, with potential improvements in evapotranspiration to enhance stormwater management effectiveness over time.
Evapotranspiration (ET) is an important water budget term for understanding the recovery of stormwater retention in green roof systems (GRs). However, ET evaluations, particularly in full-scale GRs, remain challenging. This study investigated ET dynamics within a GR in the City of Pittsburgh, USA, using a water balance based on continuously monitored soil moisture from moisture sensors over 15 months.
