CAN GREEN ROOFS PURIFY STORMWATER RUNOFF? - THE ESTABLISHMENT OF EXPERIMENTAL GREEN ROOFS

This article introduces the establishment of the experimental green roofs and of green roof research on Mendel University in Brno. The experimental green roofs were established in August 2015 and it is based on current issues of rainwater management and the quality of storm water launched into recipients or sewage system. There is a valid legislation addressing the management of rainwater in environment - decree no. 268/2009, Coll., and decree no. 269/2009, Coll. Four experimental plots were created and placed in Mendel University Campus. It was hypothesized that different types of experimental plots will result in different amount of retained water and in different quality of water runoff. Water quality will be monitored and evaluated by Government Regulation no. 23/2011, Coll., using spectrophotometric method, then analysed in laboratory of the Department of Applied and Landscape Ecology, Mendel University in Brno.
