The wetland as an element of the roof garden

Abstract

"Wetlands are among the most productive ecosystems that retain water, protect against floods, support biodiversity, purify water, retain nutrients, and stabilize local climate conditions. Based on the advantages of natural wetlands, constructed wetlands are created and often used for grey water treatment, called eco-purifiers or root purifiers. Because of the need to use the land space for other purposes, the idea of placing a wetland on the roof has been considered. The paper presents the wetland roof as a special variant of the green roof. It focuses on three wetland roofs that were created as part of the greenIZOLA project in Slovakia over the last two years. Moreover, it summarizes the knowledge gained from the operation of the wetland roof in the climatic zone of Slovakia."
