Water retention efficiency of green roof systems
Flash floods in urban areas caused by overload of drainage networks are a recurrent problem with negative impacts of raising importance. Green roofs retain part of the storm water, lowering surface flow and generating runoff hydrographs with lower and delayed peak flows. Therefore, this technology c...

Flash floods in urban areas caused by overload of drainage networks are a recurrent problem with negative impacts of raising importance. Green roofs retain part of the storm water, lowering surface flow and generating runoff hydrographs with lower and delayed peak flows. Therefore, this technology can contribute to mitigate the overload of drainage networks. This communication presents the first results (partial) of the determination of the efficiency of water retention (indirectly from the drained water), in trial plots simulating green roofs, with two substrate depths and with two coverage situations (with and without vegetation). They show a positive trend of the green roof; in contributing to the reduction of runoff, with a greater retention in the vegetated plots and thicker substrate. |
