Sumario: | 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.
