Abstract

Storm water is among the major source of the urban flash floods problem. Roof surfaces account for a large portion of impervious surface in urban area as well pavement surfaces such as road. Establishing roof with vegetation or green roof or vegetated roof can help to mitigating storm water runoff equivalent to the control at point sources . The aim of this study was to obtain the effectiveness of the vegetated roof in reducing the quantity of storm water runoff. Two models offlat type roof were built in a small scale, one vegetated roof (test) and one nonvegetated roof (control). Flow rate and retention capacity were investigated for both models. The results showed that the vegetated roof model retained 17 % to 48 % storm water runoff from rainfall. Overall, vegetated roof may become an alternative in urban storm water management particularly but with proper design and planning to achieve the benefit efficiently.
