Green roof's impacts 4
Green roof is very efficient for current rainfall events in terms of peak discharge and runoff volume reduction
Simulation results obtained for 22/07/2011 event: Qsim-Imp corresponds to the current situation (without any green roof) and Qsim-IS=50%, Qsim-IS=30% and Qsim-IS=10% to green roof situations characterized by an initial saturation of the substrate of about 10, 30 and 50%
