论文摘要:A study was carried on the effectiveness of green roofs to abate Storm water using computer simulation。 In this study, the storm water performance was simulated for a modular block green roof using a packaged soil moisture simulation, HYDRUS-1D, with simulation results verified by study site data。 Simulations were run using HYDRUS-1D for 24-h design storms to determine peak flow, retention and detention time for runoff。 Storm data collected as part of a green roof study were used to validate HYDRUS-simulated runoff。 The study site consisted of a 37 m2 (400 ft2) modular block green roof containing engineered soil and vegetation including several Sedum species。 The study revealed that rainfall depth per storm strongly influences the performance of green roofs for storm water abatement, providing complete retention of small storms (
