Abstract

 Fans are places with high permeability and have the highest share in recharge of aquifers. But with the development of urbanization and loss of permeable surfaces, occurs a lot of floods. In this study, quantitative and qualitative management of urban RUNOFF on the part of district 22 in Tehran is investigated. The research-based best management practices BMP, which is one of the most modern and effective methods of quantitative and qualitative urban RUNOFF is high. In these studies, EPA-SWMM software uses two strategies SWALE and Bio retention. System (green roofs) to control the flow and pollution, the concentration of total suspended solids (TSS) of the basin located in District 22 of Tehran Municipality was evaluated. The results showed an average decrease of 18.2% compared to the management solution of GREEN ROOF garden with an average reduction of climate 9.7 percent better performance in reducing the height of the peak RUNOFF is discharged from the basin. The results showed an average decrease of 18.2% compared with the GREEN ROOF management solution with an average reduction of 9.7 percent to SWALE, the better the height of the peak RUNOFF is discharged from the basin. The GREEN ROOF management solution on average 18.7% of the total pleasure of suspended solids (TSS) and SWALE decreased 12 percent. The GREEN ROOF more efficient management solution enjoys TSS removal. The GREEN ROOF is the best and most efficient management solution BMP was chosen for the study area.
