Due to the complexities of the urban environment, in recent years flood risk in urban basins in comparison with non-urban basins has increased. Flooding in urban areas, causes damage to buildings and other large urban infrastructure and it slow down or completely hinder traffic system. In this paper, urban flood management to reduce flooding low-impact development techniques, using methods such as porous pavement and infiltration trenches are discussed. For this purpose, using the software EPA-SWMM, in an area of Tabriz municipality, a network of surface water collecting was assessed and with four events at the time of simulation model, it was validated and calibrated. The network collects surface water in the three scenarios underlying the adoption of the final version of the LID by hydraulic capacity of streams and reducing peak flood runoff was investigated. The results showed that the majority of the urban network in flood return periods of 2, 5 and 10 years old, storm water drainage do not have the necessary capacity and respectively 28, 45 and 48 percent of the network will be flooded in critical situations. Well as the LID trenches influence over Porous Pavements for return periods of 2, 5 and 10 years old, in the same condition in about 8 to 10 percent better performance in reducing peak runoff from watersheds and reduce flood risk while increasing groundwater is an important breakthrough as the best and most efficient way of management (BMP) for the study area were identified.
