Feasibility study of runoff collected in Tehran's Highways

Today, control and collect runoff within the metropolitan area to transfer it out of town is more important. Region 1&3 in North East of Tehran that have area of 272 km2, when large amounts of rainfall runoff the stream in the streets make also several problems. This study using topographic maps of 1: 25,000 Tehran, geological map 1: 100000 Tehran, user data, and data from satellite aster pixels 30 meters, the rainfall hourly data’s station northern Tehran in the period 2007 to 2014, the feasibility collect and control runoff has done. The potential’s production runoff compute with Justin in regions 1&3. Modarres highway and Saryati Street locate biological systems and atmospheric garden, were selected. Locating action along these two street using LID and to assess and correct it reports flooded after the rain, in the center of Tehran Municipality were 137. Calculation of longitudinal profiles were SWMM software. Compare the results calculated daily runoff, topography and streams, showed that during the rainy, the part of runoff produced, drainage to the streets and highways. The best of locating control and collect runoff systems are green space in the aboatash, melat and gheytariyeh parks.
