Simulation and feasibility of biological and structural BMPs for stormwater control in the urbanizing watersheds

摘要: The development and increasing of construction activities results in the permeability reduction surfaces consequently improper impacts on transport convey surface runoff urban areas. Regarding areas, it is crucial to select implement best management practices (BMPs), functional practical methods for reducing controlling volume. In this research, BMPs are implemented one developing areas Tehran, Iran, with 30 sub-watersheds modeled stormwater model program. Then, effects implementing investigated volume main manholes collecting transporting network. For purpose, plan maps prepared different hydrological conditions, regarding their types implementation Besides, design, maintenance BMPS evaluated economically. According obtained reduced 33–70 22–54%, respectively, low high intensity rainfalls return periods 2–10 years. These can provide a strategic approach properly understanding Moreover, they be considered as an important step promote
