Abstarct: Urban development, land use change and industrialization of the communities cause hydrological changes in the catchment area, and this factor causes an increase in the amount of runoff in the area, erosion and destruction of the ecosystem health of the region. Low impact development (LID) In the dominant, Best Management Practices(BMP) is a relatively new concept in land use management that aims to maintain hydrological conditions at a predevelopment level without deteriorating water quality during land development. therefor BMP options have been proposed as an alternative approach to better mimic the natural flow regime by using decentralized designs to control stormwater runoff at the source, rather than at a centralized location in the watershed. For highly urbanized areas, BMP stormwater management practices can be used to retrofit existing infrastructure and reduce runoff volumes and peak flows. The United States Environmental Protection Agency (USEPA) developed the Storm Water Management Model (SWMM) to evaluate the performance of LID practices at different spatial scales. In this study the existing hydrological model was applied to neyshabour watershed. Model Calibration and validation with used measured 9 rainfall (6 for calibration and 3 for validation) were performed, Then the seven BMPs scenario such as Bioretension, Bioretention Systems, infiltration Trench, Permeable Pavment, Rain Barrel, RainGarden and BMP Integration were designed baxsed on the land characteristics were selected to estimate the impacts of BMPs and LID practices on the surface runoff. Results demonstrated that use of these BMP-LID practices leads 45.87% reduction in runoff volume in Scenario 7 (BMPs integration). Among the other scenarios, the scenarios 3, 4 and 1, respectively, have the highest efficiency in reducing runoff volume, respectively In order to achieve the optimal combination of BMPs, four other scenarios were chosen: the results showed that the barrel of the rain had 0.3% impact has of the least volume reduction.
