Abstract
Low-impact development (LID) is an important infrastructure method for improving urban drainage through stormwater best management practices. The parameterisation sensitivities for LID techniques are provided for the current Environmental Protection Agency (EPA) Stormwater Management Model (SWMM). This was completed with the measured LID quantity data from over a 10-year data sample that included pervious pavements and infiltration swales in a commercial area. Critical parameter sensitivities were analysed using the recently released EPA SWMM version 5.1.011. Computational results provide SWMM users a range of acceptable parameter values to simulate these best management practices, to design future LIDs, and other urban green areas to reduce stormwater run-off impacts. This analysis demonstrated sensitivity relationships of key parameters allowing engineers, designers and planners to simulate sustainable urban infrastructure at other locations.
