EPA/600/R-09/077

The EPA Storm Water Management Model (SWMM) is a dynamic rainfall-runoff simulation model that computes runoff quantity and quality from primarily urban areas. This manual is a practical application guide for new SWMM users who have already had some previous training in hydrology and hydraulics. It contains nine worked-out examples that illustrate how SWMM can be used to model some of the most common types of stormwater management and design problems encountered in practice. These include: computing runoff for both pre- and post development conditions; analyzing the hydraulics of simple collection systems; designing a multi-purpose detention pond; modeling distributed low impact runoff controls; simulating the buildup, washoff, transport and treatment of stormwater pollutants; analyzing both dual drainage and combined sewer systems; and running long-term continuous simulations. Each example is accompanied by a complete SWMM input data file.
