Since its inception, SWMM has been used in … Since its inception, SWMM has been used in thousands of sewer and stormwater studies throughout the world. Typical applications include:</br></br>* design and sizing of drainage system components for flood control</br>* sizing of detention facilities and their appurtenances for flood control and water quality protection</br>* flood plain mapping of natural channel systems (SWMM 5 is a FEMA-approved model for NFPI studies)</br>* designing control strategies for minimizing combined sewer overflows</br>* evaluating the impact of inflow and infiltration on sanitary sewer overflows</br>* generating non-point source pollutant loadings for waste load allocation studies</br>* evaluating the effectiveness of BMPs for reducing wet weather pollutant loadings.r reducing wet weather pollutant loadings. +
SWMM conceptualizes a drainage system as a … SWMM conceptualizes a drainage system as a series of water and material flows between several major environmental compartments. These compartments and the SWMM objects they contain include:</br></br>* The Atmosphere compartment, from which precipitation falls and pollutants are deposited onto the land surface compartment. SWMM uses Rain Gage objects to </br>represent rainfall inputs to the system.</br>* The Land Surface compartment, which is represented through one or more Subcatchment objects. It receives precipitation from the Atmospheric compartment in the form of rain or snow; it sends outflow in the form of infiltration to the Groundwater compartment and also as surface runoff and pollutant loadings to the Transport compartment. </br>* The Groundwater compartment receives infiltration from the Land Surface compartment and transfers a portion of this inflow to the Transport compartment. This compartment is modeled using Aquifer objects. </br>* The Transport compartment contains a network of conveyance elements (channels, pipes, pumps, and regulators) and storage/treatment units that transport water to outfalls or to treatment facilities. Inflows to this compartment can come from surface runoff, groundwater interflow, sanitary dry weather flow, or from user-defined hydrographs. The components of the Transport compartment are modeled with Node and Link objects.</br></br>Not all compartments need appear in a particular SWMM model. For example, one could model just the transport compartment, using pre-defined hydrographs as inputs., using pre-defined hydrographs as inputs. +
In addition to modeling the generation and … In addition to modeling the generation and transport of runoff flows, SWMM can also estimate the production of pollutant loads associated with this runoff. The following processes can be modeled for any number of user-defined water quality constituents:</br></br>* dry-weather pollutant buildup over different land uses</br>* pollutant washoff from specific land uses during storm events</br>* direct contribution of rainfall deposition</br>* reduction in dry-weather buildup due to street cleaning</br>* reduction in washoff load due to BMPs</br>* entry of dry weather sanitary flows and user-specified external inflows at any point in the drainage system</br>* routing of water quality constituents through the drainage system</br>* reduction in constituent concentration through treatment in storage units or by natural processes in pipes and channelsby natural processes in pipes and channels +

These include:</br>* time-varying rainfall</br>* evaporation of standing surface water</br>* snow accumulation and melting</br>* rainfall interception from depression storage</br>* infiltration of rainfall into unsaturated soil layers</br>* percolation of infiltrated water into groundwater layers</br>* interflow between groundwater and the drainage system</br>* nonlinear reservoir routing of overland flow.linear reservoir routing of overland flow. +
The EPA Storm Water Management Model (SWMM … The EPA Storm Water Management Model (SWMM) is a dynamic rainfall-runoff simulation model used for single event or long-term (continuous) simulation of runoff quantity and quality from primarily urban areas. The runoff component of SWMM operates on a collection of subcatchment areas that receive precipitation and generate runoff and pollutant loads. The routing portion of SWMM transports this runoff through a system of pipes, channels, storage/treatment devices, pumps, and regulators. SWMM tracks the quantity and quality of runoff generated within each subcatchment, and the flow rate, flow depth, and quality of water in each pipe and channel during a simulation period comprised of multiple time steps.n period comprised of multiple time steps. +
