Table comparing and contrasting the features of the Storm Water Management Model (SWMM5) and the EPANET Water Distribution System (WDS)
| Feature | SWMM5 | EPANET |
|---|---|---|
| Subcatchments | Subcatchments represent the land area that contributes runoff to a stormwater system. They can be specified by size, slope, and land use. | Junctions represent the points where pipes connect in a distribution system. They can be specified by demand and elevation. |
| Links | Links model the flow of water through a stormwater system. They can be specified by size, material, and roughness coefficient. | Pipes model the flow of water through a distribution system. They can be specified by size, material, and roughness coefficient. |
| Junctions | Junctions model the points where links connect in a stormwater system. They can be specified by elevation and initial water depth. | Junctions model the points where pipes connect in a distribution system. They can be specified by demand and elevation. |
| Outfalls | Outfalls model the points where water leaves a stormwater system, such as a stream or river. They can be specified by type and discharge coefficient. | Valves are used to control the flow of water in a distribution system. They can be specified by type and setting. |
| Storage | Storage models the volume of water that can be stored in a stormwater system. It can be specified by size, shape, and initial water depth. | Reservoirs and tanks are used to model water storage in a distribution system. They can be specified by size and initial water level. |
| Infiltration | Infiltration models the infiltration of water into the ground, |
