Unit Hydrographs (UHs) estimate rainfall-dependent inflow/infiltration (RDII) into a sewer system. A UH set contains up to three such hydrographs, one for a short-term response, one for an intermediate-term response, and one for a long-term response. A UH group can have up to 12 UH sets, … Read the rest
| Introducing EPA SWMM5 |
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 … Read the rest
| Snowmelt |
Snowmelt parameters are climatic variables that apply across the entire study area when simulating snowfall and snowmelt. They include:
| · | the air temperature at which precipitation falls as snow |
| · | heat exchange properties of the snow surface |
| · | study area elevation, latitude, and longitude correction. |

The Tools Menu contains commands used to configure … Read the rest
| Working with Objects |
SWMM uses various types of objects to model a drainage area and its conveyance system. This section describes how these objects can be created, selected, edited, deleted, and repositioned.
… Read the restFlow routing within a conduit link in SWMM is governed by the conservation of mass and momentum equations for gradually varied, unsteady flow (i.e., the Saint Venant flow equations). The SWMM user has a choice on the level of sophistication … Read the rest
| Climatology |
The Climatology object in EPA SWMM describes the following climate-related variables used for computing runoff and snowmelt:
| · | Temperature |
| · | Evaporation |
| · | Wind Speed |
| · | Snowmelt |
| · | Areal Depletion |
| · | Climate Adjustments |
| Rain Gages |
Rain Gages supply precipitation data for one or more subcatchment areas … Read the rest
