| Unit Hydrographs |
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 …
| 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. …
| 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 |
| Using Add-In Tools |
SWMM 5 has the ability to launch external applications from its graphical user interface that can extend its capabilities. This section describes how such tools can be …
| 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, …
| Flow Routing |
Flow 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 …
| Viewing Simulation Results |
This section describes the different ways in which the results of a simulation can be viewed. These include a status report, a summary report, various map views, …
| 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 |
| Aquifers |
Aquifers are sub-surface groundwater zones used to model the vertical movement of water infiltrating from the subcatchments that lie above them. They also permit the infiltration of groundwater into …
| Non-visual Objects |
In addition to physical objects that can be displayed visually on a map, SWMM utilizes several classes of non-visual data objects to describe additional characteristics and processes …
| Links |
Links are the conveyance components of a drainage system and always lie between a pair of nodes. Types of links include:
| · | Conduits |
| · | Pumps |
| · | Regulators |
| Conduits |
Conduits…
| Nodes |
Nodes are points of a conveyance system that connect conveyance links together. There are several different categories of nodes that can be employed:
| · | Junctions |
| · | Outfalls |
| · | Flow |
| Water Quality Modeling Features |
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 …
| Main Menu |
The Main Menu located across the top of the SWMM main window contains a collection of menus used for working with the program. These include:
| · |
| Hydrologic Modeling Features |
SWMM accounts for various hydrologic processes that produce runoff from urban areas. These include:
| · | time-varying rainfall |
| · | evaporation of standing surface water |
| · | snow accumulation and |
| Files Used by SWMM |
This section describes the various files that SWMM can utilize. They include:
| · | Project File |
| · | Report and Output Files |
| · | Rainfall Files |
| · | Climate File |
| LID Control Editor |
The LID Control Editor is used to define a low impact development control that can be deployed throughout a study area to store, infiltrate, and evaporate Subcatchment …
| Project File |
A SWMM Project File is a plain text file that contains all of the data used to describe a study area and the options used to analyze it. …
| Printing and Copying |
This section describes how to print, copy to the Windows clipboard, or copy to file the contents of the currently active window in the SWMM workspace. This …
| Troubleshooting Results |
When a run ends prematurely, the Run Status dialog will indicate that the run was unsuccessful and direct the user to the Status Report for …
