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 rest
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 equations). The SWMM user has a choice on the level of sophistication … Read the rest
| 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, graphs, tables, and a statistical frequency report.
| 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
| 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 the drainage system, or exfiltration of surface water from the drainage system, depending on the hydraulic gradient … Read the rest
| 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 within a study area.

| 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 are pipes or channels that move water from one node to another in the conveyance system. Their … Read the rest
| 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 Dividers |
| · | Storage Units |
Nodes are also the points where external inflows can enter a drainage system … Read the rest
| 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 following processes can be modeled for any number of user-defined water quality constituents:
