| 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 melting |
| · | rainfall interception from depression storage |
| · | infiltration of rainfall into unsaturated soil layers |
| · | percolation |
| 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 |
| · | Calibration Data Files |
| · | Time Series Files |
| · | Interface Files |

| 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 runoff. The design of the control is made on a per-unit-area basis so that it can be … Read the rest
| 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. The file is organized into sections, where each section generally corresponds to a particular category of object … Read the rest
| 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 can include the Study Area Map, a graph, a table, or a report.

| Control Rules |
Control Rules determine how pumps and regulators in the conveyance system will be adjusted over the course of a simulation. The use of control rules is explained in the following topics:
| · | Example Rules |
| · | Rule Format |
| · | Condition Clauses |
| · | Action Clauses |
| · | Modulated |
| 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 details. The Status Report will include an error statement, code, and description of the problem (e.g., ERROR … Read the rest
