EXAMPLE DATA SETS======================================================
Several example data sets have been included with this package. They are placed in a sub-folder named EPA SWMM Projects\Examples in your My Documents folder. Each example consists of a .INP file that holds the model data and a .TXT file with suggestions on running it.
* EXAMPLE1.INP models runoff quantity and quality from a small watershed and its routing through a network of storm sewers. It can be run in either single event mode or in continuous mode using the companion rainfall file.
* EXAMPLE2.INP is Example 1 of the 1988 EXTRAN Users Manual. It illustrates how SWMM 5 can graphically compare its results to observed data stored in a text file.
* EXAMPLE3.INP illustrates the use of the rule- based controls feature in SWMM 5 for simulating real-time control.
* EXAMPLE4.INP shows how the LID controls feature in SWMM 5 was used to reduce runoff produced from a 29 acre mixed development site.
