Definition of a SWMM Network¶

A SWMM network within MIKE+ can be defined in one of the following ways. Please note that MIKE+ supports the EPA SWMM5 format. If you have a SWMM44 model, conversion tools are available on the US EPA website.

Import of external data (e.g. GIS, *.inp, MIKE URBAN *.mdb or *.gdb) into MIKE+ SWMM network.
Copying network data from MIKE+ CS network into MIKE+ SWMM network
Graphical data digitalisation and manual data typing within MIKE+

Note

When importing existing model setups into MIKE+, ensure that Unit Systems and elevation reference settings are consistent.

The last option is frequently used in a combination with one of the previous options to build a well-defined SWMM network model.

The following paragraphs provide a comprehensive information on the SWMM network data model and the associated editors.

A SWMM network model consists of the following elements:

Nodes
