SWMM5 Conversion Notes for SWMM Networks
This topic describes how InfoWorks ICM converts existing SWMM5 network components into ICM SWMM network objects, database items or model parameters. The description of each section that is imported from SWMM5 will indicate which network objects, database items or model parameters it is imported to.
The versions of EPA SWMM supported by the importer are v5.0 to 5.1.015
The importer supports the following:
