SWMM file formats
The following SWMM file formats are supported by BlueM.Wave:
- SWMM5 binary output format (import)
- SWMM5 routing interface file (import/export)
- SWMM5 LID report file (import)
- SWMM5 time series file (import/export)
SWMM5 binary output format
SWMM5 binary output files have the file extension *.OUT. The file format is binary and described in the "SWMM API Guide" available here (Swmm5.2.4-ApiGuide.zip).
When a SWMM5 binary output file is opened with Wave, an import dialog is displayed, allowing the user to select the desired series for importing (see screenshot).
SWMM5 routing interface file
A routing interface file stores a time series of flows and pollutant concentrations that are discharged from the outfall nodes of drainage system model. This file can serve as the source of inflow to another drainage system model that is connected at the outfalls of the first system.

SWMM5 routing interface files are expected to have the file extension *.TXT by Wave.
BlueM.Wave detects a SWMM5 routing interface file by checking for the string SWMM5 at the beginning of the file.
Example (flow only):
SWMM5 Interface File RTC-Demonstrator , Regenbelastung Wupperverband , 60 - reporting time step in sec 1 - number of constituents as listed below: FLOW LPS 5 - number of nodes as listed below: S101 S201 S401 S203 S602 Node Year Mon Day Hr Min Sec FLOW S101 2001 6 10 0 0 0 0.000 S201 2001 6 10 0 0 0 0.000 S401 2001 6 10 0 0 0 0.000 S203 2001 6 10 0 0 0 0.000 S602 2001 6 10 0 0 0 0.000 S101 2001 6 10 0 1 0 1.960 S201 2001 6 10 0 1 0 0.420 S401 2001 6 10 0 1 0 1.400 S203 2001 6 10 0 1 0 0.560 S602 2001 6 10 0 1 0 4.900

SWMM5 LID report file
SWMM5 LID report files use the file extension *.TXT. They are recognized by BlueM.Wave by the text SWMM5 LID Report File in the first line.
Example:

SWMM5 time series format
Time series files are external text files that contain data for SWMM's time series objects. Examples of time series data include rainfall, evaporation, inflows to nodes of the drainage system, and water stage at outfall boundary nodes. The file must be created and edited outside of SWMM, using a text editor or spreadsheet program. A time series file can be linked to a specific time series object using SWMM's Time Series Editor.
- — Source: SWMM User's Manual Version 5.2, chapter 11.6[1]
This file format is expected to have the file extension *.DAT by Wave.
Wave supports the "date / time / value format", dates are expected to be in month/day/year format.
Example:
;Node S101 Total Inflow [LPS] 06/10/2001 12:01 12.960000038147 06/10/2001 12:02 12.960000038147 06/10/2001 12:03 12.960000038147 06/10/2001 12:04 12.960000038147 06/10/2001 12:05 12.960000038147 06/10/2001 12:06 12.960000038147 06/10/2001 12:07 12.960000038147
Notes
Currently not supported by Wave:
- Omission of repeating dates for timestamps of the same day
- The alternative "time / value format", where time can either be decimal hours or military time since the start of a simulation
