SWMM Check Files

Text Data

When TUFLOW runs SWMM, it can accommodate for multiple INP input files within the SWMM Control file. TUFLOW combines the input INP files into a single combined INP file for the simulation execution. The combined file TUFLOW uses is written to the TUFLOW\results folder.

  1. Open TS02_5m_001_swmm.inp from TUFLOW\results in a text editor (for example Notepad++).
  2. Review the Junction, Outfall, Conduit, Losses, and XSections information.

QGIS Data

The QGIS TUFLOW Plugin SWMM Processing Tool, 'GeoPackage - Create from SWMM inp' can be used to create a spatial GeoPackage version of the INP data for post simulation review checking.

  1. In the Processing Toolbox, select 'GeoPackage - Create from SWMM inp'. This opens the dialog shown below.
    • SWMM Input File (inp): Navigate to the TUFLOW\results folder and select TS02_5m_001_swmm.inp.
    • CRS for GeoPackage: Click the drop down menu and select ‘Project CRS: EPSG:32760 - WGS 84 / UTM zone 60S’.
    • SWMM Tags to ignore: leave blank.
    • GeoPackage output filename: Click the ... and select 'Save to GeoPackage'. Navigate to the TUFLOW\check folder and set the GeoPackage output filename to TS02_5m_001_swmm_check.gpkg.
  2. Click 'Run'.
  3. Once the tool has finished, click 'Close'.
  4. TS02_5m_001_swmm_check.gpkg will now be available in the TUFLOW\check folder.
  5. In File Explorer, navigate to the TUFLOW\check folder and drag and drop TS02_5m_001_swmm_check.gpkg into QGIS.
  6. When prompted by QGIS, select 'Add Layers to open all layers within TS02_5m_001_swmm_check.gpkg. By default, all items in the available list should have been selected.
  7. Review the Junction, Outfall, Conduit, Losses, and XSections information.

Load TUFLOW Check Files

  1. In File Explorer, navigate to the TUFLOW\check folder and drag and drop TS02_5m_001_Check.gpkg into QGIS.
  2. When prompted by QGIS, select TS02_5m_001_swmm_pit_P and TS02_5m_001_1d_to_2d_check_R (hold Ctrl to select multiple), then click 'Add Layers'.
  3. Use the 'Apply TUFLOW Styles to Open Layers'.
  4. Also open, TS02_5m_001_DEM_Z from TUFLOW\check. Style the topography check file using the same hillshade styling you used for the input DEM model geometry.
