Introduction

Create a TUFLOW CATCH JSON file and use it to view the transfer from TUFLOW HPC to TUFLOW FV.

Refer to TUFLOW CATCH Tutorial 01 for information on timeseries outputs.

Create JSON File

Create a TUFLOW CATCH JSON file:

  1. Go to Processing > Toolbox from the top drop down menu options to open the Processing Toolbox.
  2. Go to TUFLOW Catch in the processing tool list and select 'Create TUFLOW Catch JSON'. This opens the dialog shown below.
    • Results: Click '...', and select 'Add File(s)...'. Navigate to the TUFLOWCATCH\results folder and select TC03_001_catchment_hydraulic.xmdf and TC03_001_receiving_HD.nc (hold Ctrl to select multiple).
    • Output File: Click '...', and navigate to the TUFLOWCATCH\results folder. Save the output file as TC03_001.tuflow.json.
    • res_to_res.exe: Click '...', and navigate to the TUFLOW_CATCH_Tutorial_Models\exe\res_to_res.2024-02-AA folder. Select res_to_res_w64.exe.
  3. Click 'Run'. Once the tool has finished, click 'Close'.
  4. In Windows File Explorer, navigate to the TUFLOWCATCH\results folder. Drag and drop TC03_001.tuflow.json into QGIS. The 'Temporal Controller' panel will open automatically.


TUFLOW CATCH Map Outputs

Review the TUFLOW CATCH outputs using the JSON file:

  1. In QGIS, open the 'Layer Styling' panel by hitting F7 or selecting View > Panels > Layer Styling Panel from the top drop down menu options.
  2. In the Layer Styling panel, go to the 'Datasets' tab. There is a list of all available output types. Select 'Depth'.
  3. Go to the 'Contours' tab. Update the 'Depth' symbology as needed.
  4. In the Temporal Controller dock, use the time slider to view the depth results throughout the model simulation.


  5. In the Datasets tab, select 'Velocity' - both the contours File:Image of contour button and the vectors File:Image of vector button.
  6. In the Vectors tab, set 'Arrow Length' to 'Scaled to Magnitude'.
  7. Use the time slider to observe the water flowing from the catchment area into the TUFLOW FV model domain.
  8. show water flowing through culvert??
