Introduction

Use the TUFLOW CATCH plugin to create a TUFLOW CATCH JSON file to review the TUFLOW HPC and TUFLOW FV results simultaneously.

Refer to TUFLOW CATCH Tutorial 1 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 page? '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 TC02_001_catchment_hydraulic.xmdf and TC02_001_receiving_HD.nc (hold Ctrl to select multiple).
    • Output File: Click '...', and navigate to the TUFLOWCatch\results folder. Save the output file as TC02_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 and drag and drop TC02_001.tuflow.json into QGIS.
  5. This will open up a 'Temporal Controller' dock. Hit F7, to open the 'Layer Styling' panel. The Temporal Controller dock and the Layer Styling panel will be used to review the simulation outputs.


TUFLOW CATCH Map Outputs

Review the TUFLOW CATCH outputs using the JSON file:

  1. In the Layer Styling panel, go to the 'Datasets' tab. There is a list of all available output types. Select 'Depth'.
  2. Go to the 'Contours' tab. Update the 'Depth' symbology as needed.
  3. In the Temporal Controller dock, use the time slider to view the depth results throughout the model simulation.


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