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, TC03_001_receiving_HD.nc and TC03_001_receiving_WQ.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'.
   
   
   

TUFLOW CATCH Map Outputs

Review the TUFLOW CATCH outputs using the JSON file:

1. In Windows File Explorer, navigate to the TUFLOWCATCH\results folder and drag and drop TC03_001.tuflow.json into QGIS. Hit F7 to open the Layer Styling panel.
2. In the Layer Styling panel, select 'Conc SED_CLAY' as the result type. Update the symbology as needed.
3. In the Temporal Controller dock, use the time slider to view the pollutant transferring from the catchment (TUFLOW HPC) into the receiving waters (TUFLOW FV). This connection is particularly clear through the western upstream culvert.
   
   
   
4. will have a couple examples of the transfer in the video, but should I mention anything else ?
