View source for TUFLOW CATCH Tutorial M03 Results QGIS

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

Refer to <u>[[TUFLOW_CATCH_Tutorial_M01_Results_QGIS | TUFLOW CATCH Tutorial 01]]</u> for information on timeseries outputs.

==Create JSON File==
Create a TUFLOW CATCH JSON file:
<ol>
<li> Go to Processing > Toolbox from the top drop down menu options to open the Processing Toolbox. 
<li> 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'''.
<li> Click 'Run'. Once the tool has finished, click 'Close'.
<li> 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.<br>

==TUFLOW CATCH Map Outputs==
Review the TUFLOW CATCH outputs using the JSON file:
<ol>
<li> In QGIS, open the 'Layer Styling' panel by hitting F7 or selecting View > Panels > Layer Styling Panel from the top drop down menu options. 
<li> In the Layer Styling panel, go to the 'Datasets' tab. There is a list of all available output types. Select 'Depth'.
<li> Go to the 'Contours' tab. Update the 'Depth' symbology as needed.
<li> In the Temporal Controller dock, use the time slider to view the depth results throughout the model simulation. <br>
<br>

<li> In the Datasets tab, select 'Velocity' - both the contours [[File: layer_styling_contours_01.png]] and the vectors [[File: layer_styling_vectors_01.png]]. 
<li> In the Vectors tab, set 'Arrow Length' to 'Scaled to Magnitude' and set the scale factor to 20. <br>
'''Note:''' The symbology has been adjusted similarly to the 'Depth' as shown above. 
<li> Use the time slider to observe the water flowing from the catchment area into the TUFLOW FV model domain. <br>

<li> Zoom into the eddies and use the time slider to observe the circular flow. <br>
