==Introduction==
The updated culvert layers are supplied and inspected. 

== TUFLOW CATCH Project Re-Configuration ==
Re-configure the TUFLOW CATCH project to use and save empty files to the correct folders:
<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 Project'. This opens the dialog shown below.
* Project Name: '''TC03'''
* Project Folder: Click '...', and navigate to the '''TUFLOW_CATCH_Module_03\Modelling''' folder.
* Project CRS: Click the drop down menu and select 'Project CRS: EPSG:32760 - WGS 84 / UTM zone 60S’.
* TUFLOW HPC Executable: Click '...', and navigate to the '''exe\TUFLOW\2026.0.0''' folder. Select '''TUFLOW_iSP_w64.exe'''.
* TUFLOW FV Executable: Click '...', and navigate to the '''exe\TUFLOWFV\2026.0.0''' folder. Select '''TUFLOWFV.exe'''.
* Default GIS Format: Click the drop down menu and select 'SHP'.
* Tick on 'Create Empty Files'.
<li> Click 'Run' and a console window will open. This creates the empty GIS files.
<li> Once the tool has finished, click 'Close'.<br>

<br>
<li> Set up the QGIS workspace by setting the projection to EPSG:32760, loading and styling the DEM and saving the workspace. See <u>[[TUFLOW_CATCH_Tutorial_M01_Project_Initialisation_QGIS | TUFLOW CATCH Module 01 - Project Initialisation]]</u> for details.
</ol>

==Review Supplied TUFLOW Input Files==
Navigate to the '''TUFLOW_CATCH_Module_03\Tutorial_Data''' folder. Copy the below layers into the '''Modelling\TUFLOW\model\gis''' folder:
:* '''1d_nwk_TC03_001_L'''
:* '''2d_bc_TC03_001_L'''
:* '''2d_bc_TC03_001_P'''

For this tutorial, a TUFLOW FV mesh will be included in the channel (outlined in the next section: <u>[[TUFLOW_CATCH_Tutorial_M03_TUFLOW_FV_GIS_Inputs_QGIS | TUFLOW FV GIS Inputs]]</u>). Currently, there is a TUFLOW HPC culvert defined in the channel. This culvert needs to be removed from the TUFLOW HPC, and redefined in TUFLOW FV format. 
<ol>
<li>Load the supplied files into QGIS and use the 'Apply TUFLOW Styles to Open Layers'.
<li>Notice that the downstream culvert has been removed. All other culverts are the same.<br>
