== Introduction ==
QGIS is used to configure the TUFLOW CATCH project with the TUFLOW CATCH plugin. For installation, see <u>[[TUFLOW_CATCH_QGIS_PluginTUFLOW_CATCH_Tutorial_Introduction#Software_Requirements | TUFLOW CATCH QGISTutorial PluginIntroduction]]</u>.
 
There are three steps to set up the TUFLOW CATCH project:
Line 19:
<li>Ensure that the projection is set correctly by viewing the bottom right hand corner of the workspace. It should read ‘EPSG:32760’.

Line 25:
Create the TUFLOW CATCH project:
<ol>
<li> Go to Processing > Toolbox from the top drop down menu optionoptions to open the Processing Toolbox.
<li> Go to TUFLOW Catch in the processing tool list and select <font color=red>create page?</font> 'Create TUFLOW Catch Project'. This opens the dialog shown below.
:*Project Name: '''TC01'''
:*Project Folder: Click '...', and navigate to the '''TUFLOW_CATCH_Module_01\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\2025.01.20''' folder. Select '''TUFLOW_iSP_w64.exe'''.
:*TUFLOW FV Executable: Click '...', and navigate to the '''exe\TUFLOWFV\2025.01.0''' folder. Select '''TUFLOWFV.exe'''.
:*Default GIS Format: Click the drop down menu and select 'SHP'.
:*Tick on 'Create Empty Files', 'Create Folder Structure' and 'Setup Control File Templates'
:*<font color=red>?</font>Control File Templates: Expand the 'Advanced Parameters' section. Click '...', and tick on: TUFLOW CATCH Control file (.tcc), Batch file (.bat) and ESTRY Control file (.ecf). Ensure all other files are ticked off.
 
<li> Click 'Run' and a DOS console window will open. This creates the TUFLOW CATCH folder structure, the projection files, the empty GIS files and template control files.
<li> Once the tool has finished, click 'Close'.<br>

The TUFLOW CATCH folder structure will now be set up in the '''TUFLOW_CATCH_Module_01\Modelling''' folder. The template files '''TC01_001.tcc''', '''Demonstration.bat''' and '''TC01_001.ecf''' will be in their respective folders. Note that the '''Modelling\TUFLOW''' folder still contains all files from <u>[[Tutorial_M06#Part_3_-_Rainfall_Control_File | TUFLOW Tutorial Module 6 (part 3).]]<br/u>.

== QGIS Workspace ==
Set up the QGIS workspace to contain the model elevation data, and save the workspace:
<ol>
<li>In Windows File Explorer, navigate to the '''Modelling\TUFLOW\model\grid''' folder. Drag and drop the '''DEM.tif''' file into QGIS.
<li>Change the symbology of the DEM:
* In the QGIS Layers panel, right click the '''DEM''' file and select 'Properties'.
Line 59 ⟶ 60:
*Click 'Apply' and 'OK'.
<br>

<li>Create a hillshade of the DEM:
*Right click on the '''DEM''' file in the QGIS Layers Panel and select 'Duplicate Layer'.
Line 69 ⟶ 70:
*Click 'Apply' and 'OK'.
<br>
{{Video|name=videoanimation_TC1_initialisation_05a.mp4|width=1236}}<br>
<li> Save the QGIS workspace:
*Go to Project > Save As.
*Navigate to the '''TUFLOW_CATCH_Module_01''' folder and type CATCH_M01 assave the filenameworkspace with the extensionas '''TC01.qgz'''.
