= TUFLOW Project Re-Configuration =
Re-configure the TUFLOW project to use and save empty files to the correct folder:<br>
<ol>
<li>Go to Plugins > TUFLOW > Editing > Configure / Create TUFLOW Project.
<li>Change the folder which contains TUFLOW to the '''Module_06''' folder. This is the only change required, the model folder structure and template empty files are supplied from previous model.<br>
Note: The 'results' and 'check' folder get automatically created when the TUFLOW model is run. <br>
<li>Click 'OK' and save the QGIS workspace by selecting Project > Save As.<br>
<br>

<li>Set the QGIS workspace projection to EPSG:32760, see <u>[https://wiki.tuflow.com/index.php?title=Tutorial_Site_Familiarisation_QGIS#Set_the_Projection Set the Projection]</u>.

= Method =
Set up the GeoPackage Database:
<ol>
<li>Within the QGIS Browser Panel, right click on 'Favorites' and select 'Add a Directory...'.
<li>Navigate to the '''Module_06''' folder and select it.
</ol>
Create a 2d_rf layer with digitised polygons based on the input rainfall hyetographs:
<ol>
<li>Click on the ‘Import Empty File’ tool from the TUFLOW
<li>Select '2d_rf' from the Empty Type list.
<li>In the Run ID box write: 'M06_polygons_002'.
<li>Tick the 'Regions' Geometry Type
<li>In the Spatial Database Options, select 'All to one'. Navigate to the '''Module_06/TUFLOW/model/gis''' folder and select '''M06_002.gpkg'''. Click Save and hit 'OK'.
<li>The '''2d_rf_M06_polygons_002_R''' appears in the QGIS Layers Panel.
</ol>
The same catchment breakup is used as the 2d_sa layer:
<ol>
▲<ol><li>Navigate to the '''Module_06\TUFLOW\model\gis''' folder and open the '''2d_sa_M01_001_R.shp''' layer in QGIS.
<li>Load in the '''2d_sa_M01_001_R''' layer from '''M06_002.gpkg''', either:
:*Within the QGIS Browser Panel, navigate to '''M06_002.gpkg''' and double click the layer, or
:*In File Explorer, drag and drop the '''M06_002.gpkg''' into the QGIS workspace and select the layer.
<li>Copy and paste the polygons from the 2d_sa layer into the 2d_rf: <br>
