Style the Layers

Styling can be done in many ways. We will change display symbology of the DTM dataset:

1. In the QGIS Layers panel, click the tick box next to the 2d_bc_code and 2d_iwl_R layers so the underlying DTM dataset can be viewed.
2. Right click on the DTM Grid file and select 'Properties'.
   • In the Symbology tab, under 'Band Rendering' select the following options:

   • Render type: Hillshade
   • Z Factor: 3

   • Click 'Apply' and 'OK'.
   
   

   
   

Save the QGIS Workspace

1. From the top dropdown menu options, go to Project > Save As.
2. Navigate to the file location containing the TUFLOW folder and save the workspace with the extension, .qgz.
