QGIS is used to create, import and view input data.
Method
Set up the GeoPackage Database:
- Navigate to the Module_10\TUFLOW\model\gis folder. Save a copy of M10_001.gpkg as M10_004.gpkg.
Create a 2d_sa polygon downstream of the dam wall:
- Click on the ‘Import Empty File’ symbol from the TUFLOW Plugin toolbar.
- Select '2d_sa' from the Empty Type list.
- In the Run ID box write: 'M10_dambreak_004'.
- Tick the 'Regions' Geometry Type.
- In the Spatial Database Options, select 'All to one'. Navigate to the Module_10/TUFLOW/model/gis folder and select M10_004.gpkg. Click Save and hit 'OK'.
- The 2d_sa file appears in the Layers panel.
- Right click on the 2d_sa_M10_dambreak_004_R and toggle on Editing.
- Select 'Add Polygon Feature'.
- Digitise a polygon downstream of the dam wall within the creek channel.
- An attributes dialog displays, enter the following attributes:
- Name: dambreak
- Click 'OK' and turn off editing to save the edits.
