Introduction

QGIS is used to create, import and view input data.

Method

Set up the GeoPackage Database:

  1. Navigate to the Module_10\TUFLOW\model\gis folder. Save a copy of M10_003.gpkg as M10_004.gpkg.

Create a 2d_sa polygon downstream of the dam wall:

  1. Click on the ‘Import Empty File’ symbol from the TUFLOW Plugin toolbar.
  2. Select '2d_sa' from the Empty Type list.
  3. In the Run ID box write: 'M10_dambreak_004'.
  4. Tick the 'Regions' Geometry Type.
  5. 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'.
  6. The 2d_sa file appears in the Layers panel.
  7. Right click on the 2d_sa_M10_dambreak_004_R and toggle on Editing.
  8. Select 'Add Polygon Feature'.
  9. Digitise a polygon downstream of the dam wall within the creek channel.
  10. An attributes dialog displays, enter the following attributes:
    • Name: dambreak
  11. Click 'OK' and turn off editing to save the edits.
