Introduction

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

TUFLOW Project Re-Configuration

Re-configure the TUFLOW project to use and save empty files to the correct folder:

  1. Go to Plugins > TUFLOW > Editing > Configure / Create TUFLOW Project.
  2. Change the folder which contains TUFLOW to the Module_07 folder. This is the only change required, the model folder structure and template empty files are supplied from previous model.
    Note: The 'results' and 'check' folder get automatically created when the TUFLOW model is run.
  3. Click 'OK' and save the QGIS workspace by selecting Project > Save As.

  4. Set the QGIS workspace projection to EPSG:32760, see Set the Projection.


Method

Navigate to the Module_07\TUFLOW\model\gis folder:

  • Drag and drop the 2d_code_M01_001_R.shp file into the workspace, or
  • Select Layer > Add layer > Add Vector Layer and navigate to the Module_07\TUFLOW\model\gis folder.
  • Use the 'Apply TUFLOW Styles to Open Layers'.

Create quadtree nesting layer:

  1. Click on the ‘Import Empty File’ symbol from the TUFLOW Plugin toolbar.
  2. Select '2d_qnl' from the Empty Type list.
  3. In the Run ID box write 'M07_001'.
  4. Tick the 'Regions' Geometry Type and hit 'OK'. The 2d_qnl (quadtree nesting layer) file appears in the Layers panel.
  5. Right click on the 2d_qnl_M07_001_R and toggle on Editing.
  6. Select 'Add Polygon Feature' and digitise a polygon around the creek.
  7. Terminate the polygon by right clicking and write '2' into the 'Nest_Level' attribute.
  8. Turn off editing to save the edits.



Conclusion

  • A 2d_qnl layer was digitised surrounding the creek.
