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.
