Introduction

QGIS is used to view the cumulative rainfall and rainfall rate with the TUFLOW Viewer. For viewing of the 2D map results, see Module 1.

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_06 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

Inspect cumulative rainfall and rainfall rate outputs:

  1. Open the TUFLOW Viewer.
  2. Select File > Load Results. Navigate to the M06_5m_001.tcf in the Module_06\TUFLOW\runs folder and open it.
  3. Two additional output types appear in the Result Type panel:
    • RF Cumulative: the cumulative rainfall in mm over time.
    • RF Rate: the rainfall rate in mm/hr over time.
    These outputs are inclusive of any boundary adjustments (made in the bc_dbase) and rainfall losses (applied in the materials file).
  4. Use the Plot Time Series tool to see the time series of the cumulative rainfall and rainfall at a point:

     

  5. Add multiple points across the grid. Notice they all have an equal cumulative rainfall and rainfall rate applied.

     


Conclusion

  • The cumulative rainfall and rainfall rate derived from global rainfall were inspected at a point.
