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:
- Go to Plugins > TUFLOW > Editing > Configure / Create TUFLOW Project.
- 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.
- Click 'OK' and save the QGIS workspace by selecting Project > Save As.
- Set the QGIS workspace projection to EPSG:32760, see Set the Projection.
Method
Inspect cumulative rainfall and rainfall rate outputs:
- Open the TUFLOW Viewer.
- Select File > Load Results. Navigate to the M06_5m_001.tcf in the Module_06\TUFLOW\runs folder and open it.
- Three 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.
- Manning n: the Manning n values over time.
- Use the Plot Time Series tool to see the time series of the cumulative rainfall and rainfall at a point:
- Add multiple points across the grid. Notice they all have an equal cumulative rainfall and rainfall rate applied.
- Use the Plot Time Series tool to see the time series of the depth and manning's n at a point and turn on the 'Manning n' map output from the Results Type to see the manning's n value change with depth:
Conclusion
- The cumulative rainfall and rainfall rate derived from global rainfall were inspected at a point.
- The manning's n value was inspected as it varied in relation to depth.
