Introduction

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

Method

Inspect cumulative rainfall, rainfall rate and loss outputs:

  1. Open the TUFLOW Viewer.
  2. Select File > Load Results. Navigate to the M06_5m_002.tcf in the Module_06\TUFLOW\runs folder and open it.
  3. One additional output type appears in the Result Type panel:
    • Cum. Mat. Loss: the total rainfall losses applied as initial and continuing losses specified in the materials file.
  4. Use the Plot Time Series tool to see the cumulative material loss time series. Notice the variation due to the assigned materials ID:



  5. Use the Plot Time Series tool to see the time series of the cumulative rainfall, rainfall rate and losses at a point. Notice the results vary spatially due to the 2d_rf polygons and 2d_mat regions:




Conclusion

  • The cumulative rainfall, rainfall rate and rainfall material losses derived from rainfall polygons were inspected with the TUFLOW Viewer.
  • For further functionality, see TUFLOW Viewer.
