Tutorial M06 002 Results QGIS update V2 draft

Introduction

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

Method

Inspect cumulative rainfall, rainfall rate and loss outputs:

1. Open the Map Outputs and Time Series results, either:
   • Within the QGIS Browser Panel drag the following layers into the QGIS workspace, or

   • Module_06\TUFLOW\results\M06_5m_002.xmdf > loads the map output mesh results
   • Module_06\TUFLOW\results\plot\M06_5m_002.tpc > loads the time series output results

   • In File Explorer, navigate to the files above and drag and drop them into the QGIS workspace.
2. Open an additional file from within the QGIS Browser Panel, drag the following layer into the QGIS workspace:

   • Module_06\TUFLOW\model\gis\M06_5m_002.gpkg\2d_mat_M01_001_R > loads the model materials layer.

3. One additional output type appears:
   • Cum. Mat. Loss: the total rainfall losses applied as initial and continuing losses specified in the materials file.

   To select this result type in the Layers Panel, select M06_5m_002, then in the Layer Styling panel, in the 'Datasets' tab, select Cum.Mat.Loss.

4. Select the M06_5m_002 file in the Layers panel and click on the 'TUFLOW Viewer Plot Window' icon. The plot widget will open.
   
5. One additional output type appears in the 'Datasets' tab:

   • Cum. Mat. Loss: the total rainfall losses applied as initial and continuing losses specified in the materials file.

6. Use the Time Series Plot tool to see the Datatype 'cum.mat.loss' to see Cumulative Material Loss time series. Use the Draw tool to select various locations. Notice the variation due to the assigned materials ID:
   Note: the current time can be selected by right clicking into the graph window and tick 'show current time'.
   
   
   

   
   

7. Use the Time Series Plot 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:
   Note: the secondary axis can be selected by right clicking in the plot window and on the line that needs to be show on the secondary axis, and tick 'Move to secondary axis'.
   
   
   

   
   
   

Conclusion

• The cumulative rainfall, rainfall rate and rainfall material losses derived from rainfall polygons were inspected with the TUFLOW Viewer 2.
• For further functionality, see TUFLOW Viewer 2 documentation.
