Tutorial M10 002 Results QGIS TUFLOW Viewer V2

Introduction

QGIS is used to view the bathymetry and water levels with the TUFLOW Viewer V2. For viewing of the 2D map results, see Module 1.

Method

Inspect bathymetry (dynamic bed level) and water level outputs:

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

   • Module_10\TUFLOW\results\M10_5m_002.xmdf > loads the map output mesh results

   • In File Explorer, navigate to the file above and drag and drop it into the QGIS workspace.
2. In the Layers panel, select M10_5m_002. Then in the Layer Styling panel, select the 'Bathymetry' output type in the 'Datasets' tab. It shows elevations at cell corners (ZH points) over time based on the variable geometry (2d_vzsh).
3. Click on the 'TUFLOW Viewer Plot Window' icon. The plot widget will open.
   
4. Use the Cross Section Plot tool to plot the 'dynamic bed level' and 'bed elevation' (elevation at the beginning of the simulation) at the location of the dam break. The dam break is triggered by the water level at the point.
   
   
   
   

   
   

5. Use the Time Series Plot tool to see the time series of the water level at the location of the water level trigger point from 2d_vzsh_M10_dambreak_002_P. The dam break begins when the water level at the point reaches 60m:
   
   
   
   

Conclusion

• A cross section of the dam wall was inspected showing the bathymetry changing over time using TUFLOW Viewer V2.
• Time series water level was inspected at the location of the water level trigger point.
• For further functionality, see TUFLOW Viewer documentation.
