Tutorial M10 001 Results QGIS update V2 draft
Introduction
QGIS is used to view the dam break scenario via the bathymetry (the 'dynamic bed levels') and water depth with the TUFLOW Viewer 2. For viewing of the 2D map results, see Module 1.
Method
Inspect bathymetry (dynamic bed elevation representing the dam break scenario) and water depth outputs:
- Within the QGIS Browser Panel drag the following layers into the QGIS workspace, or
- Module_10\TUFLOW\results\M10_5m_001.xmdf > loads the map output
- In File Explorer, navigate to the files above and drag and drop them into the QGIS workspace.
- In the 'Layer' Panel, click on M10_5m_001 and select the 'Bathymetry' output type in the 'Datasets' tab. It shows elevations at cell corners (ZH points) over time based in the variable geometry (2d_vzsh).
- Use the Cross Section Plot tool to plot the bed elevation and dynamic bed elevation (elevation at the beginning of the simulation) at the location of the dam break. The dam break begins at 1 hour and takes 15 minutes to fully develop:
- In the 'Layer' Panel, click on M10_5m_001 and select the 'Depth' output type in the 'Datasets' tab. Use the Time Series Plot tool to see the time series of the bathymetry and water level at the location of the dam break, whilst viewing the depth result type. Due to the IWL, water is within the dam at the beginning of the simulation
Conclusion
- A cross section of the dam wall was inspected showing the bathymetry changing over time.
- Time series of bathymetry and water level were inspected at the location of the dam break.
- For further functionality, see TUFLOW Viewer 2 documentation.
