Tutorial M11 002 Results QGIS TUFLOW Viewer V2
Introduction
QGIS is used to view the water level in the 1D network, moving between the 1D and 2D and in the 2D floodplain using TUFLOW Viewer V2. For viewing of the 2D map results, see Module 1.
Method
Inspect water level and velocity outputs:
- Open the Map Outputs results, either:
- Within the QGIS Browser Panel drag the following layers into the QGIS workspace, or
- Module_11\TUFLOW\results\M11_5m_002.xmdf > loads the map output
- Module_11\TUFLOW\results\plot\M11_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.
- In the Layers Panel, select M11_5m_002. Then in the Layer Styling panel, select the 'Water Level' and 'Vector Velocity' output types in the 'Datasets' tab. The resolution of the vector velocity is different between the 1D and 2D sections. The 1D section shows vectors at the water level lines (2d_WLL) every 2.5m, the 2D section shows vectors based on the 2D cell resolution, every 5m. The direction of the vectors shows water moving between the 1D and 2D domain.
- Use the Time Series Plot tool to plot a time series of flow through the 1D bridge and weir at the downstream crossing. Select 'Flow' from the Data Types. Water is overtopping the bridge through the 1D weir:
- Use the Time Series Plot tool to plot a time series of flow through the 1D bridge at the upstream crossing. Select 'Flow' from the Data Types. Water is overtopping the bridge in 2D:
Conclusion
- Water level and velocity map outputs from the 1D and 2D were inspected using TUFLOW Viewer V2.
- Time series of flow was inspected at the both bridges and the weir.
- For further functionality, see TUFLOW Viewer documentation.
