QGIS Result Viewing

  1. Open TUFLOW Viewer from the TUFLOW Plugin toolbar.

  2. Open the simulation results. Select File > 'Load Results'. Navigate to the TUFLOW\runs folder and select TS02_5m_001.tcf.
  3. When asked 'Do you want to open result GIS Layer?', select 'Yes'. Five new files will load to the QGIS Layers Panel:
    • TS02_5m_001_swmm_ts_P: 1D SWMM node junction and outlet water level results
    • TS02_5m_001_swmm_ts_L: 1D SWMM conduit flow results
    • TS02_5m_001_PLOT_P: 1D ESTRY and 2D plot output water level and velocity results (Note: There are no ESTRY results from this simulation)
    • TS02_5m_001_PLOT_L: 1D ESTRY and 2D plot output flow results (Note: There are no ESTRY results from this simulation)
    • TS02_5m_001: 2D TUFLOW results

Pipe Flow Results

  1. In the QGIS Layers Panel, right click TS02_5m_001_swmm_ts_L and select 'Zoom to Layer(s)'.
  2. In the TUFLOW Viewer Panel, click 'Play Through Timesteps' Play through timesteps icon.png. Observe how the TS02_5m_001_swmm_ts_L results change color depending on the amount of flow within the 1D pipes.


  3. In the QGIS Layers Panel, select (left click) TS02_5m_001_swmm_ts_L.
  4. Use the 'Select Features' tool to highlight pipes within the network (hold Shift to select multiple).
  5. Click on the 'Flow' dataset under 'Result Type' in the TUFLOW Viewer 'Time Series' list.


  6. In the QGIS Layers Panel, select (left click) TS02_5m_001_swmm_ts_P.
  7. Use the 'Select Features' tool to highlight node junctions within the network (hold Shift to select multiple).
  8. Click on the 'Lateral Inflow' and 'Total Flow' dataset under 'Result Type' in the TUFLOW Viewer 'Time Series' list.
    • Lateral Inflow: Represents the flow entering the pipe network via the 1D/2D pit surface connections.
    • Total Inflow: The sum of all flows, including flows from the 1D/2D pit and upstream 1D pipe.


Pipe Long-section Results

  1. In the QGIS Layers panel, right click TS02_5m_001_swmm_ts_L and select 'Zoom to Layer(s)'.
  2. Select two pipe segments, the long-section between the pipes will be plotted.
  3. Click on the 'Water level', Max Water Level' and 'Culverts and Pipes' datasets in the Result Type panel of TUFLOW Viewer.
  4. Move the time slider to view how the water level varys in the pipe during the simulation.
