Tutorial M10 005 Results QGIS update V2 draft

Introduction

QGIS is used to view the water using Non-Newtonian fluids using TUFLOW Viewer 2. The results are compared to Newtonian fluids from Part 4. For viewing of the 2D map results, see Module 1.

Method

Inspect water levels of the non-Newtownian outputs:

Open the Map Outputs results, either:

• Within the QGIS Browser Panel drag the following layers into the QGIS workspace, or

• Module_10\TUFLOW\results\M10_5m_005.xmdf > loads the map output mesh results

• 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_005 then in the Layer Styling panel, select the 'Water Level' map output type in the 'Datasets' tab and toggle on 'Maximum'. Inspect the difference in water levels between M10_5m_004 and M10_5m_005:

Use the Plot Cross Section tool to see the cross section of the water level and bed level at the the edge of the flood extent.

Compare the M10_5m_004 and M10_5m_005 results. The curvature of water level in M10_5m_005 demonstrates the Non-Newtonian fluid qualities. The viscosity of the fluid has changed, becoming more solid, due to the shear force as the fluid moves down the catchment:

Conclusion

• The water level outputs of the Non-Newtonian fluid were inspected and compared to a Newtonian fluid from Part 4.
• For further functionality, see TUFLOW Viewer 2 documentation.
