Introduction

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

Method

Inspect bathymetry and water level outputs:

Open the TUFLOW Viewer.
- Within the QGIS Browser Panel drag the following layers 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 files above and drag and drop them into the QGIS workspace.
Open an additional file from within the QGIS Browser Panel, drag the following layer into the QGIS workspace:
- Module_10\TUFLOW\model\gis\M10_002.gpkg\2d_vzsh_m10_dambreak_002_p > loads the variable z shape layer representing the dam break.
Select the 'Bathymetry' output type in the Result Type panel. It shows elevations at cell corners (ZH points) over time based on the variable geometry (2d_vzsh).
Use the Section to plot the bathymetry 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.
Use the Plot Time Series 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:

A cross section of the dam wall was inspected showing the bathymetry changing over time using TUFLOW Viewer 2.
Time series water level was inspected at the location of the water level trigger point.
For further functionality, see TUFLOW Viewer 2 documentation.
