QGIS is used to import the check files and review the topographic modification cutting through the embankment, and the layered flow constriction. <br>
Line 14 ⟶ 11:
Review the check files:
<ol>
<li>Open the files, either:
:*Within the QGIS Browser Panel, navigate to '''Module_04\TUFLOW\check\M04_5m_001_Check.gpkg''' and double click the following layers, or
::*'''M04_5m_001_lfcsh_uvpt_check_P'''▼
:*In File Explorer, navigate to the '''Module_04\TUFLOW\check''' folder, drag and drop the '''M04_5m_001_Check.gpkg''' into the QGIS workspace and select the layers above (hold Ctrl to select multiple).
<li>Navigate to the '''Module_04\TUFLOW\check''' folder and open the '''M04_5m_001_DEM_Z.tif''' layer into QGIS.
▲*'''M04_5m_001_zsh_zpt_check_P'''
▲*'''M04_5m_001_lfcsh_uvpt_check_P'''
<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>Use the 'Apply GPKG Layer Names'.
Line 24 ⟶ 22:
<li>The zsh_zpt_check file displays the elevation points changed by Z shape topographic update and the TUFLOW styling provides an indication of the elevation difference.<br>

<li>The lfcsh_uvpt_check file shows the Zpts where the 2d_lfcsh is applied as a thin line. Only the cell sides have the flow constriction applied. The attribute table shows the values specified in the 2d_lfcsh and the final elevation of the invert level after applying the Z shape. <br>
