This tutorial introduces:
:*[[Check_Files_2d_DEM_Z | _DEM_Z]]
:*[[Check_Files_2d_zsh_zpt | _zsh_zpt_check_P]]
:*[[Check_Files_2d_bg_uvpt_check | _bg_uvpt_check_P]]
<ol>
<li>Open the files, either:
:*Within the QGIS Browser Panel, navigate to '''Module_04\TUFLOW\check\M04_5m_002_Check.gpkg''' and double click the following layerslayer, or
::*'''M04_5m_002_zsh_zpt_check_P'''
::*'''M04_5m_002_bg_uvpt_check_P'''
:*In File Explorer, navigate to the '''Module_04\TUFLOW\check''' folder, drag and drop the '''M04_5m_002_Check.gpkg''' into the QGIS workspace and select the layerslayer above (hold Ctrl to select multiple).
<li>Navigate to the '''Module_04\TUFLOW\check''' folder and open the '''M04_5m_002_DEM_Z.tif''' layer into QGIS.
<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>Use the 'Apply GPKG Layer Names'.
<li>The lfcsh_uvpt_checkbg_uvpt_check file shows the Zpts where the 2d_lfcsh2d_bg 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_lfcsh2d_bg and the final elevation of the invert level after applying the Z shape. <br> ▼<li>The DEM_Z grid shows the final elevations used for the model calculations. Change the styling and inspect the area of the embankment is lowered. See <u>[[Tutorial_M02_001_Check_Files_QGIS_GPKG | Module 2]]</u> for more information on how to review topographic modifications. Note: The DEM_Z appears different to the input DEM as the resolution of the DEM_Z is coarser (2.5m) than the input file (0.5m).<br>
<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>
