<li>Open the files, either:
<ol><li>In:*Within Filethe QGIS Browser ExplorerPanel, navigate to the '''Module_10\TUFLOW\check''' folder, drag and drop '''M10_5m_001_DEM_Z\M10_5m_001_Check.tifgpkg''' and thedouble '''M10_5m_001_Check.gpkg''' intoclick the QGIS workspace and select thefollowing layers (hold Ctrl to select multiple), or

<li>Within the QGIS Browser Panel, navigate to '''Module_10\TUFLOW\check\M10_5m_001_Check.gpkg''' and double click on the layers to open them.</ol>

:*In File Explorer, navigate to the '''Module_10\TUFLOW\check''' folder, drag and drop the '''M10_5m_001_Check.gpkg''' into the QGIS workspace and select the layers above (hold Ctrl to select multiple).
<li>Navigate to the '''Module_10\TUFLOW\check''' folder and open the '''M10_5m_001_DEM_Z.tif''' layer into QGIS.
<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>Use the 'Apply GPKG Layer Names'.
<li>The DEM_Z grid shows the final elevations (at time 0) used for the model calculations. The elevation changes due to the dambreak are inspected in the Results section.<br>
<li>The zsh_zpt_check file contains the Zpts modified by the 2d_zsh layers with updated elevation, change in elevation and source layer. The Shape_Width attribute is specified the same as the cell size, a thick breakline is used with entire cells being modified. The TUFLOW style colour codes the symbols based on the amount raised, or lowered. <br>

<br>
<li>The vzsh_zpt_check file contains information on the elevation points that change over time, elevation change, final elevation and trigger conditions.<br>
<li>The sh_obj_check file displays the TIN triangles created by TUFLOW during the model initialisation and is useful to review for all merge polygons.<br>

<li>The grd_check is the 2D grid defined by the 2d_code layer and contains a region object for each cell with attributes, e.g. the IWL. <br>

<li>The sac_check contains information on the lowest cells for each SA boundary region. The upstream 2d_bc QT inflow was replaced with a 2d_sa inflow.
<li>The bcc_check contains information on the 2D boundaries, it shows the cells conveying water out of the model selected by the 2d_bc HQ type boundary (based on a slope).<br>
