QGIS is used to import the check files and review the modified elevations between both model runs. 
 

= Method =
This tutorial introduces:
:*[[Check_Files_2d_DEM_Z | _DEM_Z]]
:*[[Check_Files_2d_sh_obj | _sh_obj_check_R]]
:*[[Check_Files_2d_DEM_M | _DEM_M]]

Review the check files: 
<ol>
<li>Open the following files from the '''Module_02\TUFLOW\check''' folder:
:*'''M02_5m_001_DEM_Z.tif'''
:*'''M02_5m_002_DEM_Z.tif'''
:*'''M02_5m_002_sh_obj_check_R.shp'''
<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>The DEM_Z grid shows the final elevations including any topographic modifications used for the model calculations.
<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.
<li>Use the Profile Tool plugin to compare the DEM_Z files from both model runs. 
 
[[File:Animation M02 Check 002 01.gif]] 
 
<li>The first no merge region raises all elevation points to a single value. 
 
[[File:Animation M02 Check 002 03.gif]] 
 
<li>The second no merge region adds a specified value to all elevation points. 
 
[[File:Animation M02 Check 002 02.gif]] 
 
<li>The merge region used for the farm dam rehabilitation interpolates between all perimeter elevation points. 
 
[[File:Animation M02 Check 002 04b.gif]] 
 
<li>The merge region with negative Shape_Option attribute cuts through the embankment. The manually added vertices allow the modification to follow the cross section of the channel. 
 
[[File:Animation M02 Check 002 05b.gif]] 
 
<li>Zoom to the landscape files and review the TIN triangles and elevations created by the points, line and region using the merge option. 
 
[[File:Animation M02 Check 002 06b.gif]] 
 
<li>Open the following file from the '''Module_02\TUFLOW\check''' folder:
:*'''M02_5m_002_DEM_M.tif'''
<li>Right click on the DEM_M file and select 'Properties'.
<li>From 'Render Type', select 'Palletted/Unique Values'.
<li>Click 'Classify', five unique values appear referring to the material specified in the 2d_mat_M02_landscape and materials.csv file. Click 'OK'.
<li>The DEM_M shows the final material ID values. Change the labels to match the material class as shown below.

= Conclusion =
:*The topographic modifications representing different development sites were assessed using the Profile Tool.
:*The DEM_M grid was used to review the land use.
