<li>Read in the GIS layers used to create Water Level Lines along the Flood Modeller component of the model (optional).
<li>Add a reference to the ESTRY Control File.
<li>Update references to the TBC and TGC.
</ul>The following steps outline how to apply these updates:
# In the \FMT_Tutorial\FMT_M01\TUFLOW\runs folder, save a copy of the TUFLOW file created as a part of [[Tutorial_M02 |Module 2]] ('''M02_5m_001.tcf''') as '''FMT_M01_001.tcf.'''

#Read in the GIS layers of the Flood Modeller Nodes. Place the below command line anywhere in the .tcf. It is good practice to create a section within the .tcf to reference all 1D commands:<br><u>'''QGIS - SHP'''</u><br><font color="blue"><tt>Read GIS X1D Nodes</tt></font> <font color="red"><tt>== </tt></font>..\model\gis\1d_x1d_FMT_M01_nodes_001_P.shp <font color="green"><tt>!

#Add commands to read in the GIS layers referencing Water Level Lines drawn along the Flood Modeller component of the model:<br><u>'''QGIS - SHP'''</u><br><font color="blue"><tt>Read GIS X1D Network</tt></font> <font color="red"><tt>== </tt></font>..\model\gis\1d_x1d_FMT_M01_nwk_001_L.shp <font color="green"><tt>!

GIS layer containing WLLs for visualising 1D results in 2D (optional)</tt></font><br>The addition of TUFLOW Water Level Lines (WLL) allows the Flood Modeller 1D results to be visualised within the TUFLOW 2D map outputs. They provide a means by which to remove the gaps in the map outputs where the 1D Flood Modeller domains are located and the 2D cells are deactivated. To do this, TUFLOW requires a 1D_WLL layer to define the cross sections locations, and a 1d_nwk layer that defines the river centre line. The layers are not used in the hydraulic calculations and their inclusion is not always required. The Dist_for_Add_Points determines the intervals in metres at which interpolation points are inserted along each WLL.
#Add commands to read in an ESTRY Control File which contains references to some of the culverts present on the floodplain:<br><font color="blue"><tt>ESTRY Control File</tt></font> <font color="red"><tt>== </tt></font>..\model\FMT_M01_001.ecf <font color="green"><tt>!Reference the ESTRY Control File </tt></font>
#Update the links to the Geometry control file, the Boundary Condition control file and the bc_dbase file:<br><font color="blue"><tt>Geometry Control File</tt></font> <font color="red"><tt>== </tt></font>..\model\FMT_M01_001.tgc <br><font color="blue"><tt>BC Control File</tt></font> <font color="red"><tt>== </tt></font>..\model\FMT_M01_001.tbc <br><font color="blue"><tt>BC Database</tt></font> <font color="red"><tt>== </tt></font>..\bc_dbase\bc_dbase_FMT_M01.csv
</ol>
This concludes the changes needed to be made to the TCF.

= Review Check Files =
=== Review Boundaries and 1D/2D Links ===
From the TUFLOW\check\2d\ folder open within QGIS:
*FMT_M02_001_1d_to_2d_check
*FMT_M02_001_sac_check
The _1d_to_2d_check layer highlights the location of all 1D/2D boundary links within the model. In this case it should show the HX boundaries that have been digitised along the river banks.
The _sac_check layer highlights the lowest 2d cells within the SA boundary polygon to which inflow is first distributed.
=== Review Bank Elevations ===
From the TUFLOW\check\2d\ folder open within QGIS:
*FMT_M01_001_zln_zpt_check_P
The _zln_zpt_check layer highlights the cells whose elevations have been modified by z lines to represent the bank crests of the watercourse.
