<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.'''
# Remove the Start Time, End Time, and 2D Timestep parameters from the TCF, as these are read from the Flood Modeller .ief file in a linked Flood Modeller-TUFLOW model. If they are left in place the Flood Modeller settings will override the TUFLOW settings. This is done by adding an exclamation mark in front of each of the following commands.<br><font color="green"><tt>! SIMULATION TIME CONTROL COMMANDS</tt></font><br><font color="blue"><tt>Timestep </tt></font> <font color="red"><tt>== </tt></font> 1.5 <font color="green"><tt>!

▲<li>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.
▲<li>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>
▲<li>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

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.
