Flood Modeller Tutorial Module01 Provisional: Difference between revisions

<li> 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'''. </li>▼

<li> 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. </li><li> Add an exclamation mark in front of each of the following commands.<br><font color="green"><tt>! SIMULATION TIME CONTROL COMMANDS </tt></font> ▼

:<font color="blue"><tt>Timestep </tt></font> <font color="red"><tt>== </tt></font> 1.5 <font color="green"><tt>! Specifies a 2D computational timestep of 1.5 seconds </tt></font>▼

:<font color="blue"><tt>Start time </tt></font> <font color="red"><tt>== </tt></font> 0 <font color="green"><tt>! Specifies a simulation start time of 0 hours </tt></font>▼

:<font color="blue"><tt>End Time </tt></font> <font color="red"><tt>== </tt></font>3 <font color="green"><tt>! Specifies a simulation end time of 3 hours</tt></font> ▼

<li> We need to 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: ▼

</li><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> </li><li>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. </li><li>The Dist_for_Add_Points determines the intervals in metres at which interpolation points are inserted along each WLL. </li>▼

<li> Add commands to read in an Esty 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><li> Finally, 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 </li>▼

</ol>This concludes the changes that we need to make to the .tcf▼
