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>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
