<li>Observe that Pipe16 and Pipe18 in the layer '''1d_nwk_FMT_M02_Pipes_001_L.shp''' representing the pipe network have been snapped to node “FC01.11” of the layer '''1d_x1d_FMT_M01_nodes_002_P.shp'''. As an additional node hasn’t been manually added the Flood Modeller-ESTRY link at this location is assumed to be an “X1DH” link. If you open the attribute table you will be able to see that the <b>Conn_1D_2D</b> attribute for “Pipe16” and “Pipe18” has been left blank as an “X1DH” link is used by default and therefore doesn’t need to be specified.

<li>Open the Flood Modeller network (.DAT) file '''FMT_M01_002.dat''' in the Flood Modeller Pro interface. Observe that the updated network file terminates at a stage-time boundary unit named “DSBDY”. This does not need to contain any time-varying data as this data will be overridden by the water levels provided by ESTRY.

<li>Create a new folder entitled '''xs''' in the '''TUFLOW\model''' folder. Copy the layer '''1d_xs_FMT_M02_creek_001_L.shp''' and the csv files listed below from the '''Module_data\Module_02\Creek''' folder into the newly created '''TUFLOW\model\xs''' folder. These csv files in combination with the layer '''1d_xs_FMT_M02_creek_001_L.shp''' will be used to define the geometry and locations of the river channel cross sections.

<li>Copy the csv file '''Weir_HT.csv''' from the '''Module_data\Module_02\Creek''' folder to the '''TUFLOW\bc_dbase''' folder. This csv file contains the stage time data that will be applied at the downstream boundary node 'DS_BC'. A constant stage value of 35.5m AOD has been applied .

<li>An additional row needs to be added to '''bc_dbase_FMT_M02.csv''' to apply the stage-time values from '''Weir_HT.csv'''. The revised bc_dbase should look like the figure below:
