<li>Import in an empty 2d_bc_empty.TAB layer from within the TUFLOW\model\mi\empty folder and save as
<li>Open the 1D_2D_HX_Links.TAB GIS layer from <b>Module_Data\Module_01\mi</b> folder. Select all objects from within this layer, copy and paste into
<li>Interrogate one of the lines running along the banks of the watercourse. These lines are the 1D/2D boundary links and have been assigned a type ‘HX’.</li>
<li>Interrogate one of the lines connecting the x1D node to the HX line. These are the connection or ‘CN’ lines that read the water level from Flood Modeller and transfers this to the HX line. </li>

<li>Save the file and export into .MIF / .MID format for import into TUFLOW.</li>▼
<li>Note that where there are junctions within the Flood Modeller 1D model (i.e. at structures), both the upstream and downstream nodes are connected to TUFLOW. The HX line broken between the nodes. This is a requirement of a linked Flood Modeller – TUFLOW model. </li>
In the figure below, the HX lines are broken between FC01.35 and FC01.34 as a culvert is located between these nodes.

<li>The CN and HX lines between nodes along the tributary between nodes FC02.06 and FC02.01d have not been digitised. Digitise these lines to connect the nodes to the 2D domain. The figure below shows how the nodes are connected at the confluence. Note that all Flood Modeller nodes at the junction are present within the 1d_x1D_nodes layer, and are connected to the 2D domain. The HX lines are broken around the junction. </li>
