The HX lines must be broken between the nodes. This is a requirement of a linked Flood Modeller – TUFLOW model.
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 FC02.06 and FC02.01d along the tributary 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>

<li>Once all the CN and HX lines have been digitised along the tributary, save the file and export into .MIF / .MID format for import into TUFLOW.</li>▼

! style="background-color:#005581; color:white;"| The digitised direction of the HX and CN lines is not important. The CN lines however should be digitised approximately perpendicular to the direction of flow. Two CN lines are digitised for each node and connected to the HX boundary lines along the left and right banks. The HX boundary lines should be digitised along the top of each bank such that the width between the lines approximately correlates to the width of the 1D channel.▼
