Navigate to the '''Module_04\Tutorial_Data''' folder. Copy and save all the below layers into the '''Module_04\TUFLOW\model\gis''' folder: <br>
:*'''2d_bg_M04_002_L'''
 
:*'''2d_po_M04_001_L'''
:*'''2d_po_M04_001_P'''
:*'''2d_zsh_M02_cut_002_R'''
 
Investigate the supplied files:
<ol>
<li>Open the files'''2d_bg_M04_002_L''' file, either: <br>
:*Drag and drop the .shp filesfile into the QGIS workspace, or
:*Select Layer > Add layer > Add Vector Layer and navigate to the '''Module_04\TUFLOW\model\gis''' folder.
<li>The 2d_zsh file cuts through the road embankment, see <u>[[Tutorial_M02 | Module 2]]</u> for more information.<br>
<li>The 2d_bg represents the bridge in 2D, it has layers of varying blockage and form loss for the “pier layer” and the “super structure layer”, which consists of the “deck layer” and the “rail layer”. <br>
Refer to the <u>[https://docs.tuflow.com/classic-hpc/manual/2023-03/TwoD-Domains-1.html#bg-layer-4 TUFLOW Manual]</u> for more information on the attributes of the 2d_bg layer.<br>

<li>The 2d_po files include a structure group output for the 2D bridge. The 'Label' attribute links the 2d_po line to the 2d_po points by the same attribute ‘Bridge’.
<li>The 2d_po line is snapped to the 2d_lfcsh from left to right looking downstream and has the following attributes: <br>
:*Type = QS (structure flow)
:*Label = Bridge
<li> The 2d_po points are digitised upstream and downstream of the 2d_lfcsh and have the following attributes: <br>
:*Type = HU (water level upstream) and HD (water level downstream)
:*Label = Bridge

= Conclusion =
:*The 2d_bg layer was supplied for use as a 2D bridge.
