<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>The 1d_nwk bridge layer represents a bridge in 1D at the upstream and downstream road crossing. Type attribute ‘BB’ is specified, only pier loss and submerged deck loss coefficients are required, all other losses are automatically calculated.

<li>The 1d_nwk weir layer represents a weir for flow over the bridge in 1D at the downstream road crossing. Type attribute 'W' is specified, the weir is based on the broad crested weir formula:

<li>The tool removes the source layer from the Layers panel and the '''2d_code_M11_null_creek_002_R''' appears.
<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>Zoom to the downstream road crossing and right click on the layer to toggle on Editing.
<li>Click on the 'Add Polygon Feature' tool and draw a polygon snapped to the existing polygons.
<li>Set the attribute as '0'.
<li>Click 'OK' and turn off editing to save the edits.

Increment the Z shape layer to change the elevation of the river banks at the downstream road: 
<ol>
<li>Navigate to the '''Module_11\model\gis''' folder and open the '''2d_zsh_M11_hx_001_L.shp''' in QGIS.
<li>Select the '''2d_zsh_M11_hx_001_L''' layer in the Layers panel.
<li>Click on the ‘Increment Selected Layer’ symbol from the TUFLOW Plugin toolbar.
<li>The tool automatically renames the '''2d_zsh_M11_hx_''001''_L''' to '''2d_zsh_M11_hx_''002''_L'''.
<li>Select to 'Remove Source Layer from Workspace' and click 'OK'. 
<li>The tool removes the source layer from the Layers panel and the '''2d_zsh_M11_hx_002_L''' appears.
<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>Zoom to the downstream road crossing and right click on the layer to toggle on Editing.
<li>Delete the two HX lines that intersect with the creek and digitise two new HX lines joining the existing lines following the bank.
<li>Set the 'Shape_Option' attribute as 'MAX'.
<li>Click 'OK' and turn off editing to save the edits.

Increment the boundary condition layer to change the HX boundary at the downstream road: 
<ol>
<li>Navigate to the '''Module_11\model\gis''' folder and open the '''2d_bc_M11_hx_001_L.shp''' in QGIS.
<li>Select the '''2d_bc_M11_hx_001_L''' layer in the Layers panel.
<li>Click on the ‘Increment Selected Layer’ symbol from the TUFLOW Plugin toolbar.
<li>The tool automatically renames the '''2d_bc_M11_hx_''001''_L''' to '''2d_bc_M11_hx_''002''_L'''.
<li>Select to 'Remove Source Layer from Workspace' and click 'OK'. 
<li>The tool removes the source layer from the Layers panel and the '''2d_bc_M11_hx_002_L''' appears.
<li>Use the 'Apply TUFLOW Styles to Open Layers'.
<li>Zoom to the downstream road crossing and right click on the layer to toggle on Editing.
<li>Water from 1D does not transition to 2D at this location anymore, delete the two HX lines intersecting the open channel. The water at the 1D channel node is transferred to the banks by the CN lines, all four CN lines remain:

<li>Create new HX lines connecting the current HX lines on the banks of the open channel:
<li>Click 'OK' and turn off editing to save the edits.

= Conclusion =
:*Two bridges were set up in 1D replacing two culverts within the open channel. The upstream bridge overtops into the 2D domain, the downstream bridge overtops into a 1D weir.
:*The active area, banks elevation and boundary condition layers were updated to model the downstream bridge overtopping in 1D.
