Template:SRH Pressure with 3D Bridges Workflow

1. Create 3D bridge arcs.
See the 3D Bridge workflow for instructions on how to do this.

2. Create a link structure.
Using the Select Feature Arc tool, select both bridge pressure flow arcs. Right-click and select the Assign Linear BC... command. In the SRH-2D Linear BC dialog, assign the bridge pressure flow boundary conditions specifying the upstream and downstream arcs and the ceiling elevation and Manning roughness coefficient.
