To build an SRH-2D model using a pressure flow bridge, use the following steps:

2. Create pressure flow boundary conditions.
  1. Create boundary condition arcs.
  2. Specify the HY-* culvert definition file.
  3. Assign the boundary condition attributes and define the culvert in HY-8.
  4. Modify the materials coverage.
3. Specify the initial conditions of the stream.
4. SRH-2D simulation setup.
  1. Create new simulation.
  2. Add components to simulation.
  3. Set up Model Control parameters.
  4. Check the model.
  5. Simulation execution.
  6. Troubleshooting.
5. Review results.
  1. Open _XMDF file.
  2. Results layers.
  3. Observation lines.
  4. Summary table.
  5. Run the Plot Wizard.
  6. Data calculator.
11. Compare datasets.
  1. Create activity datasets
  2. Create scalar datasets
  3. Create vector datasets
12. Data visualization.
  1. View results in graphics window.
  2. Create data plots.
  3. Create a film loop visualization.
