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

3. Review and edit elevation data.
  1. Review and set object Projections.
  2. Remove erroneous points.
  3. Add breaklines.
  4. Merge datasets.
  5. Stamp new features (channel, roadway embankment, or other).
See also: Feature Stamping Workflow
4. Define model limits (domain).
  1. Generate a Mesh Generator map coverage.
  2. Digitize arcs to define mesh limits.
  3. Define mesh density and type (in Mesh Generator coverage).
  4. Create arcs along key breaklines and notable features (banklines, structures, piers, road embankments, etc.).
  5. Set vertex spacing on arcs to define mesh element size.
  6. Specify mesh type for each polygon (pave / patch / none).
  7. Assign scatter data.
  8. Generate mesh.
5. Define materials.
  1. Create a SRH-2D Materials coverage.
  2. Digitize material areas (polygons).
  3. Define material types and Manning’s roughness values.
  4. Defining materials from land use GIS data.
6. Set-up initial boundary conditions.
  1. Create a Boundary Conditions coverage.
  2. Assign boundary conditions to arcs.
    • Inlet Q (options).
    • Exit-H (options, including new normal/critical depth tool).
    • Internal inflows and outflows (highlight approach – hole in mesh).
    • Monitoring Lines.
7. Create culvert boundary conditions.
  1. Create boundary condition arcs for the culvert.
  2. Specify the HY-8 culvert definition file.
  3. Assign the boundary condition attributes and define the culvert in HY-8.
  4. Modify the materials coverage.
8. Specify the initial conditions of the stream.
9. 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.
10. 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.
