To build an SRH-2D model in SMS, 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. Create SRH simulation components.
  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.

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.
