To build an SRH-2D model in SMS, use the following steps:
1. SMS setup.
|
1. Start SMS, or clear existing projects in SMS.
|
- If SMS is already running, select File | Delete All.
- A new project can also be started by using CTRL + N.
|
|
2. Import data.
|
1. Gather and open image files.
|
Images are imported into the GIS module in SMS.
2. Import images from the web.
|
|
|
|
4. Define model limits (domain).
|
- Generate a Mesh Generator map coverage.
- Digitize arcs to define mesh limits.
- Define mesh density and type (in Mesh Generator coverage).
- Create arcs along key breaklines and notable features (banklines, structures, piers, road embankments, etc.).
- Set vertex spacing on arcs to define mesh element size.
- Specify mesh type for each polygon (pave / patch / none).
- Assign scatter data.
- Generate mesh.
|
5. Define materials.
|
- Create a SRH-2D Materials coverage.
- Digitize material areas (polygons).
- Define material types and Manning’s roughness values.
- Defining materials from land use GIS data.
|
6. Set-up boundary conditions.
|
- Create a Boundary Conditions coverage.
- Multiple boundary condition coverages can be created if needed, but only one boundary condition coverage can be added to simulation. Boundary conditions coverages can be merged together if needed.
- 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.
- Optional Wall boundary conditions.
- Structures (culverts, weirs, bridge pressure flow).
- See also: SRH Culvert Workflow, SRH Pressure Flow Bridge Workflow
|
7. Set monitoring points.
|
- Create a Monitoring Points coverage.
- Create feature points in the coverage.
|
8. Define obstructions.
|
- Create a SRH-2D Obstructions coverage.
- Add feature arcs and points to coverage.
- Assign obstruction parameters to feature arcs and points.
|
10. Review results.
|
- Open _XMDF file.
- Results layers.
- Observation lines.
- Summary table.
- Run the Plot Wizard.
- Data calculator.
|
11. Compare datasets.
|
- Create activity datasets
- Create scalar datasets
- Create vector datasets
