To build a SRH-2D model in SMS, use the following steps:
[show ] 1. SMS project setup.
Expand 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 .
[show ] 2. Import data.
Import any of the following data as needed:
Background images (World Image, static image, resolutions, etc.).
Elevation data (cover range of formats, Lidar , DEM, XYZ , Raster , etc.).
GIS data (Land Use, etc.).
CAD data (project features, alignment, etc.).
[show ] 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 .
[show ] 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.
[show ] 6. Set-up boundary conditions.
Create a SRH-2D Boundary Conditions coverage.
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).
[show ] 7. Set monitoring points.
Create a SRH-2D Monitoring Points coverage.
Create feature points in the coverage.
[show ] 8. Define obstructions.
Create a SRH-2D Obstructions coverage.
Add arcs to coverage.
Assign obstruction parameters to arcs.
[show ] 10. Review results.
