SMS:SRH-2D Culvert Workflow

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

1. SRH-2D project setup.

1. Create a new SRH-2D simulation. After creating the components of a simulation, create a new SRH-2D simulation. Right-click in the Project Explorer and select the New Simulations | SRH-2D command. 2. Add SRH-2D simulation components. To link components to the simulation, do one of the following. Right-click on the component and select the simulation name from the Apply To submenu. In the Project Explorer, click and drag items under the simulation object. 3. Set SRH-2D model parameters. Right-click on the simulation and select the Model Control command. Set the model parameters in the SRH-2D Model Control dialog. 4. Run the SRH-2D simulation. Right-click on the SRH-2D simulation and select Save Project, Simulation and Run to run the simulation. Use the Simulation Run Queue to track the model run.

2. Create culvert boundary conditions.
Create a boundary conditions coverage. Create boundary condition arcs for the culvert. Specify the HY-8 culvert definition file. Assign the boundary condition attributes and define the culvert in HY-8. Modify the materials coverage.

3. Specify the initial conditions of the stream.
Create new simulation. Add components to simulation. Set up the simulation Model Control parameters. Specify the restart conditions file under initial conditions.

4. Run the SRH-2D simulation.
Check the model. Simulation execution. Troubleshooting.

5. Review results.
Open _XMDF file. Results layers. Observation lines. Summary table. Run the Plot Wizard. Data calculator.
