SMS:SRH-2D Pressure Flow Bridge Workflow

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

[show]1. SRH-2D project setup.

Expand1. 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. Expand2. 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. Expand3. 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. Expand4. 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.

[show]2. Create pressure flow boundary conditions.
The pressure flow boundary conditions must be defined before running the simulation. To do this: Create a boundary conditions coverage. Create boundary condition arcs for the pressure flow. Assign the boundary condition attributes to the pressure flow arcs. Modify the materials coverage.

[show]3. Specify the simulation parameters.
The initial conditions of the stream must be defined in the simulation. To do this: Create new simulation. Add components to simulation. Set up the simulation Model Control parameters. Specify the restart conditions file under initial conditions.

[show]4. Run the SRH-2D simulation.
Save the project. Check the model. Simulation execution. Troubleshooting.

[show]5. Review results.
Results for the pressure flow can be visualized by doing the following: Create observation arcs. Run the Plot Wizard.
