Example of the Advanced Simulation dialog showing the "Scenarios" run type

In additional to standard simulation runs, SRH-2D allows for running multiple simulations runs at once using a set of parameters to vary each model run. Running multiple simulations in this way can be used to either create alternate scenarios or it can be used to help calibrate the model.

Before using the advanced simulation options, it is recommended that a successful model run of the SRH-2D model be completed.

The Advanced Simulation dialog is accessed by right-clicking on the simulation item in the Project Explorer and selecting the Advanced Simulation option.

The Advanced Simulation dialog has the following options:

• Use parameters – Turning on this option activates the advanced simulation options. The advanced simulation runs will execute when using the Save and Run Simulation command.
• Run type – Can be set to "Scenarios" or "Calibration". The selected run type will determine the options in the rest of the dialog. See the following sections for details on each of the options.

Scenarios

• Show type – This drop-down menu allows sorting the different available parameters. The available parameters are based on the each individual SRH-2D project. All parameters are shown when "All" is select. The other options will only show the selected parameter type.
• Available parameters – This table allows setting which parameters will be available for the different model run scenarios. The parameters listed in the table are determined by the individual SRH-2D model. Typical parameters that may be available include inlet and outlet boundary conditions, material roughness, time step controls, and initial conditions controls.
