The Scenario Manager allows you to create, edit, and manage an unlimited number of scenarios. There is one built-in default scenario—the Base scenario. If you want, you only have to use this one scenario. However, you can save yourself time by creating additional scenarios that reference the alternatives needed to perform and recall the results of each of your calculations.

The Scenario Manager consists of a hierarchical tree view and a toolbar. The tree view displays all of the scenarios in the hydraulic model. If the Property Editor is open, clicking a scenario in the list causes the alternatives that make up the scenario to open. If the Property Editor is not open, you can display the alternatives and scenario information by selecting the desired scenario and right-clicking on Properties.
