General Description of Scenario Explorer and how to Compare Scenarios in InfoSWMM and InfoSWMM SA

Launch Scenario Explorer by selecting Scenario Explorer from the InfoSWMM and InfoSWMM SA Scenario Menu or by clicking the Scenario Explorer button () on the InfoSWMM H2OMap SWMM InfoSWMM SA Control Center Toolbar Standard Toolbar . You will see the following dialog box.

Contents of the scenario Explorer dialog box are briefly described below:

Button	Name	Description
	Activate	Activates the selected/highlighted scenario.
	New Scenario	Creates a new "child scenario" under the currently selected/highlighted scenario
	Reset Changes	Resets the selected/highlighted scenario to its original status
	Delete Scenario	Deletes the currently selected/highlighted scenario
	Edit Scenario Description	Allows you to change the description of the currently selected/highlighted scenario
	ID Counter	Use this to set the automatic Scenario ID assignment option by selecting the Prefix, Id counter, and the increment steps as you wish.
	Save as Default	Saves the selected scenario as a default and automatically inherits its contents to newly created scenarios
	Copy	Copies the input data information of the selected/highlighted scenario to the clipboard. After using the tool, the Paste and Replace and Paste as Child tools will be activated and can be used to transfer the information to another scenario.
	Paste and Replace	Pastes the input data information copied to the clipboard and replaces the existing data of the currently selected/highlighted scenario
	Paste as Child	Pastes the copied scenario from the clipboard and saves it as a new "child scenario" under the currently selected/highlighted scenario
	Edit Active Scenario	While working in the Scenario Explorer, the currently active scenario cannot be changed or edited. To edit the datasets associated with the active scenario, click this Edit Active Scenario button. To change items on the General or Facility tabs, you must make another scenario active (at least temporarily).
	Batch Run	With the Batch Simulation Manager, the user can select the desired scenarios and run each model in a "batch" (i.e., at a time).
	Compare Scenarios	Opens the Scenario Data Comparison Report. The last comparison will be displayed. The report has a button to create a new comparison if desired.
	Exit	Exit Scenario Explorer
	Help	Opens this help file
	Scenario Display Window	IDs and descriptions of the available scenarios is displayed here. In addition, the relationship between a parent scenario and its child, defined as inheritance, is displayed in this box. InfoSWMM shows this relationship in the form of a directory tree. All scenarios are children of the *BASE* scenario until some element of the child is made unique from the parent (such uniqueness comes in the form of data sets, facility sets, or option sets). In the example below, RUN_14 is a child of RUN_12, RUN_12 is a child of RUN_10, and RUN_10 is a child of BASE. When a change is made to a parent, unless some facet of a child is unique, it will inherit the change through inheritance.
	General Tab	The Scenario Explorer - General tab enables editing of InfoSWMM H2OMap SWMM InfoSWMM SA 's simulation and report option parameters, and the climatology settings for the selected/highlighted scenario.
	Facility Tab	The Scenario Explorer - Facility tab enables adding/removing facilities to/from a scenario.
	Data Set Tab	The Scenario Explorer - Data Set tab enables modifying input data for InfoSWMM H2OMap SWMM InfoSWMM SA 's visual and non-visual data objects.

Compare Scenario Data (Input Data)

InfoSWMM H2OMap SWMM InfoSWMM SA’s Compare Data Scenario command allows you to easily monitor the differences in input data between any two scenarios in a model.

Initiating Compare Scenario Data

To initiate the Compare Data Scenario dialog box indicated below, do the following:

Select Compare Data Scenario from the InfoSWMM H2OMap SWMM InfoSWMM SA Scenario Menu. This will display the following dialog box.

Scenario Data Comparison Report

Scenario Comparison results are presented in a format that allows the user to readily compare each scenario’s data. When the comparison analysis is completed, the model will be presented with a display similar to the report indicated below. This provides users with summary of all the data differences associated with the scenarios. The following is what each of the summaries describe:

Compare Scenario Data Methodology

To Compare two Scenarios do the following:

• Select the first scenario you wish to compare from the Scenario #1 drop down list.
• From the Scenario #2 drop down list, select the scenario you wish to compare to the first scenario.
• If you wish to save the comparison result, you can save selection sets to refer to at a later time (i.e. from the Domain Manager). For information on creating a selection set, refer to selection sets. you must have different selection sets selected for each comparison result that is to be reported. If you wish to overwrite an existing Selection Set, ensure that the Overwrite option is checked.
• You can select an existing Selection Set to use, or you can create a new selection set. If you wish to save a Selection Set based on the elements that are in Scenario #1, but not in Scenario #2, check the Save elements that exist in Scenario #1 only option.
• Alternately check the Save elements that exist in Scenario #2 only option to save a Selection Set based on the elements that are in Scenario #2, but not in Scenario #1.
• If you wish to save a Selection Set based on elements that have different values between the two scenarios, check the Save elements that have different values option.
• To alter the colors selected for each of the Compare Scenario outputs, click on the color swatch you wish to change, and a color pick dialog will appear for you to select a new color. Each color that is selected in this dialog will be reflected in the Data Scenario Comparison Report legend.
• To conduct a comparison of scenarios, press the button. Results will be displayed in the scenario comparison report.
