Child scenario input sets allow you to further refine model scenarios. A child scenario input set inherits all parameters and data sources specified in its parents. If changes are made to the parent . You scenario input set, existing and new children will inherit those changes. You can then set additional parameters, or alter existing ones, overwriting the inherited parameters. When you run a model with a child scenario input set, for any parameters that differ between the parent and child, the parameters from the child will take precedence.

- You can create 'grandchildren', thus creating nested scenario input sets. Every Every child scenario input set inherits all parameters above it in its branch, and ignores any parameters set in its children.
- Deleting a parent will delete all of its children.
- Within both the Configure dialog (Figure 1) and Results Manager (LINK to naming), child scenario input sets are referred to be their full path, eg. Dry Weather.Water Restriction Level 1.New Dam.

- Select You can use this dialog to copy the assigned data sources from another root-level scenario input set to this one. From the drop down menu, select the scenario input set from which to copy the data source usages, either one of the existing root-level scenario input sets or <Empty>, which will not copy usages from anywhere. or select <Empty> if you do not wish to assign data sources at this time.
To add a new child scenario input set:
- Right-click on the scenario input set that you wish to be the parent, and choose Add Child Scenario Input Set from the contextual menu (Figure 1).
