Scenario input sets allow you to easily keep model structure, while switching between groups of input data and parameters. These may be used to represent changeable physical attributes, such as climate, land use decisions or even proposed infrastructure characteristics. You can switch between different scenario input sets to compare the effects on a model. For example, you can have one scenario input set consisting of rainfall, inflow and evapotranspiration data for natural conditions, another for wet conditions and a third set for dry conditions.

...

Child scenario input sets allow you to further refine model structure. A child scenario input set inherits all parameters and data sources specified in its parent. You can then set additional parameters, or alter existing ones. When you choose to run a model with the a child scenario input set, for any parameters that differ between the parent and child, the parameters from the child will take precedence over the parameters from the parent.

For parent and child scenario input sets:

  • You can create children of a child, thus creating nested scenario input sets. Every child scenario input set inherits all parameters

  • Data sources can only be assigned to the root-level parents (Dry Weather, Wet Weather and Default Input Set in Figure 4).
  • Deleting a parent will delete all of its children.
