What-If scenarios can be applied in DELFT-FEWS to explore the influence of uncertainties in input data, module structure and module parameters. When running a forecast, a what-if scenario may be selected from a list of available scenarios. A display plug-in is available to define what-if scenarios.

description
Optional description of the configuration. Used for reference purposes only.
variableSets
Definition of variables (time series) of what-if scenarios may be applied to.
...
- variableId : ID of the variable (group). Appears in list of variable to be selected in defining a what-if scenario in the display.
- variableType : Optional type definition of variable (default to "any")
- convertDatum : Optional Boolean flag to indicate if datum is to be converted for the what-if scenario defined. This may be required when defining a typical profile what-if scenario.
configFiles
Template for defining what-if scenario applied to module parameters and module datasets. These templates are used when creating the what-if scenario. Should be defined using optional/required elements if what-if scenarios for module parameters and module datasets are to be supported.

timeSeriesSet
Time series set the what-if scenario is to be defined for. The relative view period over which the what-if scenario applies changes to the data is defined in the TimeSeriesSet. startOverrulable or endOverrulable are ignored, thus only the hard-coded relative view period will be applied.
relativeT0DateFormat
The scenario editors by default show times where T0 is based on the current system time.To only show relative times to T0, the relativeT0DateFormat can be used by configuring the following:
