Using a Time Window Modifier in an HEC-WAT Simulation

To add an existing Time Window Modifier alternative to a simulation the user must use a Program Order containing the Time Window Modifier Plugin. 

The Time Window Modifier can be used by Plugins in the Program Order below the Time Window Modifier. Place the Time Window Modifier high enough in the Program Order so that it can be leveraged by any model alternatives to apply the time window modification. Note that multiple time window modifier alternatives can be defined within one simulation, each modifying the Simulation Time Window, or creating successive modifications of the Time Window.

If multiple model alternatives need the same modified time window they can reference the same output from the Time Window Modifier alternative.
