If you have made changes to the forecast, you will be given options on how to manage those change, further details are provided in Managing Forecast Data of this chapter. HEC-RTS will unload all information associated with the active forecast and the Modeling module (Modeling Module - Forecast Information Displayed) will be blank.

Edit the Time Window

If you want to change any of the dates or times associated with the active forecast, from the HEC-RTS main window, click the Modeling tab, from the Forecast menu, click Edit Time Window. The Forecast Time Window dialog (Figure 3) will open. In the Forecast Time Window dialog, enter the new information in the corresponding date and time fields.
