Selecting Forecast (

Figure 3) allows you to forecast flows in two ways. Unlike Operations, it does not require a run of the warm period to initialise its calculations. The Operations Forecast Model is used in an ordering system, and determines how much flow might occur. These forecasts are needed in addition to what is in storages to determine how much water might be available to distribute in the current and coming days. As its name suggests, Recession Forecast Model creates a recession forecast model for the network defined in the Schematic Editor.

Forecast Multiplier

Inflow Nodes have a "Forecast Multiplier" option that is enabled by right clicking and selecting "Enable". The forecast Multiplier can be input as a fixed value, data source or function and is configurable by Scenario Input Sets.  The multiplier only affects the forecast inflow and has no affect on the current inflow.

more information on configuring them, refer to Constituents - Inflow.

Ownership

Ensure that ownership is enabled in the scenario (using Edit » Ownership) prior to configuring it at this node. Refer to Ownership for details.
