Selecting the Reservoir Guide Curve

The top of zone curve of any zone in your reservoir can be selected to represent the Guide Curve (i.e., target elevation) of your reservoir. The guide curve (or rule curve) represents the basic objective of the reservoir − get the pool elevation to, and hold it at, the guide curve. Without any other operational constraints, the decision logic will attempt to get to and keep the reservoir at the guide curve, within maximum outlet capacity and physical rate of change constraints. By default, the zone initially labeled Conservation is selected as the guide curve.

To select a different zone to represent the guide curve for your reservoir operation set:

• Right-click on the zone to be used as the guide curve in the Zone-Rules Tree and select Set Guide Curve ("Figure: Set Guide Curve") from the context menu.
• The name of the zone that is defined as the Guide Curve will be displayed with bold text in the Zone-Rules Tree.
