They are defined in Part 2 as part of the instructions for playing the game. The regulation of outflow from a reservoir by opening or closing valves, gates, or other controls. Rule curves specify a target reservoir stage throughout the year. The stage is the elevation of water in the reservoir. Since the amount of water in the reservoir increases with increasing stage, the stage is an indicator of storage volume.
Simulators recreate actual events or conditions, often for training purposes.
For example, pilots train with a flight simulator to recreate the experience of flying an airplane. The Reservoir Game is a simulator that recreates the operation of a reservoir. The unregulated outflow of water from a reservoir that occurs when its maximum storage capacity is exceeded. In the Reservoir Game, static reservoir operation means making decisions to release water from the reservoir without using any information about the watershed state. Static operations in the Reservoir Game follow a rule curve.
