Controls are statements that determine how the network is operated over time. They specify the status or setting of selected links as a function of time, tank water levels, and pressures at select points within the network. There are two categories of controls that can be used:

•Simple Controls

•Rule-Based Controls

 

Simple controls change the status or setting of a link, based on:

•the water level in a tank,

•the pressure at a node,

•the time into the simulation,

•the time of day.

 

Rule-Based Controls allow link status and setting to be based on a combination of conditions that might exist in the network, after an initial hydraulic state of the system is computed.
