EPANET - Reservoir

Reservoirs are nodes that represent an external infinite source or sink of water for the network. They are used to model things like lakes, rivers, underground aquifers, and connections to other systems. Reservoirs can also serve as points of water quality sources.

The main inlet properties of a reservoir are its hydraulic head and initial water quality. As a reservoir is a boundary point for a network, its depth and water quality cannot be affected by what happens within the network. Therefore, it has no computed output properties. However, its depth can vary over time by assigning an time pattern to it.

In addition to the shared properties of EPANET Nodes, reservoirs also have the following properties:

• Reservoir
  • HeadPattern - Head Pattern used to model time variation of total reservoir depth
• Epanet
  • Elevation - Elevation of the water intake
• Calculations - are filled in by the command EPANETCALC, when it succeeds in the simulation
  • Flow Balance - Flow Balance
  • Water Level - Calculated water level for the reservoir

Obviously, the entire reservoir is not modeled in the Constructor, since it depends on the topography anyway. In the case of the reservoir, model the water intake:

Note the point marked "Connector" is the elevation of the water intake shown in the properties frame above

For a device to be recognized as an EPANET reservoir, the Constructor must contain an activity Reservoir:
