# EPANET: [JUNCTIONS]

[JUNCTIONS]

Purpose:

Defines junction nodes contained in the network.

Format:

One line for each junction containing:

- ID label
- Elevation, ft (m)
- Base demand flow (flow units) (optional)
- Demand pattern ID (optional)

Remarks:

1. A [JUNCTIONS] section with at least one junction is required.
2. If no demand pattern is supplied then the junction demand follows the Default Demand Pattern provided in the [OPTIONS] section, or Pattern 1 if no Default Pattern is specified. If the Default Pattern (or Pattern 1) does not exist, then the demand remains constant.
3. Demands can also be entered in the [DEMANDS] section and include multiple demand categories per junction.

Example:

[JUNCTIONS]
;ID Elev. Demand Pattern
;------------------------------
J1 100 50 Pat1
J2 120 10 ;Uses default demand pattern
J3 115 ;No demand at this junction
