Automatic irrigation is the use of a device to operate irrigation structures so the change of flow of water from one bay, or set of bays, to another can occur in the absence of the irrigator.
Automation can be used in a number of ways:
- to start and stop irrigation through supply channel outlets,
- to start and stop pumps,
- to cut off the flow of water from one irrigation area – either a bay or a section of channel and directing the water to another area.
These changes occur automatically without any direct manual effort, but the irrigator may need to spend time preparing the system at the start of the irrigation and maintaining the components so it works properly.
