2.3.4 Sprinkler Irrigation Systems
2.3.4.1 Concept and Features
In sprinkler irrigation, water is delivered through a pressurized pipe network to
sprinklers, nozzles, or jets which spray the water into the air, to fall to the soil
system, where water is distributed through a network of pipe lines to and in the field
and applied through selected sprinkler heads or water applicators.
The basic components of any sprinkler system are
•
a water source
•
a pump (to pressurize the water)
•
a pipe network (to distribute the water throughout the field)
•
sprinklers (to spray the water over the ground) and
•
valves (to control the flow of water)
In addition, flow meters and pressure gauges are sometimes added to monitor
system performance.
The sprinklers, when properly spaced, give a relatively uniform application
of water over the irrigated area. Sprinkler systems are usually (there are some
