2. Proper design of an irrigation
system requires that the
pumping system precisely
match to the irrigation
distribution system so that
the pressure and flow rate
required can be efficiently
provided by the pumping
system.
3. Irrigation water
management involves
determining when to
irrigate, the amount of water
to apply at each irrigation
event and during each stage
of plant, and operating and
maintaining the irrigation
system.
5. The primary function of
farm irrigation systems is
to supply crops with
irrigation water in the
quantities and at the time
it is needed. Specific
function includes:
6. 1. Diverting water
from the water
source.
2. Conveying it to
individual fields
within the farm
9. •A project plan enables the
designer to lay out the
irrigation system in the
most cost effective way.
•The plan provides step by
step information on system
installation.
10. •Specification, design standards and
work schedules as set out on a
plan form the basis of any
contractual agreements between
the installation contractor and the
farmer.
•The plan provides a record for
future reference. It can be used for
overall farm planning and identifies
limits of expansion potential.
12. •Topographic Data
• Water Source Capacity
• Depending on the water source, a
well log or water license must
accompany the irrigation plan.
•Soil and Crop Characteristics
•Design Parameters
•Design Data
