Design of Irrigation Systems
Credits: 8 PDH
PDH Course Description:
This course provides a comprehensive overview of various types of irrigation systems. Systems described in this course include: surface, sprinkler, micro, and subirrigation types. The surface irrigation method is the application of irrigation water to
the soil surface by gravity.
With the sprinkle irrigation method, water is applied at the point of use by a system of nozzles (impact sprinkler heads, spray nozzles, etc.) with water delivered by surface or buried pipelines. Sprinkler irrigation systems are classed by operation of
the laterals. The three main types of sprinkle systems (laterals) are fixed, periodic move, and continuous/self move.
Micro irrigation is the broad classification of frequent, low volume, low pressure application of water on or beneath the soil surface by drippers, drip emitters, spaghetti tube, subsurface or surface drip tube, basin bubblers, and spray or mini sprinkler
systems. It is also referred to as drip or trickle irrigation.
Subirrigation is a water table management system that controls the elevation of a water table to provide water necessary for desired crop growth. A water table management system can lower an existing water table, maintain an existing water table, or raise
a water table to a desirable elevation. A water table is generally held at a constant elevation during a crop growing season, but can be fluctuated.
