Computerized Hole Selection (CHS) is a computer software application which designs
and evaluates furrow irrigation systems. CHS uses pipe friction loss, pipe elevations and flow rate, and pressure
to calculate punched hole sizes in layflat tubing (flexible poly-pipe) for uniform
application of water, even in systems with varying row lengths. Down-row uniformity
means rows are watered evenly, reducing tail water, improving irrigation efficiency
and conserving water and energy. Use of CHS has the potential to reduce water usage
and irrigation cost by 25% or more in most cases.
The PHAUCET (Pipe Hole and Universal Crown Evaluation Tool) is a free GNU General Public License (GPL) computer software application. It was designed by engineers with the National Resources
Conservation Service (NRCS) in Missouri to calculate existing irrigation system performance
and define alternatives for improving irrigation efficiency.
PHAUCET assists farmers determine the sizes of the holes in the layflat flexible poly-pipe
that best distribute the available water. The program also helps farmers improve timeliness
of watering fields having different row lengths.
