Computerized Hole Selection

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.

PHAUCET (Pipe Hole and Universal Crown Evaluation Tool)

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.
