CENTER PIVOT IRRIGATION SYSTEM MODIFICATION TO PROVIDE VARIABLE WATER APPLICATION DEPTHSPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Applied Engineering in Agriculture. 13(2): 235-239.

A multiple-segment water application system was developed and attached to a commercial center pivot
irrigation system to provide variable application depths within each segment at a given speed. Each segment was 9.15 m
(30 ft) long and consisted of three parallel manifolds sized to provide 1x, 2x, and 4x, where x is a minimum application
depth. The three manifolds could be operated individually or in various combinations to provide eight application rates
(0-7x) at any given tower velocity. Water application depth varied from 0 to 12.4 mm (0 to 0.5 in.) when the center pivot
was moving at 50% of full speed.
