Distribution Uniformity (DU):
.
A common metric for evaluating sprinkler system uniformity is Distribution Uniformity, calculated by dividing the average water applied to the lowest quarter of the area by the overall average depth, according to Michigan State University.
Coefficient of Uniformity (CU):
.
CU is another metric, often used for drip irrigation, that indicates the uniformity of water application.
