Distribution Uniformity: Test for determining the evenness of water applied by sprinkler irrigation
Coefficient of Uniformity : Value representing the evenness of water application
Statistical Uniformity : Calculated uniformity of water delivery by microirrigation based on a nomograph
Uniformity : Evenness of similarity in amount of water delivered over or within an area
Irrigation Application Efficiency : Percentage of applied water in root zone and available for plant use
Irrigation Water Use Efficiency : Percentage of applied water used by the plant
Operating Pressure : Pressure at which irrigation system should operate to achieve a specific delivery based on specifications of the infrastructure
Application Rate : Amount of water applied in a specific time
Sprinkler Irrigation : Water drops that fall freely from above plants
