Describing Irrigation Efficiency and Uniformity

To help standardize system design and evaluation terminology, a limited number of the more essential terms defining efficiency of water application and distribution by irrigation systems are presented. These definitions have been formulated to minimize conflict with common usage or existing glossaries. Where methods of evaluating the terms are not obvious, suggestions have been presented and the utility of the terms in irrigation system design or evaluation has been discussed. Application of the terms to some of the newly developing methods of irrigation has also been considered.
