ABSTRACT THE coefficient of variation was used to assess the magnitude of emitter flow variation along single chamber drip irrigation lateral lines. The relationship between hydraulic variation and manufacturing varia-tion was found to be orthogonal. This independent rela-tionship allows the statistical combination of their respective coefficients of variation. As a result the statistical uniformity coefficient was recommended for use in determining the drip irrigation lateral line design uniformity including manufacturing variation.
