Drip Irrigation Field Uniformity Estimation

Abstract

ABSTRACT THE coefficient of variation was used to assess the magnitude of emitter flow variation in drip irrigation submain units. Based upon the assumption that emitter flow variation is normally distributed, a simplified statistical method for estimating the coefficient of variation was developed. The estimate of the coefficient of variation was used to demonstrate a method of determining field uniformity for drip irrigation submain units. A graphical technique for estimating the statistical uniformity and the relative confidence limits of the proposed method were presented.
