Evaluation of microirrigation uniformity on laterals considering field slopes.

Water application uniformity is an important performance criterion that must be considered during the design and evaluation of the microirrigation systems. This study was conducted to evaluate the water application uniformity considering field slopes. The uniformity parameters including coefficient of variation (CV), Christiansen’s uniformity coefficient (UCC), distribution uniformity (DU), emitter discharge variation qv ( q max ) expressed by the difference between the maximum emitter flow rate qmax and the minimum emitter flow rate qmin to qmax , emitter discharge variation qv ( qd ) expressed by the difference between qmax and qmin to design emitter flow rate qd , emitter discharge variation qv ( qd ) expressed by the difference between qmax and qmin to average emitter flow rate q ( avg ) , emission uniformity ( EU ( q avg ) ) expressed by qmin to qavg , and EU ( qd ) expressed by qmin to qd . Furthermore, the relationships of CV versus UCC, CV versus DU, CV versus qv ( qd ) , CV versus qv ( q max ) , ...
