What Is Water Distribution Uniformity?

Water distribution uniformity describes how evenly irrigation water is applied across an area.

Two rows of four identical collectors show relatively similar water depths in the first row and different depths in the second, using the same test period. — Illustrative collector depths only. No uniformity percentage, pass threshold or product test result is asserted.

How It Can Be Observed

Equal-size collectors placed at different locations can show differences in applied water depth over the same test period. Formal uniformity metrics require a defined sampling method and calculation.

IrriSense 2 Product Context

Aiper describes EvenRain as a water-distribution feature of IrriSense 2. The illustration explains evenness in general and is not a measurement or independent certification of that feature.

Common Misunderstanding

Total water use, spray reach and distribution uniformity are different. An area can receive enough water on average while some locations remain relatively dry.
