Irrigation Efficiency Calculator
Simple DU Calculator
Northern California Irrigation Efficiency Calculator
Estimate crop water use and irrigation runtime using typical Northern California reference evapotranspiration (ETo), crop coefficients (Kc), system application rate, and distribution uniformity (DU).
Enter inches applied per hour (decimal format).
DU must be entered as a decimal between 0 and 1 (example: 0.75 = 75% uniformity).
DU Comparison Calculator
Distribution Uniformity (DU) Improvement Calculator
Compare how improving irrigation system distribution uniformity (DU) changes runtime and water use.
Enter inches applied per hour (decimal format).
Enter DU as decimal between 0 and 1.
Enter DU as decimal between 0 and 1.
